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-.
