WARNING
When working on the batteries wear proper protection and observe safety precautions Chapter

Battery handling instructions

Warning instructions and safety precautions for
lead acid batteries
1-

Observe the instructions on the battery, in the

Workshop Manual Electrical System and in
the Owner's Manual.

2 - Risk of acid burns:

-

Battery acid is highly caustic. For this reason

always wear protective gloves and eye
protection.

- Do not tilt battery as otherwise acid may flow

out of the vent openings.
3 - No fire, sparks, naked lights or smoking:
- Avoid creating sparks when handling cables
and electrical equipment.
- Avoid short circuits.
4 - Wear eye protection.
5 - Keep acid and batteries away from children.
6 - Disposal:
-

Old batteries must be disposed of in

compliance with the country specific
regulations.

7 - Never dispose of old batteries as domestic

waste!
8 - Risk of explosion:
- A highly explosive gas mixture is produced
when charging batteries.

Inspecting electrolyte level

Only top up with distilled water if the electrolyte level has dropped below the MIN marking.
Note
If the battery electrolyte level exceeds the MAX marking the electrolyte will leak from the battery
t
during operation (it is necessary to skim off electrolyte). An electrolyte level that is too low (below the
8

MIN marking shortens the battery life considerably. Top up with distilled water).
t

The battery plugs must always be inserted when charging the battery, measuring the voltage and
conducting a test under load.

t Always insert the plugs with O-rings after completing the test of the electrolyte density.

Measuring voltage under load

Note
Before disconnecting the battery determine the code of radio sets fitted with anti-theft coding.
First of all disconnect the battery earth strap.

Measure the voltage under load with a battery

tester, e.g. -V.A.G 1498-.
The load current and the minimum voltage differ
according to the capacity of the battery, refer to
the sticker on the tester or the table below.

Battery capacity Cold test current Load current Minimum voltage (limit value)
[Ah]
[A]
[A]
[V]
36

61 ... 80
300 ... 380
300
9,0
81 ... 110
380 ... 500
300
9,5
If the voltage measured is below the minimum voltage, replace the battery.
Explanations regarding battery load test:
The battery voltage drops during this test as a result of the high load on the battery (a high current flows).
If the battery is O.K., the voltage value drops only as far as the minimum voltage.
If the battery is faulty or only has a weak charge, the battery voltage will drop very rapidly below the
specified minimum voltage.
After completion of the test, the low voltage value is retained for a lengthy period, the voltage rises only
slowly again.
If the voltage measured under a load lasting for 5 to 10 sec. is below the minimum voltage, then the battery
is discharged or defective. The electrolyte density must be tested.

Basics
Battery types to be installed:
9

t Batteries with a magic eye and battery plugs covered in adhesive tape Chapter.
t Batteries with a magic eye but without battery plugs covered in adhesive tape (maintenance-free) Chapter.

Work sequence when disconnecting and connecting the battery

Disconnect battery
Note
Before disconnecting the battery determine the code of radio set fitted with anti-theft coding Operating
instructions of the radio.
Switch off all electrical components and take out the ignition key.
Slacken the nut (6 Nm) of the fixing screw for the pole terminal and only disconnect the battery earth strap.
Note
If both pole terminals are disconnected, only then disconnect pole terminal (-) from battery earth.
Connect up the battery
WARNING
Please observe the following additional instructions after working on the airbag system or on the belt tighteners
or the safety belts:
t Switch on the ignition before connecting the battery.
t Nobody should be in the vehicle when the battery is being connected.
Note
t Neither grease nor oil the battery terminals.
t

The battery terminals must only be fitted by hand without using any force in order to avoid damaging the
battery housing.

t Install the pole terminals in such a way that the battery pole with the terminal is on the same level or protrudes.
t If both pole terminals are disconnected, only then disconnect the positive terminal of the battery (+).

When connecting, fit pole terminal of earth lead

onto negative terminal of battery and tighten the
nut of the fixing screw -arrow- (6 Nm).

When the battery is reconnected perform the

following operations depending on the vehicle
equipment:
t Set clock
t

Check the window lifter/comfort electrics

Octavia.

Code radio sets with Safe coding Operating

instructions of the radio.

Other adjustments may have to be made according

to the engine which is installed (e.g generating a
readiness code). To do so use Vehicle diagnosis,
testing and information system VAS 5051

Check the battery

WARNING
When working on the battery - risk of accident. Observe the warning instructions and safety precautions
Chapter.
Check battery in the following sequence:
1 - Visual inspection Anchor.
2 - Check battery with a magic eye Chapter, Chapter.
3 - Testing the no-load voltage Chapter.
4 - Check measuring voltage under load Chapter.
Visual inspection
A visual inspection of the outer state of the battery, the cleanliness and of the fixed connections of the pole
terminals must be carried out before comprehensive measurements.
WARNING
When working on the battery - risk of accident. Observe the warning instructions and safety precautions
t
Chapter.
t Incorrect attachment of the battery can lead to damage. Carry out attachment inspection Chapter.
During the visual inspection determine:
If the battery housing is not damaged. In the event of damage to the battery housing e.g. the excess acid can lead
t to severe vehicle damage. In the event of excess acid the contamined vehicle parts must be immediately treated
with neutralizing agent or with a soapy solution. Paint damage must be repaired by a specialist.
t

If the battery terminals (connections of the battery cable) are not damaged and if the fixed connection of the
terminals is not destroyed in the event of damage to the battery terminals.

When connecting the battery pole terminals, pay attention to the specified procedure in this repair manual when
disconnecting and reconnecting the batteries, Chapter. If the battery terminals are not correctly connected and
t
tightened, the cable can ignite. This can result in extensive function problems of the electrical system. A safe
vehicle operation is no longer guaranteed.

Measure no-load voltage

Special tools and workshop equipment required
t Handheld multimeter, e.g. -V.A.G 1526A -.
Note
t The battery must not be drained by any electrical equipment for at least 2 hours before the measurement is taken.
t If the battery was charged, perform measurement only 2 hours after the performed charging.
Follow the procedure described below for measuring the battery voltage in the no-load state:
Use the handheld multimeter to measure the battery voltage.
The battery no-load voltage must not fall below 12.5 V.
If the handheld multimeter indicates 12.5 V or more, the battery voltage is O.K.
If the handheld multimeter indicates less than 12.5 V:
Charging battery Chapter
After charging wait at least 2 hours during which the battery with electrical components must not be subjected to
any load or charge:
Use the handheld multimeter to measure the battery voltage.
The battery no-load voltage must not fall below 12.5 V.
11

 If the no-load voltage is N.O.K., replace battery.

Charging batteries
WARNING
The battery plugs must always be securely tightened when charging the battery, measuring the voltage and
conducting a test under load to ensure they are really sealed.
Do not smoke or use a naked light in rooms in which batteries are being charged. The reason for this is that the
gases, which are generated in the batteries, can produce a dangerous explosive gas mixture when charging.
Frozen batteries must be replaced.
Special tools and workshop equipment required
t Battery charger, e.g. -VAS 5900-, -VAS 5903- or -VAS 5095A-.
Note
t Batteries must only be charged with chargers recommended by the manufacturer.
t

Carefully read through the operating instructions and observe during the charging before using the battery
charger.

t The battery must be at a temperature of at least 15C.

t

If a severely discharged battery is quick-charged, it will not accept any charge current or will be indicated as
properly charged too soon as a result of so-called surface charging. Such batteries then appear to be O.K.

Charging a battery
Connect the positive cable of the battery charger to the positive terminal of the battery.
Connect the negative cable of the battery charger to the negative terminal of the battery.
Switch on battery charger Operating instructions for battery charger
Severely discharged batteries
Explanations regarding severely discharged batteries:
Batteries which have not been operational for a long time, such as in stock vehicles, discharge themselves.
A battery is severely discharged if the no-load voltage has dropped below 11.6 V. Measure no-load voltage
Chapter
If a battery is severely discharged, the battery electrolyte (sulphuric acid/water mixture) consists practically only of
water as the sulphuric acid portion is greatly reduced.
Note
t The battery acid in severely discharged batteries can already freeze at low frost-point temperature.
t Frozen batteries must not be reused.
Severely discharged batteries sulfate, i.e. the entire surfaces of the plates harden. The battery acid is not clear but
has a white opacity.
If a severely discharged battery is re-charged immediately after losing its charge, the sulphate deposit forms again.
If such batteries are not re-charged in due time, the plates continue to harden and this considerably restricts their
ability to accept a charge. This results in a loss of battery capacity.

Removing and installing the battery

WARNING
Observe the battery handling instructions as well as the warning instructions and safety precautions for lead acid

Battery with a magic eye and battery plugs covered in adhesive

tape

Magic eye -1- is used for quickly determining the

battery state. The battery plugs -2- are covered in
plastic foil.
Note
The magic eye can be located at different points
on the battery lid.

Checking the battery using the magic eye

The magic eye gives information about the charge state and the electrolyte level of the battery via a colour indicator.
Note
The magic eye is located in one battery cell. Therefore, the reading is only relevant for this cell. An exact
t
assessment of the state of the battery is only possible by means of a battery load test Chapter.
When recharging the battery (via a charger or during operation), gas bubbles can form under the magic eye, which
t can distort the indicator regarding the battery state. For this reason before an inspection of the battery, tap lightly
and carefully on the magic eye. The gas bubbles rise in this way and the colour indicator becomes more accurate.
The battery indicator can show three different colours:
t Green - Battery is adequately charged up.
t Black - Battery is discharged or charged inadequately. The battery must be charged Chapter.
t Colourless or yellow - Electrolyte level too low. The battery must be replaced Chapter.
Note
We recommend to replace batteries which are older than 5 years of age.

Dash panel insert (? MY 00)
Self-diagnosis
General Instructions:
This description is also valid for 1.4 Itr/44 kW engines and 1.6 ltr./55 kW engines MY 01?.
Technology of the dash panel insert
The dash panel insert of the KODA Octavia is available in two versions. The basic version and the midline version
with multi-function display.
The multi-function display is integrated in the rev counter.
The following functions are indicated in the multi-function display:
t Digital clock
t Driving time and distance
t Average speed
t Average consumption
t Momentary consumption
t Outside temperature
The basic version is fitted only with a digital clock in the rev counter.
An LCD (liquid crystal display) is provided in the speedometer for the odometer, trip counter and service interval
display (SID).
The warning lights are integrated in the centre panel.
The dash panel insert is controlled by a microprocessor and features a comprehensive self-diagnosis. If faults occur
in the system components, fault codes are stored in the fault memory of the dash panel insert. These faults can be
detected using the diagnostic units -V.A.G 1552-, -V.A.G 1551- or -V.A.S 5051-.
Note
The following description only relates to the vehicle system tester -V.A.G 1552- using the program card 5.0. The use
of the fault read-out scan tool - V.A.G 1551- with the program card 8.0 is similar except for specific deviations (e.g.
different readouts in display, possibility of using a printer etc.).
In addition, the following adaptation functions can be performed:
t correction of fuel tank sender characteristic curve
t correction of fuel consumption gauge
t adjustment of service interval display
t adjustment of odometer when the dash panel insert is replaced
Information on replacing the dash panel insert
t The dash panel insert must not be disassembled.
t All the warning lights, which are formed of light bulbs, can be replaced separately Chapter.
t

If a replacement dash panel insert is fitted, the odometer reading and the service interval display can be adapted
using the vehicle system tester -V.A.G 1552 - or the fault read-out scan tool -V.A.G 1551 - Chapter.

If the control unit in the dash panel insert detects a fault in the programmed memory, the read-out dEF appears in
the trip counter.
If the read-out dEF appears, replace the dash panel insert Chapter.

Before replacing components found to be faulty, test all corresponding lines and plug connections to these
components according to the current flow diagram.

After repair always interrogate the fault memory using the vehicle system tester -V.A.G 1552- and erase the
memory.

All static and sporadic faults are stored in the fault memory: a fault is detected as static if it exists for at least 2
seconds (outside temperature fault after 60 seconds of running the engine, coolant temperature after 30

minutes of running the engine). If the fault is then no longer present, it is stored as a sporadic (temporary) fault.
/SP appears on the right of the display.
t

After switching on the ignition, all the faults which exist are set to sporadic and are not stored as static faults
unless they continue to exist after completing the check.

If a sporadic fault no longer occurs during 50 driving cycles (ignition on for at least 5 minutes, speed > 30 km/h),
it is erased.

Dash panel insert (MY 01 ?)

Self-diagnosis
General Instructions:
This description is not valid for 1.4 Itr/44 kW engines and 1.6 ltr./55 kW engines. The procedure is valid for these
engines Chapter.
Version Classic for data BUS engines
Rev counter, speedometer, coolant thermometer, fuel gauge sender, digital clock, LCD display for the odometer,
warning lights, 2nd and 3rd generation immobiliser with variable code.
Version Ambiente, Elegance for data BUS engines
Compared to the version Classic, the onboard computer MFD (instead of digital clock display) is installed.
Version with small dot display for data BUS engines (equipment: automatic gearbox or L&K)
Compared to the version Ambiente, the following functions still exist: small dot display, for the function display of
the onboard computer and the gears for the automatic gearbox.
Version with large dot display for data BUS engines (equipment: navigation)
Compared to the version Ambiente, the following functions still exist: large dot display, for the display of the
navigation pictograms, radio data, onboard computer and the gears for the automatic gearbox.
The following functions are indicated in the multi-function display (onboard computer MFD):
t Digital clock
t Driving time, driving distance and average speed
t Average consumption
t Momentary consumption
t Outside temperature
t Driving
The basic version (LX) is fitted only with a digital clock in the rev counter.
A display is provided in the speedometer for the odometer, trip counter and service interval display (SID).
The warning lights are designed as LEDs and cannot be replaced.
The dash panel insert is controlled by a microprocessor and features a comprehensive self-diagnosis. If faults occur
in the system components, fault codes are stored in the fault memory of the dash panel insert. These faults can be
detected using the diagnostic unit -V.A.G 1552-, -V.A.G 1551 - or -V.A.S 5051-.
Note
The following description only relates to the vehicle system tester -V.A.G 1552- using the program card 5.0. The use
of the fault read-out scan tool - V.A.G 1551- with the program card 8.0 or -V.A.S 5051- is similar except for specific
deviations (e.g. different readouts in display, possibility of using a printer etc.).
Use the self-diagnosis system to perform:
t adjustment of service interval display
t adjustment of odometer when the dash panel insert is replaced
Note
t The dash panel insert must not be disassembled.
t

If a replacement dash panel insert is fitted, the odometer reading and the service interval display must be adapted
using the vehicle system tester -V.A.G 1552-, or the fault read-out scan tool -V.A.S 5051- Chapter.

t After replacing the dash panel insert, the respective adaptation values must be entered Chapter.
If the control unit in the dash panel insert detects a fault in the programmed memory, the read-out dEF appears in
48

the odometer. Then the dash panel insert must be replaced Chapter.

Input values when changing the dash panel insert

Absolutely pay attention to the following points when changing the dash panel insert:
Note
The parameter which is set can be deducted with the diagnosis from the dash panel insert which was changed
t (function 10 adaptation, channels 40-41, diesel 47-48, petrol 46). Furthermore the coding and the km reading are
registered.
t The residual values since the last inspection service must be entered!
In countries with a speedometer reading in mileage, the adaptation of the service interval display (SID) must be
t carried out in kilometres! For this purpose, convert the adaptation values from miles into kilometres or enter the
previously noted adaptation values (1 mile = 1.609 km).
t

The immobiliser control unit is integrated in the dash panel insert, this means that when changing the dash panel
insert, the immobiliser control unit is also replaced and must be adapted!

t After changing the dash panel insert, the following steps must be carried out:
Adaptation of the immobiliser control unit Chapter.
Adapt ignition key Chapter.
Adapt odometer reading (mileage reading) Chapter.
Perform coding of the dash panel insert page Chapter.
Adapt service interval display Chapter.
Set the desired language version (only on dash panel inserts with dot display) .

according to the 5-digit fault code.
t

After repair always interrogate the fault memory using the vehicle system tester -V.A.G 1552- and erase the
memory.

All static and sporadic faults are stored in the fault memory: a fault is detected as static if it exists for at least 2
t seconds. If the fault is then no longer present, it is stored as a sporadic (temporary) fault. /SP appears on the

Telephone systems
WARNING
Disconnect earth strap from the battery before commencing work on the electrical system.
Note
t Before disconnecting the battery determine the code of radio sets fitted with anti-theft coding.
t After connecting the battery, perform the following:
on vehicles with radio encoding, carry out the coding,
set clock,
initialise power windows on vehicles fitted with power windows Octavia.
Two types of telephone systems are available. Either as a complete telephone system or as a telephone preinstallation.
On vehicles fitted with telephone pre-installation there is the possibility later to retrofit mobile phones (portables).
Mobile phones always require their own operating electronics, a so-called interface box, for operation in KODA
vehicles. This creates the link between the mobile phone and the components installed in the vehicle by means of a
standardised VDA plug connection. The standard telephone from KODA is connected to this VDA plug connection
via a special interface box. Whatever type of interface box can be used for the telephones of other manufacturers,
determine from the particular telephone manufacturer. Interface boxes without a VDA connector require an
appropriate adapter (available e.g. from the company Votex).
An overview of the possible versions is presented in the next few pages.

Convenience coding
On radio systems as of MY01, the function for convenience coding can be used (not valid for
vehicles with 1.4/44 kW and 1.6/55 kW engines). It is the function for the radio system and
the dash panel insert, whereby the dash panel insert and the radio system communicate with
each other and exchange information about their inner code.
The radio must only be coded when installed for the first time (or changed) Anchor.
Note
The entry of the code number must be confirmed when the dash panel insert is active
(terminal 15 - on).
For the following disconnections of the radio voltage supply (disconnecting the battery,
disconnecting the radio etc.) the radio must no longer be coded.
Note
For the mutual communication, the dash panel insert must be active (terminal 15 - on).
CAN databus
On Symphony radio sets (with cassette as of 05/01, with CD changer as of 11/02) the
communication can be activated and used via the CAN databus.
The CAN databus on radio sets (also known as infotainment CAN) serves for transmitting
information from the vehicle (usually from the dash panel insert) to the radio and vice versa.
On radio, this information is transmitted:
t information on multi-functional steering wheel
t

Information on data display from the display of the radio on the external display of the dash
panel insert

t Information on vehicle speed

t Information on the intensity of the display illumination
t Information on status terminal 15

General description
The Navigation System (also known as the Radio-Navigation System = RNS) combines the functions of a
navigation system with those of a high-performance RDS car radio.
The double DIN housing of the system contains
t an RDS radio
t a 5'' colour liquid crystal display
t a navigation system with GPS satellite receiver
t a CD-ROM drive for the navigation system
The aerial for the radio, telephone and navigation mode is linked to the navigation system by a plug
connection.
The radio functions can be enlarged by means of the connection facilities for a 6-CD changer.
A TV input on the rear of the housing makes it possible to use TV and video functions.
Fault finding
The Radio-Navigation System is equipped with self-diagnosis.
For fault finding, initiate self-diagnosis and interrogate the information stored with the vehicle system tester
- V.A.G 1552-.

Self-diagnosis of radio unit in RNS

HELP

The radio navigation system is equipped with an electronic anti-theft lock.

If the electronic anti-theft lock is activated, the red LED in the top right of the front panel flashes when the unit is
switched off and the ignition is off.
When the radio navigation system is switched on, the LED goes out and the system is operational.
The anti-theft lock is active and locks the system as soon as
t the voltage supply (terminal 30) drops below a certain voltage
t the fuse for the Radio-Navigation System has blown
and of course,
t if the battery (terminal 30) is disconnected (to carry out work on the vehicle).
Locking of the system by the electronic anti-theft lock is indicated by the SAFE text in the display when the unit is
switched on.
Cancelling the lock
It is only possible to re-start the system by entering the correct code number for the electronic anti-theft lock.
Obtain code number of unit.
Note
t The code number is stuck on together with the unit number on the radio card Operating instructions.
t

The radio card should not be kept in the vehicle for safety reasons. Determine the code number from the
customer, if it is not known.

Each unit has its own code number. If the radio navigation system is replaced the code number of the new unit
must also be used. The new code number must be advised to the customer.

Switch on the radio navigation system

The readout SAFE appears in the display. In addition the text Please enter a numerical code and the numerical
series 0000 appear.
Enter the code number stuck on the radio card by marking the digits on the selection field for letters and numbers
in sequence and confirming.
Note
Entering the first digit causes the string of numbers 0000 to be overwritten.
Confirm the code by pressing on the right-hand rotary knob/pushbutton.
The unit is enabled and is now operational.
If the code number has been correctly entered, the LED located at the top right of the unit must flash when the
ignition key is withdrawn. If the LED flashes, the Radio-Navigation System is operational and the electronic anti-theft
lock is activated.
If an incorrect code number has inadvertently been entered for cancelling the lock, SAFE appears in the display,
first of all as a flashing readout and then as a constant readout. It is only possible to repeat the procedure for
cancelling the electronic anti-theft lock twice.
If an incorrect code number is entered once again, the unit is blocked for about 1 hour.
It is only possible to carry out a further attempt to cancel the electronic anti-theft lock after this blocking period has
elapsed.
During the blocking period the unit must remain switched on and the ignition key must be left in the ignition lock.
After the blocking period has elapsed, the number of attempts in the display disappears and the electronic anti-theft
lock can be cancelled again as described above.

Self-diagnosis of the parking aid

General Instructions
The parking aid system measures the distance from the rear of the vehicle to an obstacle when reversing according
to the Echolot principle.
Four ultrasound sensors are installed in the rear bumper for this.
The actuation of the sensors is performed in the combined send-receive mode or only in the receive mode.
If a trailer is hitched up to the vehicle and the trailer socket is plugged in, the parking aid sensors are switched off.
Operation:
The parking aid consists of:
t Control unit for the parking aid -J446t Rear left parking aid sensor -G203t Centre rear left parking aid sensor -G204t Centre rear right parking aid sensor -G205t Rear right parking aid sensor -G206t The warning buzzer for the rear parking aid -H15After the ignition is switched on, a selftest is carried out for about one second.
The parking aid control unit is now permanently in operation, but the distance measurement system is not activated
until the reverse gear is engaged.
As soon as the parking aid is ready, a short signal sounds. (Delay of one second in the case of vehicles fitted with
automatic gearbox.)
If the parking aid control unit detects a fault in the system, a continuous signal sounds for 3 seconds.
Note
If a fault was detected in the park aid system, it is displayed on the vehicle system tester -V.A. G 1552- after a time
delay of two minutes.
The distance warning begins when reversing once the distance to an obstacle is about 1.50 m. The warning consists
of sound pulses with a duration of about 75 ms.
The intervals between the sound pulses become proportionally shorter as the distance to the obstacle decreases.
The sound pulses change into a continuous signal at a distance of less than 25 m (adaptation of the volume with V.A. G 1552- Chapter).
Special case: reversing along a wall

Initiating self-diagnosis of the parking aid

Connect vehicle system tester-V.A.G 1552- and select parking aid control unit.

Self diagnosis for the Xenon headlights with automatic regulation

(System Litronic 4.1)
General Instructions
The system contains a discharge lamp D2S with automatic regulation of the headlight height depending on the
angle of declination of the vehicle relative to the road surface.
The regulation of the headlight height works on the basis of data from two senders which are positioned on the
front and rear axle. All of the evaluation values for adjusting the stepper motors are carried out in the left
headlight (master) and after the connection of the electrical installation, the information is transferred to the right
headlight (slave).
If faults arise in the Litronic system 4.1 (discharge failure, ignition unit does not work, line interruption of senders,
front and rear sender defective) these faults are displayed by an orange warning light with the symbol of a lit light
bulb in the dash panel insert. (only for L&K version).

Note
All the possible faults which can be detected by the vehicle system tester -V.A.G 1552- are listed below

according to the 5-digit fault code.
t

Before replacing components found to be defective first check the wiring and plug connections to these
components as well as the earth cables according to the current flow diagrams.

After repair always interrogate the fault memory using the vehicle system tester -V.A.G 1552- and erase the
memory.

All static and sporadic faults are stored in the fault memory: A fault is detected as static if it exists for at least 2
t seconds. If the fault is then no longer present, it is stored as a sporadic (temporary) fault. /SP appears on the
right of the display.
t

After switching on the ignition, all the faults which exist are set to sporadic and are not stored as static faults
unless they continue to exist after completing the check.

If a sporadic fault no longer occurs during 50 driving cycles (ignition on for at least 5 minutes, road speed > 30
km/h), it is erased.

Diagnosis of the electronic immobiliser
Self-diagnosis of the 1st generation immobiliser
General Instructions:
Operation
The electronic immobiliser consists of:
t an immobiliser control unit
t an adapted engine control unit
t a warning light in the dash panel insert
t a reader coil on the ignition lock
t adapted ignition keys with electronic circuit (transponder)
The electronic immobiliser control unit is integrated in the dash panel insert, this means that the dash panel insert
must be replaced if the control unit is defective.
The immobiliser intervenes in the engine control via an adapted engine control unit.
The immobiliser reader coil reads out the response code of the transponder each time after switching the ignition
on.
The warning light briefly lights up when using an authorised vehicle key.
If an unauthorised vehicle key is used or in the event of a system fault, the warning light flashes continuously with
the ignition "On".
The electronic immobiliser features a comprehensive self-diagnosis. If faults occur in the system components, fault
codes are stored in the fault memory of the control unit. The faults can be detected with the vehicle system tester V.A.G 1552-, -V.A.G 1551- or - V.A.S 5051-.
Note
The following description only relates to the vehicle system tester -V.A.G 1552-. The use of the fault read-out scan
tool -V.A.G 1551- is similar except for specific deviations (e.g. different readouts in display, possibility of using a
printer etc.).
Notes for use or adaptation of the vehicle key
The engine only starts when using an authorised vehicle key, this means a vehicle key adapted to an immobiliser
control unit.
When adapting the vehicle keys Chapter all of the vehicle keys, as well as the spare keys, must be adapted to the
immobiliser control unit.
If new or additional vehicle keys are required, carry out the adaptation of the vehicle keys.
If for certain reasons, it is not possible to adapt all of the vehicle keys, e.g. keys are lost during a journey, the
customer must be informed that an adaptation of all the vehicle keys must subsequently be carried out.

Initiating self-diagnosis
Test requirements:
t Test the fuse on the basis of the current flow diagram for proper operation.
t Connect vehicle system tester - V.A.G 1552- Chapter.
t Switch off the ignition for approx. 30 s and then switch it on again.
Note
212

If no readout appears in the display, test the voltage supply of the vehicle system tester according to current
flow diagram.

t Additional operating instructions can be interrogated via the HELP button of the vehicle system tester.
t The button is used for moving forward in the program.
t An incorrect entry can be aborted with the key -C-.

serve to identify the mechanical locking.

Separate the right sticker -2- (with bar code),

remove it from the key fob of the new lock set
and destroy it.

Remove the remaining left sticker -1- (without

bar code) from the new key fob and affix it to
the key fob of the customer instead of the
previous old sticker.
