Operate the vehicle system tester by referring to the
read-out on the display:
Read out on display:
–Enter 00 for address word „Automatic test sequence“
and confirm with .
The automatic test sequence is carried out with address
word 00, i.e. the fault memory of all self-diagnosable sys-
tems in the vehicle is interrogated.
If a control unit responds with its identification, the display
will show the number of faults stored in the memory or
„No fault detected!“ Eventuell gespeicherte Fehler eines
Systems werden nacheinander angezeigt.
Any faults stored for one of the systems are displayed in
sequence.
If faults are stored, it is necessary to carry out a repair
measure. Displayed faults are to be entered.
–Switch off ignition.
The vehicle system tester -V.A.G 1552 - may have to re-
main connected for the exhaust emission test and for re-
setting the service interval display.
Resetting service interval display (SID)
QG0
If the due date of a service is reached, the service event
appears in the short journey counter below the speedom-
eter as a flashing display, after the ignition is switched on.
The service event also continues flashing for about 60
seconds after the engine is started.
The following displays are possible:
OIL - Oil change service
INSP - Inspection Service
The service event is shown on the indicator when the
service interval has been reached.
The service interval display should be adapted when car-
rying out the Delivery Inspection or during every Inspec-
tion Service.
The following intervals are set when adapting the service
interval display (SID):

02-8 Exhaust-emission Analy-
sis
The exhaust-emission analysis must be carried out ac-
cording to the relevant national legislation of the particu-
lar country.
Exhaust-Emission Analysis on Models
with Fuel Engines
Perform the following visual inspections and comply with
the setting conditions below before performing the ex-
haust-emission analysis:
Visual inspection
♦Lambda probes are connected
♦All vacuum hoses are connected
♦All wires of the activated charcoal filter system are
connected
♦All the electrical wires of the ignition and injection sys-
tem are connected
♦Hose for crankcase ventilation is connected
♦The exhaust system must be undamaged and tight
♦Catalyst must be undamaged
Test and setting conditions
•Perfect operation of the engine
•Perfect operation of the ignition system
•Intake system tight
•All electrical components are switched off (radiator fan
must not run during the test)
♦If any errors are noticed they must be repaired.
♦The idling speed, ignition point and CO content are
only measured as they cannot be adjusted.
♦The CO content is set to nominal value by the lambda
control. Faults in the lambda control are detected by
the self-diagnosis and stored in the fault memory.
♦When interrogating the fault memory (engine electron-
ics) all detected faults must be repaired and the fault
memory must be erased.
♦To prevent injury to persons and/or damage to the ig-
nition and injection system make sure the ignition is
switched off when disconnecting and connecting the
wires of the ignition system.
Connect the test equipment to the vehicle
To prevent industrial accidents or avoid causing damage
to the ignition system, pay attention to the following:

♦Disconnect and connect wires of the ignition system
(including high-voltage wires) when the ignition is
switched off.
–Connect the tester in compliance with the operating
instructions.
The exhaust gas probe must be fully inserted into the ex-
haust tailpipe (do not insert into the suction tube)!
–Start engine and run in idle.
–Measure idle speed and CO content.

All tubes and plug connections, which had been removed
or disconnected for the test and adjustment, must be re-
inserted or connected.
Technical data of the spark plugs Chapter 02-3.
Exhaust-Emission Analysis on Models
with Diesel Engines
♦When possible the test should be carried out immedi-
ately after the road test and also outdoors. If specific
reasons prevent this (weather conditions, excessive
noise in residential areas) the test may also be per-
formed in the workshop.
♦Secure the engine bonnet in the first stop while meas-
uring to reduce the noise.
Visual inspection
♦Hose for crankcase ventilation is connected
♦Fuel system and injection pump must be tight
♦The exhaust system must be undamaged and tight
♦All vacuum hoses are connected
Test and setting conditions
•Engine oil temperature at least 80 °C
•All electrical components disconnected
•No fault stored in the fault memory ⇒Chapter 02-6,
connect vehicle system tester and interrogate fault
memory
Correct detected faults before measuring (repair meas-
ure).
Connect the test equipment
–Connect the tester in compliance with the operating
instructions.
–Start engine, warm up to normal temperature and run
in idle.
–Perform the exhaust-emission analysis.
♦Activate and inspect auxiliary equipment such as e.g.
power steering, automatic gearbox or air conditioning
system. Check whether the engine continues to run
perfectly under this load.
♦All tubes and plug connections, which had been re-
moved or disconnected for the test and adjustment,
must be re-inserted or connected.

–As soon as the engine starts, press clutch and remove
gear to avoid driving into the towing vehicle.
Do not start the engine of vehicles fitted with an exhaust
catalyst by towing over a long distance as unburnt fuel
may get into the catalyst and burn there. This may result
in overheating and hence in the destruction of the cata-
lyst.
Perform a test drive
The following must be assessed within the scope of a test
drive according to the vehicle equipment and the availa-
ble possibilities (city/country, weather)
–Inspect engine for performance, misfiring, idling be-
haviour and acceleration.
–Foot and handbrake: Functional test (jerking, squeak-
ing, pulling to one side) ABS operation. Brake pedal-
idle travel: max.
1/3 of the idle travel.
–Inspect the lever position and smooth operation of the
gearshifts.
–Inspect the driving behaviour of the clutch as well as
the pedal force and smell.
–Inspect automatic gearbox: Selector lever position,
selector lever lock, shifting behaviour, display indica-
tion in dash panel insert.
–Inspect steering clearance of the vehicle standing on
its wheels, with engine running by turning the steering
wheel one way and then the other (wheels straight
ahead). There must be no play on the steering.
–Inspecting the sun roof operation.
–Pay attention to pulling and to the straigt ahead posi-
tion of the steering wheel during driving.
–Inspect the imbalance of the wheels, drive shafts and
propshafts.
–Inspecting functions: Heating, air conditioning, venti-
lation, instruments and warning lights, mirror adjust-
ment.
–Inspect engine, gearbox, axles, steering, brakes,
clutch, bodywork for abnormal noises
Raising the vehicle
Using a lift platform and a workshop jack
The vehicle must only be raised with a workshop jack in
the indicated jacking points -arrows-.
To avoid damage use a suitable rubber or wood insert.
