[Biturbos4] Buying a 2000 S4

[Brent Henry]

I have put a down payment on a 2000 S4 today.  It has 170,000kms (or just over 100,000 miles), but appears to be in excellent condition... I gave it an extremely thorough review inside and out with a lengthy test drive.  I have also scheduled an appointment at the local Audi dealer to run a complete 300 point check on the car before I make my final decision.

I would like to hear some feedback on what to look out for in these cars, with regard to electrical or mechanical weakness for cars with this much mileage.

The only things that I noticed wrong with the car, was that the trip-computer display was a little scrambled (intermittent)...  I believe that this could be cured with an application of Stabilant-22 contact enhancer -- on all of the dash connections?  How easy is it to remove the dash?  Is there any procedures listed on the web somewhere?  The other thing was that some of the Climate Control button movements were a little sticky... I suspect spilled coffee from a poorly placed in-dash cup holder?

Thanks for any feedback that you can provide.
Brent Henry.
