[Biturbos4] Time for timing belt... what else?

[Chris Newbold]

I'm just rolling up on 80k miles on the S4 and am starting to collect
the parts for a timing belt job. To amortize the labor cost, I'm going
to take the shot-gun approach and replace all the wear items around
the front of the motor. Here's what I'm looking at so far:

  o timing belt
  o all timing belt tensioners/idler rollers
  o water pump
  o thermostat
  o serpentine accessory drive belt
  o all serpentine tensioners/idler rollers
  o all associated bolts, gaskets, fluids, etc.

So what am I missing? If this was your car, what else would you replace?

I'm going to take the opportunity to make a few gratuitous
improvements, too. I'll probably replace all the rubber bits in the
intake system with a silicone hose set, and perhaps I'll spring for an
RS4 oil cooler kit....
