Ok!
New window switch is in and the windows all go up and down with no intermittency and the remote windows work again, so success, though the zhong zhong quality of the switches isnt a perfect oem match.
The 034 dogbone insert was a breeze to install of course and provided some newfound crispness to the drive, thankfully. The dogbone and motor/trans mounts must be in dire need of upgrading by this point in this cars life. As all rubber bushings are... le sigh.
And the resonator delete certainly does add a fair amount of noise to the back end! So, can confirm: much bigger difference than in a gti. More overall noise, mostly more of a smooth boomy noise unfortunately, a BIT of drone but thats fine. Lots moar dsg farts, which at least makes the dsg as enjoyable as it can be, while i have a dsg.
So wins all around today!
