Get an attorney. Jiffy Lube may very well be responsible if you have some credible evidence, such as repair order, the old filter, etc.

90K Service Interval ,,, and still going by kirby2010

I took the Audi in this week for its 90K service (2001 2.7T w/6-speed). The car runs like a top. I was thinking I'd drive another 90K since there really isn't much in it's class to choose from - especially with a manual. Then I saw the A5/S5. I can hardly wait until November.
 
Anyway, for those of you thinking about a 2001 or so I have to tell you that I have been pretty pleased. I bought it new February of 2001 and have had it in for service every 5000 miles for oil and tire rotation.

Whining noise when using the A/C by pcodeone

I have a 2002 A6 3.0 with 54000 miles. When I turn the ac on it makes a whining noise that seems to increase with the speed of the car until i get to a certain speed. When I get to higher speeds (40mph +). It only makes the noise when you are moving and It only does it in the auto mode. When i switch it to the economy mode the sound goes away but of course in the economy mode there is not much cool air coming out. Can anyone help?

sounds like the AC belt, when engaged is putting tension either on the compressor or on some idler pulley upon which the AC belt revolves. So I'd guess you have a noisy idler pulley bearing or AC compessor pulley bearing. Going on economy disengages the AC clutch and therefore the belt has no tension or pull on it, and this relaxes the noisy bearing.
 
Just a guess but it makes sense.

2001 A6 Avant Repair Questions by dpell

Just bought a used 2001 A6 Avant with 78,000 miles. The interior and exterior are like new and it has 4 new tires, battery, drive belts, and brakes. One problem I'm having is that when I get to 55-60 mph there is a slight vibration which feels like it's coming from the front end. The dealership which put the new tires on balanced them twice and said there should be no further problems but the vibration is still present. Could this be an alignment issue or a front end problem or even need to be balanced again? Also, when does the timing belt need to be changed and what is the average cost of doing the job. The engine is very smooth and quiet, how will I know it's time?

Thinking about purchasing a 2001 a6 2.7, or 1998 a6 2.8 (both quattro) by bcurrier

Hi Im a college student who has a 2 hour drive to school and a 1 hour round trip to work every day in the summer. The cars Im looking at both have around 100,000 miles on them, are for a good price, but from the repair costs I am seeing it looks as though all of my money earned in the summer would have to go towards repair costs should these cars break down. I realize this thread is attracting those specifically who have had problems with the car, but exactly how likely is it the car will break down?? please help me I have to start work soon and the car I am using for trade in cannot afford too many more miles.

I don't think anyone can tell you the likelihood of either car breaking down, as there is no way to predict this.
 
Common sense dictates that the older car may be more likely to have worn out parts than the one 3 years younger. If the younger car was mainly driven highway miles, then the high mileage may not be as "rough" on the engine. Some say turbo's break more than nonturbo cars, but the 2.7T has had all the kinks taken out over the last many years, so it is pretty reliable.
 
If you really want something that won't break, then get a Honda or Lexus, as they have statistically lower rates of breaking down than the Audi's in the time period you are looking at. Unfortunately, with those miles, neither car will qualify for extended warranties from anywhere.
 
OTOH, the Audi's are just more fun to drive and look so nice. My preference is the 2.7 as it is a very fast engine.
 
Good luck with your decision.

Grinding/bumping noise - 2005 A6 quattro by erickpl
May 31, 2007 (4:44 am)

When turning at a slow speed with the steering at or near full lock, 2005 A6 3.2 with quattro makes a grinding noise, and a bad vibration is felt throughout the vehicle. New tires did not help the problem, as the dealer thought (needed em anyway).
 
I'm suspecting an issue with the front differential or hub assemblies out near the wheels, but haven't heard anything about that. I would suspect the steering pump, but it happens when the car is moving, not when it is sitting still.
 
Any ideas? Dealer is stumped and vehicle owner is getting rather miffed about this vehicle.

Do you feel this vibration in your hands, through the steering wheel?
 
Can you increase or decrease the vibration slightly by small adjustments in the steering wheel (turning slightly one way or the other?)
 
If yes to one or both, I'd say steering pump.
 
If no, then possibly it is a front diff issue after all, if the tire clearances and stops have been checked and if there is no interference with body cladding, shields, etc.
