Test manoeuvre for troubleshooting on ARS:
Test manoeuvre 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 manoeuvre:
-> Clicking noise from area of front passenger footwell or area of right floorpan
Test manoeuvre 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 manoeuvre 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).
