what do you mean "dump"?

Ali_E55

mine has the same. it is the S/C engaging.

tbal

lol I thought you were talking about exhaust dumps (cut outs)

03'55AMG

id assume you mean the s/c clutch engaging. if you want, take it to the dealer and have the replace it, the new ones dont chirp

It's not the sc I dont think so at least but it sounds like the rear End

A small thump is what you meant?
Have you checked your rear subframe bolts?

black05scamg

No I did not will do thank you

Rear sub frame detachment is starting to become more common as these cars age.... the incredibly high torque the E55s put down doesn't help either

if it was changed before there was an issue, I don't think it would be an issue. Correct me if I am wrong.

Ali_E55

do u mean by the dump, say u give it a WOT and u feel and hear something knocked in the rear, like a hammer hits a metal ?? or even when just giving it a slight acceleration the hammer in the rear is felt !!!

this happens to me if i am cruising and the S/C in engaged a feel a hit in the back of the car. either WOT or non WOT.

can someone help me !!

thanks
