I have to check...

Unless it's bad, it can only be heard when cold or warming up. The easiest place to hear it is actually at the passenger wheel. It's easier to hear once the high idle settles a bit but while the engine is still cold.

Narc that scumbag dealer out. With BBB and BMW. That’s unsat.

Thanks for the list, that’s wild tho.

She’s Finally Here! Valve Cover goes on today and injectors get dropped in. So excited to get my little monster back. Looks like it got a set of aftermarket valves too. Excited to see what we can do with this bad boy!

This will likely be my final post unless anyone has any other questions. I’ll try to check periodically.

Just bought a 2021 M2C and I dont remember this noise when I purchased it....but I thought something didnt sound right, googled and found this thread.

Would you mind listening to my video and tell me if this sounds very similar?
I have an 535i N55 so I know what injector tick sounds like, this isnt injector tick on this M2C...this is clearly a lifter or exhaust cam.

Have all dealer records and still under warranty for another year, so I'll drop it off if you think this sounds similar (give it 10mins to upload)

That sounds pretty similar to what I experienced. Does it do it when it’s warm and increase with engine speed? I could always hear it with the windows down driving past a fence and it kinda faded into engine noise around 3k RPM

Yes does it while warm too, after more searching I am pretty convinced I have the same issue going on with the cams. I'll drop it off at the dealer and tell them to reference the PUMA case #.

I wish you luck, hopefully no damage.
