C43 Timing Chains?
Hey guys, whats the story with timing chains on the C43s I hear they are "lifetime"? Ive dealt with a snapped timing chain on a Benz V8 before (old 380 crapola) so just wondering about the C43 I have now with approx 90k on it.
Only symptoms of "sound" I hear now is when its cold, there is a tapping sound coming from the engine for about 3 mins and then it fades away as this "part" get its lubrication from the oil finally. Father says it could need a new timing chain tensioner and the chain is possibly slapping? Sounds iffy and scary.
Im going to the shop this weekend however want to know some opinions. Car is otherwise doing fine.
Thanks!

That noise is typically from the purge valve. On a CLK it's located up front near the ABS spider's nest. The purge valve is labeled MOT. I know I've posted photos of where it is before, but I have no idea what forum or even which website. A search on "MOT tapping" may reveal a photo.

Yes, can you please put in the instructions. I have a 17 C43 with 54k miles on it and local garage is telling me tensioner needs replaced and most likely timing chain. I have the same rattle at start last about 5 seconds. However I have the P0016 code as well. I'm trying to find more info on how to change the timing chain and specific tools needed. The Mercedes dealer is rough quoting $6k to $9k
