E63 with Knocking Sound
The last time there were several customers standing around the car they all heard it.
At that point the service advisor had to step up.
They will put the lifters in no Tuesday. I hope that is the problem will report back next week.[/quote]
Hi. Has the dealer replaced your lifters yet? and if so did the sound went away? how long did you have to leave your car there?
Dealerships can try and swap out the bucket tappets but it just comes back.
I have had MB replace motors over knocking pistons etc but the sounds never went away. The M119 in early forms had piston slap and so did my C36. Both had 2 motors installed and every time it never went away! So with that MB has learned some things dont ever get resolved and well its cheaper to just say so up front rather than replace parts until you go broke.
The new MB warranty line is.... that is normal. Normal oil consumption, normal knocking sounds, normal ball joint play, normal soft bushings etc.
If a tech finds your car has a failed bushing or an oil leak they cant by rule fix it or add a line to the ticket. They MUST wait for you to claim there is an issue. So really MB has tied the dealerships back at ever helping you keep the car maintained. If it is a true safety issue the shop foreman must approve the repair and add the line to the ticket.
Oh and seeping cam covers or front covers are not really repaired. The repair is only authorized IF the oil is actually dripping off the block. If not they wash it off and ship it!
Got to love MB!
Here is a good read on the 63 valve train.

Keep these cars for the term of the warranty and dump them
Thats my read for most cars however.

I went to two dealers; the first said it was "normal" and called it a motor pump sound(?) That was MB BH. At the second dealer, the shop foreman listened and heard it. He went over to a C63 and it kinda had the same sound. That was at W.I. Simonson.
It just sounds kinda whiney. I ran a CarFax on the car (I bought it new with 18 miles on it) and noticed right after delivery from the VPC, the dealer had replaced the drive belt tensioner pulley at 7 miles (MB South Bay.)
