This is getting interesting. Why Audi stopped selling repair kits? Is it
because:

a) the newer servos just can't be rebuilt (something is welded, press-fit
or glued together)
b) they didn't believe the monkey lads at the dealerships could do this
properly (just like it happened with hydraulic pumps)
c) they didn't feel like selling $15 repair kit when they can sell you $400
servo (typical Audi attitude)

I guess that since the guys at Griffiths do rebuild servos for 5K cars and
require core exchange, it's either b or c.

I think I'll try to find a used servo and then see if I can rebuild the old
one from my car. If I were to buy seals - how do I tell if they are OK to
work with Pentosin?
