This one is useful too, he added helper springs to the top of the bolts I was adjusting. (He has lots of A8 tech videos on his youtube page)
EDIT* I checked the spring-pin buffers 8H0827249 on the boot and they do not appear adjustable, it seems they can be disabled by pushing the pin in and turning it or enabled by turning the pin until it pops back out. The outer buffer part won't turn. I did try turning them while the pins were out but the length and spring tension appeared to remain the same.
- am I missing a trick here?
It isn't a problem with the motor as I can here it turning and the clutch starts to slip too, but also the motor is really slowing too so I don't think the clutch has undue slip.
