Note:
For display group number 002 remember:
The reading of measured value blocks in display group number 002 must be undertaken when
driving off slowly. Then the ABS Control Module (w/EDL) -J104- will store the first usable
voltage signals provided by the speed sensors and display these as a fixed value in the
measured value block.

Display group number 40: switching off
longitudinal acceleration sensor -G251-

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

Display group 040 is necessary for shutting off
longitudinal acceleration sensor -G251- in order
to utilize the maximum engine performance for
a test, e.g. on a rolling road test bed. In
addition, the all wheel drive is shut off and the
vehicle behaves like a front wheel drive vehicle.

Switch ignition off and on again to reactivate the
longitudinal acceleration sensor -G251-.

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

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.

position during the test drive, stop the vehicle
while still driving straight ahead.

- 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
