Shock Absorber Replacement
General Information on Shock Absorber Variants
Do not replace both shock absorbers AIRmatic, ABC, ADS or adjustable
suspension strut if only one is defective. Only a component that has been
diagnosed to be faulty (damper or suspension strut) may be replaced!
Noise Inspection
Reason for the noise should be determined by driving each side of the vehicle
in turn over appropriate road surfacing or if possible by swapping over
the left and right component (damper or suspension strut). Before any
replacement is made loosen and re4orque the corresponding
damper/suspension strut first and check whether this resolves the noise
complaint.
Front
On the front suspension struts or dampers this need only be carried out on
the top bearing mounting.
Rear
Both the upper and the lower attachments for the rear suspension struts or
dampers must be loosened and then tightened again to the specified torque
with the vehicle in its ready-to-drive condition (i.e. the vehicle must be
standing on its wheels).
Section 2: Special considerations for different damping variants
1) Air suspension struts and dampers (Model 164, 166, 211, 212, 219, 220, 221
240, 251)
ADS suspension strut (Model 129, 210, 140)
Adjusting damper (Model 204, 207, 231)
Since it can be assumed that a new shock absorber installed in a high-mileage
vehicle would not harmonize with the used shock absorber and thus
impair ride comfort or vehicle dynamics, we recommend replacing these parts
in pairs after the component has traveled at least 80,000 km.
2) ABC suspension struts (Model 215, 216, 220, 221, 230) In contrast to the
air Or ADS suspension struts or conventional dampers, ABC suspension struts must
not be replaced in pairs at higher mileages (more than 80,000 km). The vehicle
body dampening is performed by active actuation of the plungers. These work
wear-free! Passive wheel damping by the shock absorber integrated in the
suspension strut plays a subordinate role.
3a) Conventional dampers (Model 164, 166, 168, 169, 171, 203, 204, 207, 209,
211, 212, 218, 219, 230, 245, 246, 251) Since it can be assumed that a new shock
absorber installed in a high-mileage vehicle would not harmonize with the used
shock absorber and thus impair ride comfort or vehicle dynamics, we recommend
replacing these parts in pairs after the component has traveled at least 80,000
km.
3b) Conventional dampers (Model 124, 129, 140, 163, 170, 201, 202, 208, 210,
461, 463) On these models diverse shock absorber variants are standardized in
the parts sector.
If dampers with new standardized part numbers are installed for replacement,
then conventional dampers must be replaced in pairs!
In the event of any complaints on parts that have already been replaced in
pairs, then the procedure as described in 3a should be followed.

Section 3: Deviating procedure
Information on additional deviating specifications for technical
modifications is available in EPC and TIPS The current documentation in
advanced
systems such as TIPS and EPC must always be followed! At this moment in time,
we would like to draw your attention to the special considerations
for models 204, 207 and 212.
