When you'll be getting the car back could you please ask them what exactly was causing the whining sound?
The list of replacement parts they ordered for your car is rather vast and I'm guessing it could be either the chain guides or the oil pump.
I really don't want the lower part of my engine to be disassembled for the oil pump to be removed

I always thought this sound was normal...I've heard it on E55s and C63s. Hell my own E63 makes this sound too but maybe a little quieter. I'll be surprised if it's anything actually bad.
BUT.....hey man...a fresh oil pump, cam gears and all installed the dealer can only be a nice thing for the motor that you have

The whining sound went down when they replaced all my idler pullies. It was still present, however.
There was another 'whirring' sound that was more concerning to the shop foreman. This is why they are pulling the motor and replacing said parts.
I will update everyone when I get the car back in my possession.

Got the car back today. All idler pulleys were replaced prior to engine being removed.
Engine components replaced:
The 'Whirring' sound is gone. The 'whining' sound, which was the main reason I brought the car in is still present. It has definitely toned down but is still there. I don't recall my PFL C63 making this sound... but hey guess I'll just have to live with it.
Engine components replaced:
- Oil pump
- Timing chain
- Timing chain gears and rails
- Head gasket

Now I only have to figure out whether my sound is "whining" or "whirring"
What does it feel like having so many brand new components in your M156?

on my car the whining was very high pitched, almost sounded like an electrical ballast noise for HIDs. But when I would press down on the intake manifold it would lessen. Turned out just about every intake manifold bolt was loose.... - snugged them all down and whining went away.

My car has a strange vibration issue which appears mostly when the engine is very hot (after driving in traffic). More of all I'm experiencing a grinding/scraping sound when driving slow.
The problem is currently narrowing down to the chain mechanism and oil pump. The car is not throwing any codes.

By "whirring" did you mean a grinding/scraping type of sound?

Did you get to the bottom of this in the end? I am in the same situation, but without the warranty. Next step are the 4 below. 2014 plate 46k miles on the clock. All advice welcome!

These threads suggest:
The M156 engine (63) does have a chain. but the intake and exhaust are gear driven, by a idler gear driven by the chain. it is a very cool set up. one other thing the engine oil pump makes a whine noise to.

Gear teeth wear down over time. They're also straight cut. The whine is normal.
EDIT: If someone here is replacing their perfectly fine 2014 adjusters, I'll pay for shipping to send them to me. Thanks!

I have the EXACT same sound. It is always there no matter whether the car is warmed up or not.
I had a machanic remove the serpentine belt and the whining was still present.
I guess it's something internal, perhaps the chain.
I'm still trying to figure out the cause.
BTW do you by chance have slight vibrations from the car, when standing on a red light in D mode? It feels as if the engine is misfiring from time to time (really it isn't).

this sounds like a normal noise to me. In fact in pretty much every car I've owned, 1st gear is a bit louder than the others, especially when you are over 50% revs
