Hi Guys

I got my M2 lowered with H&R HAS kit and got a new damper at the left rear after an small accident.
They only replaced the rear left side and now we are 7 months later and its leaking again.

Went back to the dealer and gonna get a new one again. But what bothers me is that they only replace one instead of the whole axle.

I'd be impressed if they replaced it under warranty.
What's your ride height set at?

Lowered but not at his max

Excerpt from the BMW M2C repair manual

33 00 ...Information on replacing shock absorbers

Situation:

When a shock absorber is faulty on one side (leaking, noises, limit values exceeded on the shock tester), often both shock absorbers on the axle in question are replaced.

Effect:

This is not necessary for technical reasons and causes the manufacturer not to recognize the unnecessarily removed shock absorbers as defective parts. Unnecessarily high costs for the customer can be avoided by replacing the shock absorber on one side only.

Procedure:

If one shock absorber is damaged, it is only necessary to replace both shock absorbers when the car has driven in excess of 80 000 km.

Exception: On all M‐GmbH models, when a limit value is exceeded on one side, it is still necessary always to replace both shock absorbers on the relevant axle.

Okay, i have 75k km at this moment.
So it's recommended to switch both left and right side?

[n8dgr84]

Define "limit value"?
Is it related to mileage or some shock-specific wear limit?

The shock tester 'should' just be measuring the bump and rebound damping rather than extension and compression.

Time to take off the lowering springs since they kill shocks faster. Switch to coil overs.

You're lucky if the dealer is choosing to cover you under warranty with lowering springs.

Agreed, it's just common sense to replace both, warranty or not, especially at this point in their lifetime.

They replaced the broken damper but not the other one .
