2012 C63 P31. Dreaded Ticking Noise. On Startup And When Turning Off.
0w40 is too thin and bleeds out of the lifters easier over time causing more lifter wear from increased cam to lifter clearance on start up. That is the tapping clicking noise you hear on start up. Lifters don't last forever and can become noisy over time.
Would you please show me where does AMG state to use 5W40 instead of the 0W40 in the M156?
If you've got lifter ticking noise, your lifters are worn. Period. The thicker oil is just going to mask the symptoms a little longer.
Again, I would really love to see a single MB-issued manual or document that says "use 5W40 instead of 0W40" in the M156.
as to the ticking after its off like others said and your tech said thats just the exhaust cooling off.

OP, you don't have headers do you? Because if you do you can hear unburnt petrol impacting the headers and making a clicking sound, it's prominent on large engines.

Like someone states, for some easy street driving, probably fine, but for anyone who drives hard like me, it's not suitable for consistent oil temps. I want the best I can give my car. Saying that lifters were still noisy when leaving the car a while with Mobil 1 0w40 so for this alone I wouldn't use it but each to there own I guess
Maybe the Mobil 1 "0" weight is too thin causing it to bleed off the lifters when sitting for a prolonged period?It is not 'thinner' than other 40 weights, in fact measured viscosity is actually 'thicker' than some, look at the data sheets
Viscosity 100 deg C
Mobil 1 0w40 13.5
Mobil 1 formula M 5w40 13.4
At 302 deg F the mobil 1 0w40 has a higher viscosity than the motul 8100 5w40
Most wear occurs at cold start-up so the 0 is better than the 5. They are the same when hot and perform equally no matter how 'hard' you drive the car. Lol

Afaik the only actually approved, not 'meets' or recommended oil is mobil 0w40?

The Best of Mercedes & AMG
Again - can you please post a single URL from the PL or elsewhere where an official AMG rep has said to use the 5W40 over the 0W40?

Should I bring it in for the warranty work or just don't worry about it. And drive it every day?
The tapping tick from the engine I also get but only when I beat on my car and park it and turn it off right away. If you let your car run for few mins after you beat on it and then turn it off there will be no ticking when you start it up. The ticking goes away. Ran in past few advisors and they both told me it's common and most likely due to a lifter being stuck. I am not worried about it.

It comes on and off only when the engine is reached maximum temperature.
Im attaching a video with the sound, I have uploaded it to dropbox.

Any suggestions/recommendations advice would be of maximum help.
Thanks a lot in advance.
The ticking in the video is the fuel injectors and perfectly normal. If you're talking about the "wowowo" sound that comes and goes, it could be any number of causes - but it is extrememly unlikely that you'll get an answer here. Ask in the relvant forums. Good luck.

Understood. I figured C63 section would have c63 motor question. I couldn't listen to vid at work. Disregard my post then.

Hahaha well I am unfortunately selling mine
so I don't have the willpower to argue in here. Plus I was wrong in this situation as I didn't even finish reading the post and thought I knew what I was talking about haha.
Thaaaank you
next step dreaded power steering whine.
