The relay takes a speed input and turns it into a PWM signal to control the level of assist, if I don't find one I like its not that hard to design a better version.

I also found variable stiffness motor mounts on the same 2.0t... It seems that they have a solenoid that opens idle to reduce vibration and stiffens the response once you get on the throttle. Seemed kind of interesting.
So you're gonna try retrofitting those too?
I have Febi B5 S4 mounts and am not sure if I killed them with misfire vibration, which I later fixed (the misfires). I think the mounts are like $30/ea.
Either way, there seems to be some idle vibration (inline 4 engine is probably inherently unbalanced too, compared to a V8...that doesn't help), and idk how stiff the response is on throttle.

I know the idea behind rear diff carrier inserts is that they're supposed to help lock in place the drivetrain a bit; not sure if that would yield a good improvement here.
