Hi All,

Went today to look at a 2012 C63 coupe with 61,000 miles. Car checked out ok but I'm concerned about the usual camshaft / cam adjuster issues these car suffer from. I've taken a couple of video here of the engine at cold start up, cold idle and warm idle. Would really appreciate if someone could have a listen / watch and let me know if this car is suffering from any cam issues. There is a bit of ticking on idle but I'm not sure if this is normal on the M156.

First video is actual start. I think I can hear the cam adjuster rattle on start up but not sure.

Second video is idle after the cold start cycle is finished. There is a ticking but not sure if this is cam issue or just normal noise.

Again, any help would be great.
 
It has the camshaft adjuster rattle, not much but it will get worse over time. Otherwise it sounds totally normal.
 
Have you checked the oil level? My 156 is sensitive to oil level and runs louder if oil is low (albeit still between min and max).
 
Definitely camshaft adjusters as stated above. Best to replace the effected one asap. Depending on condition of adjuster, you can replace the plates with hardened ones available from 63motorsport. As long as the aviators are not scorched internally, it will be an easy mod 👍
 
+1for the above this was my M156
