Shock Absorber Replacement
Section 1: General Information on Shock Abosorber Variants
Principle
Only the damaged component must be replaced.
Damage to a shock absorber or suspension strut does not automatically justify replacement of the
same component on the other side of the vehicle.
Check in case of noise before a repair
1. Determine the side causing the problem by driving with one side of the vehicle on a rough
road.
2. Unhook torsion bar linkage for test drive and check whether the noise complaint changes.
3. Release tension on shock absorber/suspension strut and tighten to ready-to-drive state.
4. If possible, left/right swap
Section 2: Special considerations for different damping variants
Conventional shock absorbers (MODEL 117, 164, 166, 168, 169, 171, 172, 176, 203, 204, 207,
209, 211, 212, 218, 219, 230, 245, 246, 251 and subsequent)
• Air suspension struts and dampers (MODEL 164, 166, 211, 212, 218, 219, 220, 221,
222, 240, 251)
• ADS suspension strut (MODEL 129, 210, 140)
• Adjustable dampers (MODEL 172, 204, 207, 231)

As of a component mileage of 93,000 miles, we recommend replacing in pairs, because the
damping characteristics of the old and new part may be different due to aging.
Conventional shock absorbers, old models (MODEL 124, 129, 140, 163, 170, 201, 202,
208,210,461,463)
For these models, any shock absorber variants may have been standardized in the parts
sector. If a new (standardized) part number is installed, the shock absorbers must be
replaced in pairs on these models.
ABC suspension struts (MODEL 215, 216, 220, 221, 222, 230, 231)
In contrast to other systems, ABC suspension struts do not have to be replaced in pairs even
with higher mileages.
Background: The vehicle body dampening is performed by active actuation of the plungers, which
operate on a wearfree basis! Passive wheel damping by the shock absorber integrated in the
suspension strut plays a subordinate role.
Section 3: Deviating procedure
Information on additional (possibly deviating) specifications due to technical modifications
is available in EPC and TIPS. The current documentation in advanced systems such as TIPS
and EPC must always be followed!
