Engine replacement 2018 F80

[Binojp]

Not sure if anyone else had the same issue I had but I ended up getting my engine, turbo, oil cooler, flywheel, fuel pump, injectors alternator and aircon compressor replaced...all under warranty luckily!
All start with a clicking engine noise during cold starts and later during acceleration too
Thank you BMW Japan and BMW Nicole! All looking good so far!

There was actually a thread about this. Majority of the people were saying it was from the camshaft bolt not being torqued properly at the factory or something like that. My car had this ticking sound during cold starts and it just went away on its own.

Never heard of ticking noise issues other than maybe injectors as they get older but that’s normal

Well that was not true in these cases of other forum members, I have first hand knowledge with my 2018 F80 at the dealer for four weeks. My F80 only had 17k+ miles on it when the noise appeared. The had to open a PuMA case and my car received plenty of new parts under warranty. My 2018 M3 had a noisy lifter in cylinder 1, was the final conclusion by the service foreman. They isolated each cylinder and found the noise only occurred when cylinder 1 was operating. They replaced both VANOS units, lifters and rocker arms, reinstalled the exhaust camshaft and intermediate shafts, set timing and buttoned it up. My car sounded like a tractor and now it is whisper quiet. All the info is in the thread below.

According to the chief mechanic it was the damper that had to much free play. BMW is aware of this and the new engine had a revised version of the damper. Which is a relief. I'll get the part number of the new damper and post it later

Lots of times they’ll change part numbers but no actual change to the part that fixes something.
