I am seriousley interested in a used, 2004 audi a4 1.8T Quattro with the ultra sport package, and i was interested in peoples opinions about the reliability. this is really my only concern, because i heard from a friend that the 1.8T is a great engine IFF you PERFECTLY maintain it, and if you miss one oil change the engine can become very unreliable and expensive to replace. also, i think it is a little sluggish, having to tugg around a heavy car with a 4wd system so i was considering putting some type of a chip in from a reputable company used in one of car and driver's golf gti's. would this make the engine even more unreliable? thanks for any info and advice!

I love my 2001 A4 1.8T wagon (Avant) AND I have regularly invested about $2000 a year in maintenance/repairs since about 60K around 3 years old. I put about 20K miles/year on it and enjoy my commutes. You just need to make sure the following have been taken care of or you will pay for it. The former owner should have done this if he/she was a good owner...
 
full-synthetic oil changes every 6 months or 10K miles (Mobil 1 or BMW oil)
brakes (both front and back) BOTH pads & rotors replaced or you will have to do it.
Coolant flushed at least once
Brake oil flushed/replaced at least once (for a few extra $ this can be done during a brake pad replacement job).
New battery (make sure it is a more-expensive sealed type)
 
and ask if the fuel pump has been replaced (it goes about 100 - 120K, mine went right at 100K) as it vibrates loudly under the passenger seating area (the pump is attached to the fuel tank!).
 
Good luck - James

And I forgot to mention to check/replace ALL the critical rubber hoses as it gets very hot under the hood. Check on the coolant and ESPECIALLY the turbo-crankcase vacuum hoses. If these turbo-vacuum hoses leak, your turbo will not work and a engine check light goes off.

I had a 2001 GTI with the 1.8T, and a Neuspeed chip..Also tried the Revo flash for a short time. They both added lots of power, and made the car 100x more fun to drive. The only problem I had was with the clutch, it didn't seem to like the extra power and started to slip after about 30k miles. Also had a turbo-back exhaust system with high flow cat, N75 valve from a Audi TT, and Forge diverter valve. The 1.8Ts are very reliable, even with punishment!!

My advice for prospective buyers.
Lease/Purchase the car but DON'T keep it for longer than 2 years.
It's goes downhill from there. Better safe than sorry!

The factory warranty is 4 years 50k miles. You can buy Audi Care for $590 that takes car of all maintenace up to 50k. You can get a lot more than 2 years good use out of an A4.
