E63 engine ticking
there is a rattle that occurs when the car hasn't been driven awhile and is only noticeable at ~30MPH. i swore it was coming from somewhere inside the car, but now am convinced it is from the engine.
of course i can't recreate at the dealer, because by the time i get there the car is warm.
is this most likely the camshaft issue??
thanks!

What motor do you have?
My M156 was ticking and dealer ended up replacing the lifters and the intermittent sound is apparently gone now. Take it in for service.

i'm not worried so much...but annoyed
this doesnt seem like "normal" engine noise
we'll see what the dealer says
i havent been thrilled with the service dept so i wanted to arm myself with at least some knowledge
thanks for the replies so far folks!

am i right to be disappointed with the build quality or is this the new normal?




You say it happens around 30 mph. Well, you have paddles to change gears while remaing at 30 mph. Down shift for higher rpms while holding the same 30mph. If sound does not change in pitch you can pretty much rule out the engine and lifters and such.
If the sound remains the same when shifting gears it is something else that is not likely engine or trans. Could be gravel in an axle as was mentioned, but this sounds a bit more rare than likely. I would then look at a bad wheel balance somehere first that "excites" the resonance that creates the sound, or it will be drive shaft or differential related.
The really good news is that it is brand new. You will get it fixed at no cost to you for sure.
Best of luck!
when i dropped it off, i spoke to the shop foreman. he said the ticking might be the purge valve? not sure this makes much sense since i only hear it when the engine isn't warm and at 30MPH.
i have 2 sets of wheels and i can hear the ticking on both sets so i don't think is the tire balance.

given your car is brand new, it shouldn't be these issues, since they are wear and tear items...

this was the dealer i purchased from so i assumed i would get better service. there is a dealer right down the street from my office. thinking of giving them a shot.
this is all quite annoying!
i can't seem to recreate it at the dealer either. really frustrating.
Their last suggest was they were submitting it to AMG for a response. I'm submitting the car for lemon law. Besides the ticking, the panoramic roof shade was an issue 4 times as well as the drivers side front window. Love the car, but at $100k I find all these issues to be unacceptable.
