ESP sensor unit -G419-, vehicles from my 02.02, removing and installing
The Sensor for transverse acceleration -G200-, the Sender for rotation rate -G202- and the Longitudinal acceleration sensor1) -G251- are assembled together in one housing on a new bracket, at the same place in the vehicle.
1) 4Motion vehicles with Haldex clutch only
- The ESP-sensor unit -G419- -1- is secured with a bracket on the steering column bearing bracket -a-.
When the ESP-sensor unit -G419- is replaced, a zero compensation of the sensor for transverse acceleration -G200-, the sender for rotation rate -G202, and the longitudinal acceleration sensor1) -G251- must be performed.

Removing
- Disconnect connector (arrow) from ESP-sensor unit -G419-
- Remove bolt -1- and remove ESP-sensor unit -G419-
- Remove nuts -a- from the ESP-sensor unit -G419-
- Remove ESP-sensor unit -G419-
Sharp shaking motions can destroy the Sensor for transverse acceleration -G200-, Sender for Rotation Rate -G202- and Longitudinal Acceleration Sensor 1)-G251-.
