Updated m2 DCT reliability thread
My family has had a couple of m5's and m6's with the dct transmission. They both had issues just once but nevertheless, an issue. All the dct threads are related to the older models with dct's, which brings me here. I am a prospective m2 buyer but would buy it in a dct. Has bmw done anything to improve this tranny in the last 5 years? Has the m2 dct been reliable ?

I believe m2 has the gen 3, most likely the last gen of it.
Gen 1 E9X MY2008-2010 Gen 2 E9X MY2011-MY2013 Gen 3 F8X MY2014-today No issues though. I never drove a gen 1 (I heard it's much jerkier). But comparing my m2 to e90 m3, I confirm gen3 is noticeably smoother, though it still gives you jerkiness in stop and go traffic, by sometimes not upshifting into 2nd gear even in comfort mode when should. You've got to get familiar with its behavior and when needed, work your throttle "tricking" it into upshifting, or simply manually does it.

I would check the reliability of the DCT in the f80 forums to see if gen 3 is likely to have issues. There have not been many posts (any at all?) on the M2 boards about a DCT issues, but the car is still pretty new. Maybe someone had fluid leaking? I can't recall anyone having major issues.

I just did a search on the F80 boards for DCT and clicked on every thread on the first two pages that have DCT in the title and a complaint.
Basically it was a bunch of "is it normal to hear this clunk sound" and "is it normal for it to be jerky 1-2" or similar. Then there were a couple DCT overheated once and went limp mode but never happened again, and the DCT stalled on me going quickly from R to D. That's pretty much what I found, no major issues in my search for f8x cars. |

I think they’re pretty solid in our cars.
My uncle has a Gen 1 and it definitely shifts slower and not as smooth or precise feeling. Also overheats on track, but he’s pushing 640hp with an ESS supercharger and other add ons. |
