Checking

1

Carry out preconditions and tests for vehicle level measurement

AR40.00-P-0202A

2

Clean measuring points

 This prevents any measuring errors.

3

Mount measuring sensor (086a) on spring link between the cast-in humps and read off the vehicle level on the
inclinometer (86)

 The measuring sensor connecting cable (086b) must point towards the center of the vehicle, otherwise the measurement will be incorrect.

 Measure vehicle level at
 Measuring point 1 (left front) and
 measuring point 2 (right front) and store measured values.

Mount measuring sensor (086a) on rear axle shaft and read off vehicle level on the inclinometer (86)

 The measuring sensor connecting cable (086b) must point towards the center of the vehicle, otherwise the measurement will be incorrect.

 Measure vehicle level at
 Measuring point 3 (left rear) and
 measuring point 4 (right rear) and store measured values.

5

Check the maximum permissible difference in vehicle level between the left and right side of the vehicle

 The specified test tolerance applies only when checking the vehicle level but not for calibration.

6.1

Use STAR DIAGNOSIS to calibrate vehicle level

Only if the vehicle level is outside the test tolerance.



Connect STAR DIAGNOSIS and read out fault memory

 Do not adjust the vehicle level using the level sensor control rod.

Possible causes and remedies when the vehicle level is not OK after calibration:

 Attachment of level sensor is deformed.

 Connecting rod to torsion bar, spring control arm or wishbone has incorrect length.

 Attachment of connecting rod at torsion bar, spring control arm or wishbone is loose or bent.

7.1

Adjust headlamps

Only when vehicle level has been adjusted.



Check and correct headlamp adjustment
