37 00... Inspection sheet

Test maneuvers for troubleshooting on ARS: 

Test maneuver 1: 

Drive with slow to medium-speed steering movements about the center position at approx. 20 km/h on a level  road surface.

Assessment of noise during test maneuver:

-> Clicking noise from area of front passenger footwell or area of right floorpan

Test maneuver 2: 

Drive straight ahead on a bumpy  road surface with one-sided, short-wave excitation (e.g tar spraying) at 30-50 km/h

-> Rattling noise

Test maneuver 3: 

Audible when stopped or during constant cornering on a level road surface -> engine speed at over 1000 RPM

-> Hissing in area of front passenger footwell

Check hydraulic lines: 

Hydraulic lines installed twisted: 

Check whether hydraulic lines are installed in holders twisted (when system is depressurized, hydraulic lines must be guided in holders virtually without elastic distortion of decoupling elements)

Line holders loose: 

Check whether line holders are correctly screwed and holder halves are correctly engaged

Line holders on hydraulic lines missing or fitted in incorrect position 

Check whether line holders are present in accordance with repair instruction and fitted in correct position

Check minimum distance in case of hydraulic clearance (insufficient clearance): 

First check minimum distance (A) = 3 mm between control line (1) and oscillating motor (2).

Then check control line (3) with minimum distance (B) = 8 mm to control line (1).

Refer to repair instruction. See 37 11 010 REMOVING AND INSTALLING/REPLACING FRONT ACTIVE STABILIZER 

Check screw connection: 

Check bolts at SPECIFIED TORQUE for secure seating. Specified torques are set out in the repair instruction.

Check play: 

Check ball joints for play

Check pressure line: 

Check Dynamic Drive pressure line between power steering pump and valve block to see if it is crushed or bent.
