Hello,
Airmatic suspension on my 12 cls550 4matic drops low after few hours being parked. This is after long time of cracklng noise over small bumps. I strongly suspect upper strut mount on air suspension has gone bad.
My question is, can I just have the upper strut mount replaced rather than the whole suspension assemly?
I am awaiting to hear from the shop and need to educatebmyself before paying up for a new suspension.

Thank you

 

same thing happen to me on 03-09-2017
i have 2010 S550 4matic

 

Unfortunately I had to replace the suspension. There was a company in Florida that would repair it and send it back to me for around $480. Also check Arnot and Ebay.
