I will go for 90K service. What Do I need to do. Here is the list of things I will do:

Timing Belt/Watter Pump, Tensioner
Standard Check up
Oil/Oil FIlter
Serpantine Belt (?)
Brake flush
Thermostat (?)

Do I need to do all these Items?
Did I miss somethong?

I had searched for prev posts. Muhhamad mentioned transmission service and the diffirantial service. What is that? Do I need to do it?

Thanks

While you have it apart, replace the idler roller as well ... the follower is also in there but that's really excessive. I did timing belt, tensioner, idler.

Serpentine belt alone is ok ... the tensioner <i>could</i> go but it's really unlikely, and it wouldn't really cause any damage except the belt (not like a timing belt tensioner which is one of those chain-reaction failures).

Make sure you do the water pump gasket, and the thermostat o-ring, and .... COOLANT FLUSH.

I'd skip the brake flush until you actually replace the brakes, unless the fluid is over 2 years/50k old. It usually stays good for a long time, and when you flush it, it is clean.

Transmission service should be done at a 45k interval ... flush fluid plus replace filter.

Differential fluid flush on quattro models should be done every 45k as well, although I think that's one of the fluids that has a life longer than 45k. Check the seal while you're at that... and hope it isn't leaking!

I agree. (oops, with Muhammad) This is too high.

Yep, 90k is late for the timing belt... unless you're doing it every 45k.
