  • erickplerickpl Posts: 2,735
    I had similar issues with my BMW. Window regulators failed due to the glass sticking to the rubber seal around the windows on hot days.

  • that sounds like it...thanks very much...will get it checked out...will let you know the cost here in colorado!

    I recently purchased a 2000 A6 2.8, W/88k. It sounds like an airplane when I use the A/C, dealer says its Audis are like that. I've heard similar noises from other Audis. Is this normal or is it a common problem. The air works fine and there is no loss of power, anyone info would be appreciated.

    I've changed my oil several times on my 2000 A6 2.7. I use a couple ramps and a creeper and have no problem. Just use a large headed flat screwdriver the loosen the screws for the belly pan. I think mine might not have all of the screws by the wheel wells but have never had a problem with it. Mine is being held on with 3 screws in the back and 2 in the front. A little tricky to line up sometimes. Can be done in under 45 mins.

    Please, please, please tell me you have found a cure for this? I have been researching this very same problem on the web for months! Have you also noticed the rev counter stopping, this induces the Gearbox 'Safe Mode' and the Brake, Oil & ABS lights? Your help would be worth a million dollars to me...

    Kind thanks

    I'm getting ready to buy a 2000 A6 2.8 and want to know what to expect regarding service issues moving forward. The car has 53,000 miles. Excellent condition. Never owned an Audi and don't know what to expect. Any advice.
  • Steve:
    Just be very sure that you have a thorough check of all transmission / undercarriage seals / gaskets. Leaking is a well recognized problem with the Audi A6 of the vintage you are considering. It cost me $2100 to have mine replaced (at 45,000 miles.) Then, in April of this year (49,000 miles...this is my second car), I was told that not ALL had been fixed and it would cost another $500 to replace the remaining ones. I wrote a pretty strong letter to the service manager of the agency who then advised me that Audi had come up with a new "share the cost" program. As a result, they did the "new" work and billed me $75 while they picked up the rest. Unfortunately, this plan was not retroactive to cover the $2100 I paid out last year.

    I drive a similar car, 2000 A6 2.7T w/ 93,000 miles. Same outside noise w/ the air running, however, only a bit from the inside cabin.

    Hello all.. I'll make this quick:

    I'm about to get into a mint 2002 A6 4.2 with low miles (40k). I test drove the thing, and I got that shimmy everyone had been griping about for years now (between 40-60mph). The dealer said "wheel balancing"... But after reading...

    I could not find a definitive "solution" to that problem.

    Before I really sign my life away and drive this potential headache :lemon: into my life, can one of you kind souls please clue me in to something I may have missed searching these boards vigorously?

    I've printed many posts from you guys, and hopefully that may help me, but did Audi ever come out with an "OFFICIAL" statement regarding the A6's that had the shimmy problem?

    You advice and input would be greatly appreciated.

    Kind regards,

    FKI (aka Perry)

    Glad to give one perspective. I don't do a lot of highway driving and on a recent trip I noticed I had a bit of a shimy. On my last service interval I had the tires balanced and rotated. Most of it disappeared. But the service rep told me I had been driving on under inflated tires. Not sure how he know this but it's certainly plausible. He went on to say that new tires would solve the problem. I haven't had this problem in the past but I went quite a while without keeping an eye on the air pressure. These were new tires at about 55K. (2001 2.7T w/6-speed, new in March 2001, now with 76K)

    Some of the roads are terrible here and I "try" to keep an eye on air pressure. My compressor gave out a year ago and I wasn't doing a very good job. After that service check I got a new compressor and am back to a every two or three week check as a precaution.

    For those who may be skeptical about the roads - I have about 20 miles of two lane country road to the office. Six stop signs, one stop light. Winter is hard on the roads and they really aren't designed for the traffic. Even at 30-40 mph the car takes a beating. A tire pressure gauge and small compressor are must-haves.

    At 40K you must be close to needing new tires. Balanced and properly inflated I think you'll be okay. If those are new tires it could be a different story.
  • marleybarrmarleybarr Posts: 334
    As far as brake "shimmy", I went through 4 sets of front factory rotors (on my 2000 A6) with no solution until installing a pair of drilled Zimmerman after market rotors, and they solved that problem.

    Also, rotating and balancing the tires seems to take of driving "shake" every other oil change, about 12,000 miles.
  • sfcharliesfcharlie Posts: 402
    Does 2006 A6 have the type of rotors which have to replaced whenever the brake pads are replaced?
  • duggan1duggan1 Posts: 2
    I have enjoyed my A6 but have had several problems that were not serious but very annoying. The latest problems are: 1. winshield washer fluid leaking occasionally-been in for service 3 times and they can't find problem.
    2. After sitting in sun for a period of time my radio will not work-CD player does-radio comes on 10minutes after start up.
    3. Finish on all door handles peels and has been peeling since the first year.
    Has anyone had these problems or knows of a solution?
  • bossfiftybossfifty Posts: 3
    I have an A6 4.2 2003
    For the washer, look closely at the assembly at the base where the pump connects. Mine failed there.
    Door handles.... not sure what year you have, but I understand that it was a product composition problem they fixed in most recent years, but older models we are "stuck"
    No issues with radio systems

    Thanks, I will have them check this
  • I have just gotten a 2006 A6 Quattro. I have Bluetooth capability but don't have the voice recognition package. The system works great when I'm driving and need to talk and listen to a call. But is there any way to transfer a call on the Bluetooth-connected phone from the car's audio system to the Bluetooth phone itself? If I'm driving and my wife wants to use the phone to call one of her friends, I'd rather not have to listen to the call (and she'd rather not have to crane her neck to talk into the in-car microphone). Any help would be appreciated.
  • Hi, I have a 2006 BMW X5 3.0i with a bluetooth package. My step mother has an 06 A6 like yours, and our bluetooth is virtually the same. So, with my experience the only way to avoid having my friend's/parents listen to my conversations is to go on my phone (razr V3, most motorollas are seteup this way) into 1.) the main menu, select settings 2.) Select Connections 3.) select bluetooth and 4.) (you must be in the car to do this with the phone connected, if you're connected there should be some name for your connection displayed on the phone, select it/highlight it) and select to disconect. Later when you want it back repeat the process however select connect in step 4. Hope this helps, only problem I've had doing this is sometimes after 10 minutes or so the phone reconnects itself to the bluetooth in my car. It's the best I can do haha.
  • Thanks for the reply, Christianm. I had figured that was an option - I just hoped it wasn't the only option.

    My wife has the Acura MDX with a handsfree-operated phone. All she has to do is say "Transfer" and the phone call goes onto her phone and off the sound system. I like that approach better. :-(

    the squicks that you heard indicate that the brake pads need replacing.
    the pads do not wear even because the caliper is stuck and the piston push against one pad only.
    if you had that problem in the front brakes you would feel it in the steering as the steering wheel will pull to one side during braking.
    get the shop to release the caliper and apply caliper grease.

    The check engine light has been on for about a month. Been to the dealer and the light came back on within a week. I suspect that it may be from the gas that I use which is BP.What gas do you use? Maybe switching gas will work. Other than the check engine light the car runs and performs great. Haven't had anywhere near the problems anyone else has had.
  • bumbiebumbie Posts: 18
    Has anyone had a problem with their A6 2005/2006 not wanting to turn over and start? It takes me 2 or 3 times to start my car, say 3 out of 5 times. The car grinds to start, almost like the battery is dead (it's not), and it sounds like the engine is barely running when I shift into reverse or drive. I was told the first time, it was the relay switch and it was replaced almost a month later, after I had to follow up about the part. My service guy apparently forgot to call me not thinking it is a problem your car not wanting to start in Arizona in July .
    Now two weeks later after the relay switch was replaced, it is back at the dealership with the same exact problem of not wanting to turn over and start. My car has been there since Friday and it is now Monday, I still have not heard a thing. Anyone have any suggestions? :(
  • g_henrysg_henrys Posts: 4
    If your battery has been disconnected then the auto up/down feature would be disabled. This goes for the inside switches as well as the auto up/down when you use the key to open or lock your door. To reset, use the inside switch to raise the driver's window all the way up. Release the switch. Then hold it in the same up position (even though the window is already closed) for a couple of seconds. That should do it. Good luck!

    I have had this car for 4 1/2 months it has 94,850 mi and this is what's happening:
    1. service insp light keeps blinking
    2. 3 beeps when start the car
    3. LCD bear visual, think it says MRND438 with a thermostat and water looking symbol
    4. today after not driving it for 7 weeks when I started it it had a orange circle with a motor and lightining rod in it blinking
    5. About 4 times since I bought it, while driving I've experienced a pause in the gear shifting only one time during each drive

    Can anyone give me some info on what's going on and what I should do? I don't have an owners manual and I'm afraid to take it to a repair shop or dealer without having some background info.

  • jrfivjrfiv Posts: 3
    I havn't had this exact problem, but mine doesn't want to start with the advance key - press start button and nothing happens. Dealer insists it is a "software problem" - neat.
    If I get in and press start and nothing happens, I can open the driver's door, close it again and then it will start.
    It is at dealer right now for this "software upgrade." I will let you know....
    Maybe you need this II software upgrade?
  • jrfivjrfiv Posts: 3
    I have had TONS of problems with this car. I leased it (thank goodness) but have had all kinds of trouble. Things like whistles in the doors (took dealer 9 tries to finally fix), new water pump, new brakes, 3 sets of new tires, new parking brake switch, 2 software upgrades, car not starting with advance key, grinding when starting.

    Has anyone else had problems with their car? I am on a first name basis with the service advisor. This is my first Audi is this a standard for this car? Everything seems to be very intermittent too - very hard to duplicate problems at dealer.


  • liferulesliferules Posts: 531
    Nope. I've had little to no problems with my A6. Seems like you have an anomaly. In fact, it appears the '05 and above Audi's have improved reliability from previous years, not worse.

    If you've truly had that many problems, then I suggest you look into lemmon laws :lemon: in your state and talk with the dealership GM about a buy-back.
  • jrfivjrfiv Posts: 3
    I tried that - the lemon laws in Texas are not very consumer oriented. I spoke with the GM and they didn't have a good solution - one was to put me in a 2006 for $100 more a month and reset lease....not quite what I had in mind. Going to pick up car now - been in shop all week.
  • klollyklolly Posts: 1
    For those of you that own this vehicle, I'd love to get a recap of your repairs. I bought it new in April 2001 and it has been in the shop 18 times, a few were for routine maintenance (10K, 20K, etc.) but each time, little things cropped up. My biggest problem appears to be brakes. At 17K miles they resurfaced the first time. Then at 24,500 they replaced pads & resurfaced again (just 6765 miles after the last work). Then I managed to get 12K miles before ANOTHER resurface, then 6325 miles later, resurface number FOUR. At 51,730 they finally replaced the rotors & pads. Now, 9703 miles later, I had to resurface the rears & replace pads only. That strikes me as odd, since I thought front brakes did most of the work. So brakes are a frequent issue, but I think I'm being ripped off. :mad:

    One change I am making - the dealership will no longer get my business (now that the warranty is gone). Other quality shops offer lifetime guarantees on brakes/pads, so I'm going to go that route next and see what happens.

    Now - I LOVE my car, even with it's dysfunction. In addition to brakes, they've replaced: wipers (3 times, okay, that's not really bad, ours dry out in Vegas), had 3 recalls, several issues with airbag light & engine light. Replaced faulty fuel sender, outer C V boots (twice), engine coolant sensor replaced (twice), replaced motor mounts (twice), replaced steering column, two batteries, d valve cover gaskets, cam seals, tensioner gasket, air conditioning control model, electronic fan, master window switch and rear window lockout switch, left front speaker has never worked right (but when in the shop they can never find the problem) and last but not least, my favorite, the hood strut.

    The hood strut is funny as the car was in the shop three times this last month & no one told me it wouldn't keep the hood up. I found out because the battery died & they came to jump me and we couldn't keep the hood up. So much for their walk-around inspections, including under the hood that they claim they do each time the car goes in. :surprise:

    In those last three visits, they also didn't notice the brake pads/rotors until the battery died - so between the battery, brakes & hood strut, $633! :sick:

    That's a lot of freaking problems for a car that goes in the shop regularly to keep it in good condition.

    Since October 2005, I've spent almost $4,000 on repairs and could have spent more had I not argued with the dealership about the repairs in October that included items that had been replaced less than a year prior - another $1,500 worth (the CV Boot). So, it was beneficial to contact Audi Customer Service to complain.

    Again, I love my car. :shades: It rides well, the interior is very durable for me (I love my leather), it still looks good, has convenience features such as the fold down seats. I am only posting all this info to hopefully help others & get some feedback to use on my next visit to get repairs.

    Even with all this, I'm keeping the car because I do believe it will last for a long time. It has great safety features (oh, it's been wrecked twice, not my fault, both drivers and passengers sides have been hit, passenger side was the worst, but we were pretty much okay). My daughter wants the car so before she gets it, I'll send it to a trusted shop for a very serious inspection.

    Hope all this info is helpful for everyone and feel free to email me if you have anything that I can use!

    And the new Audi's are really cool - next time, I might lease, which gets me out before things really go bad.

  • new2audi2new2audi2 Posts: 2
    Well, since I got no help from anyone online, I decided to go under the hood myself. I found oil very low and coolant very low. I filled them and drove for about 100 miles and the lights have gone out. It has been riding well since. I hope this helps someone else.

  • bumbiebumbie Posts: 18
    My last post was July 10th, I believe. I got the car back July 17 (they had it a week) and Audi service told me that they replaced the wrong relay switch in the ignition the previous time it was in - OK??? Picked it up, Audi service swore up and down it was fixed this time (since May 12, 2006 I have been dealing with this problem of my car not wanting to turn over and start, and when it does start, sounding very sluggish).

    So anyways, I notice two days after having the car back the same problem. I was praying it was just a flook, so I drove it a week, it happened about 7 times AGAIN.
    I called my Audi service guy July 24, brought it back in July 26 and it is now August 1st. My husband called late last Friday, since we did not hear from anyone at Audi and my service guy told my husband that they have no idea what is wrong and that they have to keep the car over the weekend. Once again no update call and no car.

    Audi can duplicate the problem (thank God over and over again), but they have never seen this problem before and have absolutely no idea what is wrong, thus no idea how to fix it.
    Be reassured everyone, Audi of N. America is having its data base searched ;) and the head technician is on it over at N. Scottsdale Audi! I was given that song and dance the last time it was in for a week.
    We are purposely not calling the dealership. We think it is better they appear unprofessional and incompetent and they do at this point if we have to pursue the :lemon:. We are going to contact the GM if it goes past the one week mark, which is tomorrow.

    Seriously, my car has been in and out of the shop 8 times since I bought it back in November of 2005, brand new. It was in once for the 5K service, 4 times for a loud traveling rattle in the dash, that was finally fixed by putting visible thick black foam against my windshield and the dashboard (I could have done that myself in retrospect), and now 3 times for the mystery ignition problem.
    I asked in my previous post if anyone might have a clue what could be the problem, but since Audi has no clue and this is supposedly the first time they have stumbled upon this ignition problem, I think is is safe to assume no one on this forum has a clue.

    If anyone has had a similar problem, I do not have advance key, please speak up, I would really really appreciate it :sick:.
