Audi A6 Maintenance and Repair



  • Any comments about the following since we have the same car.. HELP!

    I just purchased my first Audi 2001 2.8L 6cyl. 65,000 miles. These are my issues:
    1.Heat is coming out of the driver window side AC duct when the climate control is on anything other than LO
    2. AC is freezing on low but anything else seems warmer than the displayed temperature.
    3. When the AC is off. Light flow of heat is coming out of the AC ducts or around the edges of the ducts.
    4.Display between the odometer and speedometer has LED problem..(although every AUDI 01 I looked at had the same issue!)
    5. What's the beeping sound when I step on the gas? And how do I get it to stop!!!!!!!!!
    6. Why does the MPH in the dashboard display have a big "X" across the face?
    7. How do I shut off the 1MPH and MPH2 feature?

    That should be it for now!! Hope someone can clue me in!!

    It's not really clear from your post, but it seems like you are saying the dealer is blaming this problem solely on the fact that you have the CVT, as opposed to Tiptronic.

    If this is the case, then I can categorically say this explaination is ridiculous. My girlfriend has an '06 A4 with the CVT, and it is a wonderful car and transmission that does not display the behavior you describe. There are quite a few Audi dealerships in Southern California. Get yourself a second or third opinion.

    If you've never seen it, there is a great website at that ranks VW and Audi dealerships across the nation. The Los Angeles area, in particular, has some of the best and worst dealers in the U.S., so shop around before taking a line of bull.
  • I don't know or understand what you are asking in some of your questions but I'll take a stab at a few:

    1. The temperature setting on your climate control has nothing to do with the temp of the air leaving the vents. The degree of temp you set on the display is the temp you would like the air in the cabin to be. If you select auto, the climate control adjusts the fan speed/vents used/air temp to achieve your cabin temp setting. It is normal for only the side vents to pass air under certain settngs/conditions. In the winter for instance, you want the floor vents and the side dash vents to blow air. The side dash vents will keep your windows from fogging. You can manually close those vents if so inclined.
    2. See above.
    3. It is normal in most cars for some air to flow through the vents even when the fan is off. Most cars are designed to vent the cabin this way. You are probably feeling warm air off of the engine. I believe (like most cars) the intake is just in front of the wiper blades.
    4. I have a 2000 A6. Welcome to the club.
    5. I have no idea what beeping sound you are referring to. Take it to a shop.
    6. Don't know what you're talking about on this one either.
    7. I believe you set these with either the stick under the time and date clock (pull, push, twist, etc.) or with the windshield wiper stick.
  • I have a 2000 A6 2.8Q that I have always noticed to shift hard, particularly between 1st and 2nd / 2nd and 3rd. A few weeks ago, I test drove a new A6 3.2Q and noticed the exact same thing. I love both my car and the new A6 but can't stand having to concentrate on how I push the gas pedal everytime I accelerate from a stop in order to accelerate smoothly. I noticed in one of the more recent Car and Driver long term reviews of the A6(Sept, I believe) they make mention of this characteristic in an 05 A6. Do other Audi owners notice this? Is this why Audi puts a CVT in the two wheel drive models?
  • Does the CVT on 06 A6 behave any differently than the 03 A4. I just moved from an A4 to an A6. With my A4 I never used to feel the gear ratio changing. With the A6 when the car goes above 40 miles there is a discernable drop in rpm's from around 2400 to 1400-1600. Is this normal. Had no such experience in the A4. The dealership tells me this is what I should expect. Although I am not convinced.
  • Sorry to get into the discussion late. I have some background on a couple of these. I bought my 2.7T w/speed new March 2001.

    4 - I had the entire display assembly replaced under warranty at about 16K miles. The time and date would go out and come on at irregular intervals. No problem since.

    6 - There is a button on the bottom of the turn signal stalk. Push up on this button and you can toggle through the displays on the dashboard. Also a button at the end of the stalk. I'd have to run to the garage to remind myself what each does but you can play with them.

    7 - Very annoying, assume you're talking about the alarm when you are going over a pre-set speed. I didn't know the car had this until my wife and I were on the NJ Turnpike and it kept going off. Turns out it was factory (or dealer) set to 85 mph. Of course I had other problems when she figured out I was driving 85 mph since you can't tell sitting in the passenger seat. Anyway, use the little knobs on the dash - I think it's the one on the right.

    If you can't figure these last two out post a note and I'll get my manual out. BTW - I remain very happy with this car. It just went over 84K. I've semi-seriously looked at a new car but it's been problem free for a long time and is still a blast to drive. I would consider the A6 4.2 this time and I'm considering a test drive of the Q7.
  • guys:

    i'm considering buying a used A6 with 41k miles on it. it's supposed to be in excellent condition. a car locator found it for me. apparently, the audi dealership is selling it to a used car dealership, who in turn will sell it to me.

    i like the car, it has some power (even though it's the base model 2.7)

    I've two concerns:
    1. I'm afraid that the car will be a mechanical nightmare and unreliable...
    2. why are there so many middle men in this purchase. why can't i just buy it from the audi dealer???

    I'm not liking this auto locator deal too seems to be adding cost to my car.

    any opinions, things to watch for, etc - would be greatly appreciated....

    thanks in advance...

    Well the car locator isn't a licensed dealer so he can't sell it to you. I'm not sure why the dealer is passing the car onto a used car dealership---perhaps because he doesn't wish to have any liability with the car? That's a bit odd. Or perhaps the car locator gets a kickback from the second dealer but not from the first? Hard to say.

    Well look the car has to speak for itself regardless of how it's being sold to you. If I were you, I'd a) get a full inspection of the car from an independent shop and b) check on the retail values using Edmund's True Market Value system.

    Just go to and click on "used cars" and then click on "appraise" and you'll get some good numbers to rely on.

    Good luck with this!

  • thanks! i appreciate your input. actually, i cancelled on the deal. for two reasons: i think the finder is getting paid by the used car salesperson; but doesn't wish to disclose....

    2. I asked him for the VIN number of the car, so I can check it's history (with Audi of course). I want to see if it's still under the original warranty or not.

    Instead of giving me the VIN number, he said he is checking with the used car dealership to find out if the car has a five year, 50,000 mile warranty.

    I don't like this lack of disclosure. It doesn't seem to be rocket science to give me the VIN number - unless he doesn't want me to know what dealer he is getting the car from (to protect his business i guess).

    Do you know anything about the reliability of Audi A6's. Riverside Audi in New Jersey has a bunch (off lease). I plan to check them out this weekend.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,579
    My impression is that, over the years, they are pretty much "average" in reliability. I do think that once out of warranty, it would be an expensive car to repair...but to be fair, so would most comparable cars in that class.

  • thanks again...that makes good sense.
  • patpat Posts: 10,421
    You were smart to cancel - that all sounds very fishy. You are paying that locator one way or another and I believe you have a right to understand the process.

    And not giving you the VIN?? It goes without saying that that's ridiculous.

    Good luck in your search.
  • thank you...

    here's something to make you smile - I'm a certified public accountant and an Auditor. so i've become the biggest pain in the rear that the dealers have experienced. so some won't do business with me, and i annoy others. however, i've learned that you have to ask every question you have and if you don't get the answer, move on...

    You guys here on Edmunds are the best. i could never have learned so much without you all!!!

    ;) :)
  • btw,

    i believe the price i pay is loaded into the price (which would explain why i have secured prices at least $1,500k lower than what he gave me).

    He says that the quality of the dealer is most important. i agree, but i also believe that market price is market price. there shouldn't be so much disparity between the price he gets and the price i get.

    anyhooo - thanks! if anyone has fyi regarding Audi A6, I'd love to hear it!

    The Yogi Fan!

    Glad to be of service! ;)

    Keep us posted - check out the other discussions in the A6 group as well. You'll find some very enthusiastic owners who will be more than happy to help you.
  • My wife left the lights on her 97 A6 and the battery went dead. She had someone help her jump start it. When she got in the car the sun roof was open and now it won't close. Does anyone have a suggestion as to what the problem might be? I checked the breakers they are all good. When I turn the the sun roof knob to close the sun roof actually goes backwards a couple inches instead of sliding forward to the close position.
  • Has anyone else had the same problem? At 5200 miles my 2006 A6 3.2 cvt had the gas gauge register on empty after a fill up, the needle jumped to full after a couple of miles, this happened several times (needle on empty and then after a few miles registered somewhere else on the gauge) over the next week or so and I noticed the miles to gas tank estimated was erratic and registered anywhere from 320 to 620 no matter what speed I drove at, the gas gauge had a mind of its own and went down and then slowly up as I drove along the freeway, this all got worse and at 5,700 miles I took the car into the dealer, it came back "fixed" now the gas gauge registers full and stays there and the miles to empty still seems very high, the car has been back 3 times now and still registers full even after driving 80+ miles and the estimated miles left to empty tank registers from 555 to 610 ???
    I got the car back the 2nd time and the low washer light came on before I left the dealers lot!!! the windshield washer resorvior was completely full, they said the car was code as incorrectly??? The car also had a very noticeable gas fume odor, this was because whatever they did to try and fix the gas gauge when they emptied the tank they did not reseal it properly..... I'm about to take it back again......... fourth visit for the same problem..... has anyone else had similar problems??........ or can anyone give me advice on what I should do..... should I complain to Audi and mention the Lemon Law???......... The dealer has stated the codes were wrong and the factory software they used was also wrong and Audi had not informed them, they also said they had replaced the gas sensor....... took two days to get the part from New Jersey, then I got the BS that they could not duplicate the problem I was having??? The service Foreman even took the car home overnight to test it. I now have 6050 miles on the car. I like the car but not having this problem fixed I'm getting worried about future electronic problems etc, I have a 3 year lease so everything is covered by Audi but...... I'm paying the lease and driving a "basic" loaner rental! Which is not what I had expected at all :( .
  • Hi, I have the same model year A6, The phone cradle only fits certain make and model phone, check with the dealer or you can call Audi for the make and model phone, any blue tooth phone will work, however there is also a list of compatible blue tooth phones which will down load the names and numbers from the phones memory and will display them on the center dash. I just leave my Motorola V3 Razor on the center console slipped into the recess in from of the shifter, and receive and make calls from the controls on the steering wheel much like the controls for the cd and radio modes. I hope this helps. :)
  • I have the same 2006 A6 model, my car hesitates when in drive or reverse when you press the gas pedal but nothing like the same time delay as you describe........ I think the reply from the dealer is ridiculous, I would take it to another dealer or contact Audi directly and see what they say.
  • I have a 2006 A6 3.2 cvt with 6150 miles the problem started at 5300 miles. The gas gauge has hit empty 4 or 5 times, has been fixed 3 times then got stuck on full, fixed again at dealers, then screen washer light came up ..........another bad code??? now it has to do close to 100 miles before it moves off of full, miles left in tank indicates anywhere between 660 and 370 after 168 miles driven on a full tank, gas gauge is at 3/4.........its going back to the dealer tomorrow........ fix it time #4........they have installed a new sensor, told me the codes were wrong and reset them twice, told me they could not reproduce the problem the last time even thought the Mechanic Foreman took the car home overnight and put 68 miles on it in doing so.
  • I have a similar experience. 2006 A6 3.2. Gas gauge started to jump around: from half full to empty, from quarter full to half. I took it to the dealer who said it's a known problem -- they said it needed a software upgrade but the car smelled of gas for a week after. Then I noticed that the seat memory wasn't working correctly -- they fixed that. Then the gas gauge problem re-surfaced. They said they put in a new sensor but the next time I filled the tank I found a major gas leak. Turns out that they overtightened and cracked the cover to the tank. They fixed that a week ago but once again today the gas gauge jumped around.

    Does anyone know a permanent fix for this?

    I'm not sure I want to take it back, what will they break this time?
  • Hi. My 2000 A6 4.2 has the entire RH side of the car's exterior lights are dimmed and flashing funny. I have checked every light to make sure it is working and they all are. I thought it may be a bulb out?? I have read my owners manual and it is really vague.. Anyone have any suggestions?

    Many thanks in advance and Happy Holidays!

    A friend who has an 05 A6 had me looking at his car yesterday. It seems the front end makes a grinding noise when turning slowly, usually to the left, but it will do it ot the right too. He's tried rotating the tires, thinking it was a wear issue, but they are fine and it does it regardless of tires.

    Has anybody had issues with grinding/gear noises from the front end on their 05 A6? I'd like to be able to point him in the right direction. His dealer has said that noise is normal, yet it is only happening on a few A6's around here.

    Mine does the same thing on the first start of the day and only for the first few seconds. Dealer told me it was the car cleaning the brake rotors. I don't know if I believe it, but who knows.
  • jeqqjeqq Posts: 221
    I also had gas gauge issues. I didn't ask them what they did but from the service invoice it looks like they updated the software and also changed or cleaned the fuel sensors. All is well since then. Have your dealer redo it.
  • I had a EPC or EPS warning light come on while driving. Then the car would only idle no matter what I did with the gas. If I slammed it down with my foot ir would only idle and continue out 3 MPH and th RPM would not change. Has anyone else had this problem? Did it come back after the software update? Please let me know. Thanks, Dennis
  • I had this same problem and was told I need a software update. I do not feel my car is safe to drive after this happened. The dealer is trying to give it back to my with the all clear. This car has been in their shop for 30 days during the last 6 months. Please email me at

    I'm coming up on six years with my 2001 2.7T w/6-speed. I have about 86,500 miles. Although I'm not looking forward to the expense of the 90,000 service interval I think I'll have the car thoroughly gone over so I can drive it another three or four years, at least.

    I've had very few problems and none that have taken the car off the road. Everything was fixed at a normal service interval except for one problem about four years ago - I made an appointment and the dealer gave me a loaner. I get the oil changed every 5,000 miles, more frequently than the owners manual calls for. I always go to the dealer. I don't drive it on short errands where it won't fully warm up and I don't merge off the on-ramp at 90 mph unless the turbo temp indicator is up.

    I'm not opposed to a new car, I just like the six speed and the room in the A-6. I could afford a new car and I'm considering a Jeep Unlimited for in-and-around driving in order to prolong the life of my A-6.

    My opinion is this car is no more or less reliable than any other on the road. But it is a lot more fun to drive than most. It needs to be taken care of. Even Lexus and Camry have recalls. I cancelled my subscription to Consumer Reports a few years ago after what I believe was their erroneous assessment of Audi. Tonight's news further confirms that these people will print anything on the barest of facts.
