M4 flywheel for DCT 135i's

[AndyW]

Trying to nail down the correct part number to search for to get a used M2/3/4 flywheel for my 2012 135i DCT. The two numbers I have seen on different threads on other sites are 21212283829 and 21202283829, Any help or link to resources that can help me figure this out would be much appreciated. Thx!

Ooops, maybe I didn't do enough research when I bought one for my car. I have the 21 20 part number, but haven't installed it yet.

I'll be following this to see if anyone has any insight. If I had to guess, they are both compatible, one is just the next version of the part? Whether different processes used to make, or new jig or something.

It's wierd...if you type in 21202283829 at realoem it opens the 21212283829 part vice giving an error, but doesn't explicitly state it's an equivalent part. Both part numbers have used and new versions on ebay, but the 2120 is more prevalent (and cheaper!).

So I was looking into buying a flywheel myself for my 135, I called my local bmw dealer for info.
It looks like the 21202283829 got superseded to 21212283829 both will work!
I ended up purchasing the 21202283829

Awesome! Thx for confirming. How do you like it with the new flywheel?

I honestly bought it Thursday should be getting it sometimes next week or the week after. Once I receive it I'll take pictures and once I install it I'll let you know how it feels

Sounds like you got the part number figured out but just to give you another input, here are pictures of the one I bought, which came off of a 2018 M2.
