N55 chain tensioner rattle?

Hi guys,

I'm happily driving my MY17 M2 for about a month now. I have put on 3,000km thus far, so I am well on the way of doing 35K km/year with it.

Absolutely love the thing, but I noticed a little noise inside the cabin that appears to come from the engine. I hear it when I am lifting the clutch and the car gently starts to roll or when I am just driving low speed in first or second gear. It sounds a little like a chain/tensioner/rattle. When picking up speed the exhaust/ASD trumps it so I don't know if it's present then.

Anybody know if this is normal? Factory warranty ends at the end of this month, so if something is up I would like to know beforehand. I want to ask owner's advice because Belgian dealers see 1 M2 for every 1000 of diesel cars. Therefore not really relying on their expert judgement if they send me home saying it's normal.

I used to have this on my 435i. Happened at ~45k KM, the sound is most apparent when taking off. I never got it fixed because my M2 arrived then.

Its most likely your dual mass flywheel. Mine does it as well and its louder than any other manual car I have ever owned. I think its just one of the quirks of the M2 with the manual transmission.

My car does this as well. It sounds like it's pretty normal for this transmission/flywheel combination.

Cool. I am starting to think it's also normal. I thought it might be the sound of direct injection.

Dual mass flywheel - clutch plate. Common rattle with the 6MT in M cars. Especially when you come-off load and declutch while rolling slowly

First noticed with my E90 M3 and again with my F82. Same with the F87
