My OEM clutch on my '17 Autobahn started to slip a few weeks after I flashed the EQT Stage 1 OTS, so I replaced it with the DIY TT-RS clutch thanks to this thread. Bought everything (TT-RS PP, TDI clutch, MK7 GTI FW, TOB, RMS plus VW sealant, and replaced all stretch bolts) from FCP Euro for the lifetime replacement and the total came out to $1070+tax. So far I'm really happy with the setup but I'm only ~250 mi on the break-in period.
A few things that would have saved me time that I didn't see mentioned for those with the VAQ diff and stock downpipe:
-I'd go in this order for removal: remove dogbone mount, remove downpipe, remove VAQ diff (or set aside, whichever you prefer). I could not make room for the VAQ without removing the downpipe.
-When putting everything back together, I'd install in the exact reverse order: VAQ diff, downpipe, dogbone mount, then finally install the axles. I saved the downpipe for last for no good reason, I didn't think the order would matter. But as a result, I spent a lot of time trying to squeeze it back in and also slowly turning wrenches a fraction of a turn at a time.
-If I ever have to do this job again (hopefully not), I'd buy a ratcheting wrench set. Working around the VAQ makes things pretty tight.
I'm really looking forward to finishing up the 500 mi break-in period. If it holds the power (which I expect it should with just a Stage 1 flash), the impact to NVH is basically just a slightly stiffer pedal. I'm grateful for those who posted, especially for confirming the part numbers!
