MODIFICATION NOTES

11.7.11 Value changed: Rear axle vehicle level Model 204.0/2/3 except AMG, 4MATIC with code 483, 486 *BE40.20-P-1001-03P 
INSPECT Checking     
1 Carry out preconditions and tests for vehicle level measurement   AR40.00-P-0202A 
2 Clean measuring points IMPORTANT This prevents any measuring errors.  
3 Mount measuring sensor (086a) on cross strut (17) and read off vehicle level on inclinometer (086) NOTES The measurement sensor connecting cable (086b) must face towards the vehicle center. Otherwise the measurement will be inaccurate.
IMPORTANT Measure vehicle level at
  • Measuring point 1 (left front) and
  • measuring point 2 (right front) and store measured values.

Model 204 except 204.08/09/28/29/9 with old cross strut (17):
Mount the measuring sensor (086a) between the cast-in humps (arrows).
Model 204 except 204.08/09/28/29/9 with new cross strut (17b), model 172, 207:
In order to prevent the measuring sensor (086a) on the cross strut (17b) and therefore an erroneous measurement, the measuring sensor (086a) must be mounted between the cast-in humps (arrows) and pressed towards the wheel. The measuring sensor (086a) must contact the outboard humps (arrow).		  
    Model 204, 207 *BE40.20-P-1001-02P 
     
REFER TO COMPONENT MODIFICATIONS Cross strut (17b) changed Model 204 except 204.08/09/28/29/9. BT33.15-P-0050-01CW
4 Mount the measuring sensor (086a) on rear axle shaft (65) and read off vehicle level on the inclinometer (086) NOTES The measurement sensor connecting cable (086b) must face towards the vehicle center. Otherwise the measurement will be inaccurate.
IMPORTANT Measure vehicle level at
  • Measuring point 3 (left front) and
  • measuring point 4 (right front) and store measured values.
  
    Model 204, 207 *BE40.20-P-1001-03P 
5 Check the maximum permissible difference in vehicle level between the left and right side of the vehicle IMPORTANT The specified test tolerance applies only when checking the vehicle level but not for calibration.
If the vehicle level at the front or rear axle is out of tolerance, the springs and spring-rubber mounts must be checked for signs of wear and damage.
Permissible difference in vehicle level at front axle between right and left sides of the vehicle:		  
    Model 204, 207 *BE40.20-P-1002-02P 
    Permissible difference in vehicle level at rear axle between right and left sides of the vehicle:  
    Model 204, 207 *BE40.20-P-1002-03P 
6 Check and correct the adjustment of the headlamps Only if the vehicle level was adjusted.
