Display group number 0932) is required to
perform a driving test Page 01
-284. It serves
to check the plausibility of the signals from the
steering angle sensor -G85-, Sensor for
transverse acceleration -G200- Sender for
Rotation Rate -G202- and sender 1 for brake
booster -G201-.
When the ABS control module (w/EDL) -J104- is
replaced, a zero compensation must be
performed for the following components:

Sensor for transverse acceleration -G200-.

Steering angle sensor -G85-.

Sender 1 for brake booster -G201-.

Longitudinal acceleration sensor -G251-.1)
When the individual sensors or sensors are
changed, a zero compensation must only be
carried out for the changed component.

1) For 4MOTION vehicles only

2) For ABS/EDL/ASR/ESP and
ABS/EDL/ASR/ESP 4MOTION only

Display group number 60: zero compensation
of steering angle sensor -G85-

Note:

All functions which could previously be
performed with V.A.G 1551 can now also be
carried out with the tester VAS 5051.

- Connect V.A.G 1551 scan tool and select
(address word 03) brake electronics control
module with ignition switched on; Page 01
-

- Start engine.

- Carry out a short test drive over a flat and level
surface. Drive straight-ahead and not faster then
20 km/h (12.5 mph) and observe the following
points:

If the steering wheel is not in the centered
position when driving straight ahead, the
steering must be corrected within the
framework of an alignment check.

If the steering wheel is in the straight ahead
position during the test drive, stop the vehicle
while still driving straight ahead.

- Check specifications with help of function 08

Make sure steering wheel does not moved.
Do not turn ignition switch off!

First perform function 11 "Login procedure"

- Now perform test drive for maximum 50 seconds
at a speed of 15km/h...30km/h:

It must be driven so that no ABS, EDL, ASR or
ESP regulation is performed.

Make a turn with steering wheel turned at least
90 .
When the ABS warning lamp -K47- and ESP
warning lamp -K155- go out, the ESP driving
test has been successfully completed.

WARNING!

Always comply with road traffic regulations
and drive according to the traffic conditions.

Note:

If the ABS warning light -K47- does not go out,
then the ESP driving test has not been
performed correctly.

If the ABS warning light -K47- does not go out
and the ESP control lamp -K155- lights up
again, check DTC memory Page 01
