How to remove and install the ESP G419 sensor

Important : the ESP sensor unit is sensitive to strong vibrations and shocks. Strong vibration and impact can damage it. If the ESP sensor unit falls on the floor, its perfect functioning is impossible, and re-installation of such a unit is prohibited.

 

 

On all car models, the ESP G419 sensor unit is installed under the left seat.

 

 

For the removal and installation procedure of the ESP G419 sensor, a torque wrench VAG 1410 should be used:

 

 

 

How to remove the ESP G419 sensor

1. Remove the left seat.

2. We bend the fastening tab of the mat.

3. Remove the footwell deflector.

4. Disconnect the connector.

5. Unscrew the nuts securing the sensor unit.

6. Remove the ESP G419-1 sensor unit in the upward direction.

 

 

 

How to install the ESP G419 sensor

1. We insert the ESP G419 sensor unit ( 1 ) from above to the mount. During the procedure, it is necessary to ensure a correct and accurate fit without skewing in the holder.

2. We tighten the nuts securing the sensor unit.

3. Connect the connector ( 1 ).

4. We install the deflector of the space for the legs.

5. We fix the mat with the tongue.

 

 

After replacing the ESP G419 sensor unit, it is necessary to carry out basic adjustment (calibration) of the following sensors:

• lateral acceleration sensor G200;
• longitudinal acceleration sensor G251.

 

 

 

For the basic setup procedure of these sensors, we need a VAS 5051B or VAS 5052 tester.

 

 

 

How to adjust G200 lateral acceleration sensor/G25 longitudinal acceleration sensor)

1. Select the following functions on the display in turn:

• Chassis
• Braking system
• 001 - Systems with self-diagnosis function
• 003 - Electronic braking system

2. Next, select the " Calibration " function.

3. Select the " Test the running gear and the entire ESP system " function.
