Perform ESP road and system test (vehicles with ABS/TCS/ESP BOSCH 8.0)
The ESP road test is a plausibility test of the signals from the lateral acceleration sender -G200-, yaw rate sender -G202- (both senders in the ESP sensor unit -G419-) and the brake pressure sender 1 -G201- (in the hydraulic control unit).
The ESP road test should be performed after each replacement of the electrical components of the ESP system.
If the ESP road test is initiated, it can no longer be interrupted and must be performed.

–  Separate vehicle system tester - V.A.G 1552-.
–  Start the engine.
–  Depress the brake pedal forcefully until the ESP and TCS warning light -K155- goes out, at the same time the ABS warning light -K47- lights up.
–  Now carry out the ESP road test.
  WARNING
The rules of the road traffic regulations must always be given priority.
–  Drive a right or a left curve. Subsequently carry out a change of direction and drive a left or a right curve.
–  After cornering, drive straight ahead for a certain period of time.
  Note
t  A curve with a radius of 10 to 12 meters and a speed of 15 to 20 km/h must be driven in approx 4 seconds during cornering.
t  It must be driven in such a way, that no ABS, EDL, TCS or ESP control is activated.
t  If there are other traffic dependent driving manoeuvres between cornerings, they will have no influence on the ESP road test.
If the ABS warning light -K47- goes out, the ESP road and system test was successfully performed and ended, the system is OK.
If the ABS warning light -K47- does not go out, the ESP road and system test was not successfully performed.
–  Repeat ESP road and system test → Chapter.
If the ABS warning light -K47- and the ESP and TCS warning light -K155 - light up, there are faults in the system.
–  Interrogate the fault memory → Chapter.
