Anyone changed dct dual mass flywheel?

andrei.m4 · 08-16-2020, 01:30 PM

Recently my car have a lot of sounds inside transmission and i think flywheel have wear. Anyone experienced that? Clutch working without slipping problems.
Is a lot of play from engine braking and pressing gas, low gears not smooth, and recently a little vibration started in high gears at 2000-2500rpm while pressing the gas.

I saw a few videos with n55 and n54 dct flywheel fail and it sounds like my transmission sounds.
135.000km f82 15’
I am stage2 and even with toyo r888r in the back my clutch not slip, car run great in full gas.

Mine just failed as well. Looking for aftermarket options too.

My father has this same problem with his DCT M4 (mine is a 6MT) and he almost lost his mind trying to figure out what it was. How much does the flywheel cost from BMW directly?

Is it common for the flywheel to fail prematurely under e85 or upgraded turbos?

Might be. Mine died on the track after using an ethanol tune. Chattered on clutch release after that. I have a Spec twin disk clutch/fly setup now as my remedy...works great, slow to get in lower gears though

Sorry to resurrect this thread, but what were the symptoms that led you to find your flywheel was damaged? I'm facing a bunch of intermittent vibrations I think can be attributed to a failing flywheel but want to compare experiences.
