I have a 1998 A4 1.8T Quattro and I have 91,500 miles on it. I was wondering when my next major tuneup was due. I was wondering if it was 100,000 miles or what. Do I need to change the timing belt, any hoses, or anything else major besides normal stuff like oil, plugs, wires, air and oil filters. I was just wondering if Audi required any changing of any parts even though the car runs great. If anyone knows of this let me know. Thanks.

 

Yes you do.

 

Usually when you hit that high mileage its necessary to give the timing belt/water pump a change.

 

I'm surprized your motor hasn't **** itself yet.

 

Fuel injected engines dont technically get "tune ups." Tune ups refer to adjusting air/fuel mixtures as with carburated engines. All you need to worry about is regular routine stuff like spark plugs, fluids, belts, etc. If you get engine mods that require things the use of mbc's, afpr's, lemi,standalone fuel management, etc. then you will be "tuning" by adjusting those things till the engine runs right.
