Yep (( but I found a cheap solution - racing diffs lsd conversion set. It's not the same lake lsd, but it works. So now I'm waiting this set for my 335d diff
I contacted these guys, yes it's a cheap solution but requires a lot of machine work, specially removing the welds from the pinion and re-welding it again.
i wasn't really happy about it, but if you're going to do it please document it or share with us as that would be very helpful.

Yep, my friend did this job. He has 335i Mt with big welded diff. He rewelded his diff. but installing lsd is more expensive

If you are US based I have a bolted 3.08 open diff I'm ready to sell. The ratio is a bit high for our transmission and turbo setup. But, boy, does it rolls through the gears quickly!

It was my demo unit to test the theory around gearing causing issues with MDCT programming. It came out of a high mileage car, so I'd replace bearings and seals if anyone wants it to install an lsd in it.

Thanks to everyone's previous efforts, I just completed the DCT with M3 GTS flash swap on my 2010 auto 335i. I'm using the MFactory lightweight flywheel, M3 diff and axles with carbon fiber driveshaft. Everything was pretty straight forward. I did have some issues with another install of ncsexpert that I thought I removed. Ncexpert and NCS Dummy were looking at two different work folders. I had to swap pin 8 of x6031 to pin 10 on the trans harness for it to correctly communicate P/N position.
I only swapped the DCT, GWS, center console with drivelogic switch so far. Coded Kombi, DSC, JBBF and CAS. I have all 6 modes of drivelogic in manual mode. I have some tuning issues to work out before I can run it hard but shifts great through all gears at mid and part throttle. I looked up the SZL and I believe the one currently in the car will allow adjustable launch control. I'll verify in the next few days. Again, thanks for the efforts of everyone involved in this project! Feels like a new car!!
I bought a 335is Harness is there any re pin required ?? I thought it’s just plug and play for the trans harness
