Just started car for first time in over a week. Heard the sound when car was cold and around 1k rpm. Ugly sound. Got better after car warmed.

Did it just get better or did it go away after it warmed up?

Yes I have the LSD. I'm pretty sure the noise is always present when accelerating, its just that I can hear it only below 1.5k rpm. Going to take to a shop to check it out

It's gonna be under the car and external. If you raise it up you can access it. Then just google c63 or c class heat shield and try to locate it under the car. I'm at the shop now so I'll update when I have info

Good luck bro. Although if your mechanic is worth his salt, he probably would have found a loose heat shield the first time around. Theyre fairly big and my guy literally saw the problem within seconds. I don't want you going in and wasting money! I snapped a couple pics so lemme post tehm for you.

update:

took the car to MB.

They diagnosed it for a whole day and found:

-Diff seal leak
-Upper oil pan leak
-Tappets and cam lobes worn out (causing the tapping noise). they found this by opening up the valve covers and boroscoping a bit too.

They are replacing the cams, lifters, tappets, camshafts and resealing the diff and upper oil pan!

luckily i still have warranty on the car so after opening a technical case with MB canada, everything is being covered.


hugggggeeeeeee job!

mines the affaltarbach edition that were the last to be produced when they were clearing out all of the cars before the FL version. MY 2011. pulled the Data sheet and the engine is outside the affected head-bolts issue so i should be good for that

But it looks like the lifters and cams issue is still very much existent until 2013+

The warranty on the car is MB CPO extended warranty and is now Power train only since its got less than a year left.

I bought mine (2012 MY) from the owner who bought the CPO. If the CPO transfers over, then I'm going to take my car in to service for tapping noise too if they will replace my cams and tappers under warranty. Cheers.

it should transfer over as long as you bought it from the person who bought the warranty and didnt buy it from another non MB dealer.

also they have to look through all your records to make sure it transfer over and all.

and then they also charge $350 to transfer it over lol.

they said it really is in the very early stages and mine has a bit higher km too (103k km) so thats why they are doing it. my dealer is super nice though and i feel like most dealers wouldnt have done it even in my case.

but tbh, if there are no signs, they will not do anything and may charge your for diagnosing it

I bought it from a BMW dealership that the seller sold it to. The seller and I arranged it privately but did it through a dealership so he can have trade in tax savings on his new purchase. I guess that disqualifies me?

unfortunately yes. it is clearly stated in their fine print that if you purchase from not a private party, it disqualifies you from the warranty transfer.

but you could still make a case and try to have it transferred.

you could try tracking down the old owner and see if he will give you a bill of sale for a private sale? but then im not sure if you pay taxes on it again??
