I am looking at an 08/00 (2001) S4 6spd. I have read the differences in the early 01s vs later 01-02s.

Big differences seem to be the revised oil lines, transmission, and f-hose. Are these things that should keep me from buying this car vs. later model?

Car has never been modified, has 36K miles, and the price is right. No sport package, no cold weather package.

I posted this to the B5 forum, but figured I would try asking some guys I had at least met.

Thanks

Mine is a 7/99 build. The only things I wish I had from the list are the new MAF sensor and longer warranty.


Differences that I know of:
1. New badge -- cosmetic, who cares

2. Revised turbo oil lines
IMO as long as you're anal retentive about letting the oil warm up before you push the car, the turbos will be OK. I drive mine pretty hard most of the time, but always keep an eye on the oil temp gauge before pushing it very hard. Turbos are quiet and I expect them to last a bit longer (45K miles now).

3. New MAF sensor (Hitachi vs Bosch)
The Bosch MAF sensor seems to be a common failure on the S4. New price is about $200. Dealer will replace it as if the car is under warranty and stock.

4. Removed f-hose
This has failed on some cars. MTM makes an upgraded one for a very reasonable price.

5. Upgraded TBB boot
The original boot fails on many cars. The upgraded part is only $10 or so. Not a big deal.

6. Different shifter mechanism
Is it better? Don't know.

7. Added ESP
Seems that the "good drivers" prefer not to have ESP as it can hinder the car's performance if you push it hard. However for those who are "average drivers" it can help when you make mistakes. Probably a good idea if you live somewhere where it snows a lot.

8. Steel front suspension parts (vs. aluminum)
Aluminum parts should be lighter. Audi probably went to steel to save money. No reports of bent suspension arms.

9. Different ECU version
Doesn't really matter unless you're in the market for a used ECU. Certain versions seem to be more numerous on the used market.

10. Warranty upgraded to 4 years (from 3)
My warranty was up last October. Although I don't expect anything to go wrong, it would have given me atleast another 2 free services from the dealer.

11. Stock tires different
Audi changed from RE040 to either Pirelli P6000 or Michelin Pilot Sport.
