2013 335is
Hey guys,

I did come across a few threads on the 335is DCT flywheel causing false knock on cylinder 5 & 6. Well I'm suffering with this issue. It happens at 6,000-6,200 rpm like 1 out of 5 pulls I do I get a cylinder #6 misfire. In order for it to not trigger the fault I have to shift below 6,000 rpm. I'm willing to upgrade my flywheel, but I can't decide on the M4 or the Mfactory. I like the idea that the M4 is OEM, but I'm also not sure if my flywheel is a 8 bolt or 6 bolt. It's a 2013 335is. I did reach out to Mfactory via email, but I would like some feedback on which would be the best option for me. I guess I'm looking for something that wouldn't chatter so much and it seems like the M4 is the better option, but again I'm hoping I have the 6 bolt so the flywheel bolts right up. I searched REALOEM and the dual clutch share the same part number with the M3/M4 based on my vin, but I still can't locate the flywheel.

Eh, I just ordered a M4 flywheel I found on eBay for $210. I couldn't pass on the price. Hopefully all goes well and fixes my issue before I start pushing out more serious power with the upgraded twins.

Any n54 after 01/2009 is a 6 bolt.
