Audi A4 Maintenance and Repair



  • whynot1whynot1 Posts: 3
    Has anyone ever had several electrical systems fail all at once? I have a 1998 A4 1.8T and I suddenly lost my windshield wipers, low beams, horn, turn signals, cabin fan blower, fog lights, rear defroster and outside air temp. indicator. There are also no blown fuses in the fuse box.

    Please let me know if you have ever heard of this.

    Just saw your interest in new tires. Up here in East Ohio, I'm also in need of new (all season) tires. My '03 1.8Q sport stock ContiSport Contact are in need of replacement at 20000. I'm thinking of getting the ContiExtreme Contacts. They're ultra high performance all season tires. I did like the OEM high performance summer tires, but I need better winter traction. I'm hoping to have better winter traction, less wear, but with minimal performance loss. Let me know what you come up with, or if you have better suggestions. Thanks!
  • An Edmunds search on "contiextreme" shows generally positive comments on that tire, including winter traction. Of course, just like the comments at, there are differing opinions.
  • I recently bought a 2000 a4 quattro (b6) 2.8L v6 with 35000 miles on it. I've put an additional 3000 miles on it and so far the check engine light has come on, along with the brake pad wear alert. At 38000 miles replacing the brake pads seems standard enough and my vagcomm software is showing that I need a new vaccuum hose for my intake (something that seems to be a recurring problem, at least for the 2000 and 2001 models). Other than that, I haven't had any problems with it and it's been riding like a dream. I plan on replacing the timing belt and tensioner, water pump and some other belts at 60k miles, which most people should. I'm concerned however from everyone else's posts as to problems they've had and I'm wondering if I should be expecting any problems in the near future? I hear a lot about the 1.8T, but not too many people are saying anything about/actually having problems with the 2.8. Also, too many posts from people who can't take care of their cars..someone actually complaining that their engine died after driving 20 miles with their oil light on...seriously...

    I have an 98 A4 2.8 and last night that same thing happened to me (I suddenly lost my windshield wipers, low beams, horn, turn signals, cabin fan blower, fog lights, rear defroster and outside air temp. indicator. There are also no blown fuses in the fuse box.)
    I checked all the fuses in freezing cold snow, didn't find anything wrong. I had to wait until the sun came out so I could drive home. Have you found out what the problem is. Please let me know I really don't know what else to do.
  • Hi I have a 1998 a4 2.8 the secondary air injection pump cycles after the car is turned off and causes the battery to go dead I think it might be the relay but I can't find it. does anyboudy know where I should look. I looked under the dash and hood. Or has anybody had similar problem and have any other ideas

    I have an Audi A4 2004. The automatic transmission lights on the dash ( shift positions) just started flashing. Anyone know what this means?

    I have an '02 A4 1.8T with Audi symphony audio system. Over the last year I have had sound go from one side to another (apparently a tweeter problem) that was repaired followed by poor reception in part of the FM band. I have had the radio stay on but not work requiring unplugging of the fuse and 3 beeps from the speakers occur intermittently when turning on the car. I have had the amp, the radio, and the FM antenna replaced but the system still does not sound like it used to or like the cars in the showroom. Any ideas?
  • whynot1whynot1 Posts: 3
    I talked with a audi tech. and he thought it may be an ignition switch (it cuts out high amp draw items prior to start) but I will not know for sure till this thursday (first avail. appointment).

    I will keep you updated and let you know what happens.

    Did you ever get your problem solved?

    I have a 2002 A4 (10,000 miles) with the same problem.

    Following is the message that I sent to the fellow who sold me the car:

    "Heater (and maybe air conditioner????).... since the beginning.

    With the Lexus, I set the AUTOMATIC CLIMATE CONTROL to "72" and never touch it again for the year....winter or summer.

    With the Audi and its dual controls, you set the temperatures (e.g. 69 and 67) and it runs until the car is so hot that you end up
    turning the unit off............when it gets too cold, you turn the unit on again......... and so on throughout your drive.

    Dealer (Don Rosen) said we tested it and it is working fine (diagnostic machine).

    AUDI USA said that if the dealer says it is ok.......then there is nothing that we can do."

    Thank you.

    Audi is the worst company to deal with Ive had nothing but problems with my 1996 a4, cant wait to get rid of it Audi wouldnt pay me back for the suspension problems I paid for out of my own pocket, even though they knew it was a problem A host of electrical problems too...I would NEVER buy another Audi.
  • lynnelynne Posts: 2
    Stay away from Audi A4, they are plagued with problems, and Audi is a horrible company to deal with. I paid for suspension and electrical problems out of my pocket before they were officially recalled items and Audi is refusing to reimburse me. Audi has been my worst nightmare. I would NEVER buy another Audi., it is a pretty and expensive piece of junk!
  • I have been considering an '06 A4 Avant, but the referenced posts raise a red flag. I wonder how much of the problems relate to specific dealers vs Audi regional and corporate issues. Also, prior to '04, CR ranked Audi with below average overall reliability.

    For the previous person's complaint, they had bought a 1996 A4. That was the very first year that Audi released the A4. There's a good chance that there will be problems/issues that arise with the first year models. That's been true for other auto manufacturers as well.

    When Audi redesigned the A4 in 2002, I had bought one of the first ones to arrive in the US. It too had it's share of issues because of being the first year of a newly designed car. Other A4s bought in late 2002 and beyond have had much higher quality and reliability than mine did. That's why I traded mine in for a 2004 model.

    In 2004, Audi AG went through some management changes up top. The new VP recognizes the concerns and issues around quality control and reliability. He is focusing his efforts to address all issues with the current lineup and to work on a process to further reduce issues in the future. This effort has been evident in the successful launch of the new A6.

    I would think the new A4 should also benefit from the work being done around quality control and be equally successful as the A6. The level of quality over the whole Audi line has improved over the years.

    For added peace of mind, it would also be a good idea to purchase Audi's extended warranty if you plan on keeping the car past the OEM warranty period. The cost isn't that much, and can save you the cost of repair (and parts) in the future.

    It was an ignition switch that caused all of the electrical problems. The total cost was about $300.00 for parts and labor. This was for the 1.8t I'm not sure of price for 2.8.

    I have a 98 A4 which the oil pressure light just went on. I go the same maintenance record story. I have all mine and bought it used. There is also a gap probably between 12,000 miles and 19,000. I now have only 24,000 miles on the car. I was told that if you put up a big enough stink with Audi corporate that I would get some action. The service bulletin was dated Aug 5, 04. Anyway, have you had any luck?

    I have a 2003 A4 1.8 and lately the moon roof has had a mind of its own. Two weeks ago, it partially opened by itself, then dropped back down. During the past week, when I pressed the switch to open it it wouldn't open unless I turned the knob to open the window all the way, closed it and then pressed the switch. It would then operate perfectly fine after that. I don't know if it's just because it hasn't been used all winter or what. The car has 41000 miles an has been fine other than this glitch. Any input would be appreciated

    hey guys this is my first post, well anyway i got my first audi a4, its a 96 2.8 and i got it from an insurance auction because it was in an accident and all i need is a fender and bumper, but anyways, i think this is the second accident its been in becuase the airbag light is on and the drivers horn doesnt work, so anyone know how to fix this problem? do i get a new airbag mod chip? where would i put it? how much? also the front passenger side door doesnt open from the inside any ideas how to get it to open? no child safety lock btw. thanks ahead of time
  • cyberpmgcyberpmg Posts: 83
    It may be a faulty switch or a loose wire connection that could be giving you problems. Since you're still under OEM warranty, have it checked out by the dealer (no cost to you) who can repair/replace it.
  • rsromanrsroman Posts: 2
    my stereo also doesnt work so i was thinking of putting a custom one in, but i hear that it devalues the price of the car, any ideas?
  • rusty812rusty812 Posts: 1
    I have a 2001 a4 quattro it has about 93000 miles. I been having trouble starting my car. Sometimes its starts fine but about twice a months it gives me trouble. I have to turn the ignition about 3 times to start it can i please get some info or is anyone having the same problems
  • mendlomendlo Posts: 1
    I have a '99 1.8T Quatro and am looking for a scan tool that would provide the best assortment of features (read Audi specific codes?) at a reasonable (less than $200) price. Any suggestions?
  • A 20 NOV 2004 report gives A4 the lowest rating for dynamic and overall seat/head restraint. Per IIHS: "Good geometry is a simple and necessary first step toward adequate protection and seats with bad geometry cannot begin to protect many tall occupants.". See
    I wonder what Audi is doing to obtain the "marginal", then "acceptable", and finally the "good" rating which other brands have obtained.

    Adui is by far one of the worst cars for long term reliability. Buy the extended warranty because after about 60K they start to fall apart like cheap toys. The only difference is your goanna pay a heavy price. Do some research, they are plagued with problems. Look at the incessant amount of service bulletins they produce each month. The 2.8 non turbo has been their best engine so far and even it is painful to keep going. I ditched my 98 A4 after having all kinds of mechanical problems after 60K. I foolishly bought a new model in 03 and it was in the shop more times than I care to think about. It’s gone and has been replaced by a much more reliable Lexus. All in all Audi is just a poorly built vehicle in a luxury car wrapper aka Volkswagen.
  • I bought a 1997 Audi A4 1.8T used, and have been driving it for about 3 months now... first time AUDI driver, and have just resently noticed that the pick up on my car has started to decrease. Usually I can hear my turbo start to intake air with a light whistling sound, but lately I hear nothing, along with the noticable boost loss. This makes me wonder if my turbo is damaged or broken. If any one knows of any signs to look for about this problem, or tips to check please let me know...

    Thanks all

    Check the bypass valve first - it is a lot less expensive and they can be prone to failure. If the valve is defective it could be causing the condition you describe.
