I love my C230K Coupe even after 5 years. However, after those years (only 36K miles!) in New York's rough bumpy road, it seems shock absorber is out of work (hard harsh ride). I am wondering how much the replacement of shock absorber cost at M-B dealers (including labor). Does anybody replaced shock @ M-B Dealers? Please advise me!

Also, recently I start to hear ratchet noisefrom the center of dashboard for30 secondswhen I start engine in cold (it stops approx. after one minute). Does anybodyknow the cause of this noise? (sound like old car's fuel pump sound? when start the engine). Please advese.

Thanks!
