Tick tick tick after start up.
#26
It was a faulty lifter afterall, not a camshaft adjuster. Dealer replaced it free of charge and was Very apologetic! The noise did come back once on the morning startup, but then went away. Have not heard it since for 3 months! There should be a recall on these, just saying.

Thanks for the update Boris. Based on your knowledge of this issue, would you recommend I take my car to the dealer immediately? I don't know much about lifters and how this fault could affect the engine.

Based on dealer's reaction when they heard the noise and their willingness to replace the part I'd say take it to them ASAP and have them replace it. It is NOT normal and should be fixed. If there is inadequate oil distribution to the cylinders via the lifter that is causing them to make this noise, it is not OK to keep ignoring it.

I doubt they are the cause of your finicky oil temp readings.. I suspect that would be the oil temp sensor.
If you have bad lifters you will hear a TICK or CLICKING sound that revs in relation to the engine RPM.

I have the same problem and end up with a set of lifter and a worn cam replaced under the warranty. Should send it to the dealer as soon as possible.

May I ask 3 questions?
1) So, your car displayed the exact problem that is the subject of Mr. Chan's class action lawsuit against MB?
2) Did the dealer say any of the particulates from the worn cam moved and settled about your valvetrain?
3) Did the dealer tell you they replaced the worn cam with a new cam that is made of a different material than the one that wore prematurely?

Also to note, is that the longer the car sits between start ups the more likely you will get this sound.
I had it checked out by the service tech and said it was normal at start-up and should go away after a few minutes.... he also compared with 2 other C63's (because I was not convinced with his explanation...LOL) that were in for service the same week.... all did the same.
Ensuring that oil levels are topped up helps as well...

Really, a worn cam?

2) they show me the photo of the worn cam and hole in the lifter, they send in for the claim of parts
3) No, in Toronto all Dealers are owned by MB, they won't tell you anything to against them, right?

Regarding the Class action, I don't think much can be done, because in most cases the repair under the warranty and look like all these problems happened on the earlier production cars. Hopefully these problems do not come back.

So, when MB replaces the cams under warranty, the fear is that they are replacing the cams with the same cams.
This is what has been explained by those who have seen the cams in M156's from different model years--including current MY's.

A loud ticking is what I gather.
You guys got me all paranoid, I spent half an hour outside listening for ticks.
My car will tick for 1-2 seconds upon a cold start as the lifters fill with oil but after that i can barely hear any ticking, a very slight valve train noise but nothing like posted in some of those youtube videos where the lifters are ticking loudly.

But, if the ticking grows louder in proportion to the pressing of the accelerator, it is probably a good idea to go to the dealer.

My paranoia paid off. Other day I start the car, TICK TICK TICK. Sounds like a lifter. I recorded it on my phone. I don't really recall it ever making this noise before it was really noticeable and could be heard clearly from outside and inside the car. It increased and decreased with the RPM.
I let the car warm up, the noise was still the same, went around the block and hammered it to bring the oil pressure up and the ticking went away.
I couldn't reproduce the noise for the tech, but burned the video on a CD. They are replacing the cam tensioner's next week after the parts arrive. I explained that it sounded like a stuck lifter, but they said its too hard to determine from a video recording... Also going in for a left bank lean code which is the second time they are attempting to remedy the CEL.

Mine was built November 2008, but haven't really heard ticking since 10k miles. Now I'm at 31k running it hard...? I'll pay attention but all I hear are power steering and suspension noises from time to time
