Audi A4 Maintenance and Repair



  • bgs3bgs3 Posts: 1
    I am new to this website and am seeking information on transmission problems on A4s. How do I go about getting info on here pertinent to this? We need our 3rd transmission in 4 1/2 years, it has never worked smoothly (and we even had it repaired the week after we purchased the car brand new). Of course, Audi America and our dealer do not wish to pay for this now that it is off warranty. Based upon what I'm reading on other sites on the internet, this appears to be a chronic issue. Why hasn't there ever been a recall? Or an attempted class action lawsuit?

    Recalls are generally only for drastically safety -related issues.

    i already post my problem about the central locking system or the power locks. i did follow the message from rowlandi and still won't work. in the manual, i just checked all the fuses and they're all working and there's no more instructions how to fix a failure central locking system or the power locks. i already replaced the battery of the remote. this is a 1999 audi a4 quattro 6v 2.8l.
  • My 2008 A4 v6 has been sluggish in the morning and recently the "check engine light" came on. The car has just under 15k miles and received standard maintenance service at 5k and 10k miles. Dealership tells me it's misfiring on 2 points and that it appears to be carbon build up. Dealership was asked by Audi to take pictures--pictures!--and forward to them.

    We only put high octane (91 or 93) tier one gas (Shell, Chevron, Texaco) in the car. Any thoughts from anyone? Why would Audi need pictures?
  • First, are you certain that your dealer has performed the "standard maintenance" services? Audi dealers are know for "pencil whipping" the services to cut cost and labor while back billing Audi North America. Classic example is "Audi Air Filter Services" at 20k and 40k. Most Audi filter boxes are extremely difficult to access and as such the tech relys on the computer to tell if the flow through is negligible. I have seen several Audi come through with clogged air filter prescreens and elements that have not been serviced since the factory. Bottom line is poor air flow (even with computerized fuel injection) can cause loss of power and excessive carbon build up as a result of incomplete combustion. Have you seen the spark plugs? They would give you an almost instant indication of the combustion chamber condition. As for photos, I don't know why dealer would need photos, other than to cover their backside for warranty reimbursement from Audi North America, who I am sure would have a hard time believing a 15k miles auto could be carboned up. Any respect it will most likely involve extensive overhaul to ensure that the carbon is ALL CLEANED OUT.
  • I have a 98 Audi a4 quattro v6 no turbo. I had a misfire and it triggered the check engine (mil) light. How can I reset it without going to the dealer? Also, how do I reset the service warning indicator?

  • rowlandjrowlandj Posts: 254
    If you fixed the source of the mis-fire then the light will reset itself after a few run cycles. Typically around 3 trips.

    On the other one sorry can't help with that.
  • I drive a toyota camry and mazda cx-7 and they both take all of 3 minutes to change out the air filter. How's that for so-called German engineering?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    That's good but what really matters is how well it filters, not how easy it is to remove, right? :P

    I'm just teasing you--I had a Brand X car that had 7 nuts to remove to get the air filter out, and three of those nuts were different sizes!!

    I have a 2008 A4 / 3.2 Quattro with the exact same symptom, and the "check engine" came on while driving the car home from a 7500mi routine maintenance at a Bay Area dealership (Rector Auto). This was back in late July, and the car has been in and out of two dealerships since then. In fact, just took it back in yesterday to fix oil leaks resulting from the last dealership's repairs (they changed the cylinder heads, injectors, valve lifters, etc.). I still have the sluggish performance, and Audi USA "Customer Advocacy" has been playing hard ball and not willing to replace this car nor reimburse me for the lease payments. Please note my thread on another forum. There are several other folks who have experienced the same issue on their 2008 A4 or A6 with the 3.2l engine.

    I have an arbitration thru Better Business Bureau with Audi. It'd be good if we all could build a case and try to get our cars replaced.
  • Well, the dealer was told to replace the fuel injectors and clean out the carbon buildup. They didn't consider the carbon buildup to be much but did as Audi USA suggested. We've now had the car back three weeks and have put about 500 miles on it (city miles). The car now starts and runs fine. But I'll report back if anything changes.
  • I put regular gas on it for 9months. Which i didn't think it would do harm but what do you think?
  • I have an issue that came up with my 02 Audi A4 1.8T
    Similar to another poster here on this forum. I started having problems with my window on my driver's side not going all the way up.
    Then the other day my door ajar indicator came on for no reason along with the dome lights and audible warning signal. The audible sound would last for a couple minutes and then go off but this door ajar problem seems to happen when I apply the brake, or sometimes turn on or off the radio or heater.
    Also I can not lock my drivers side door by remote
    Now until I get some money together I can get away with having the dome light out and using the key to lock my door but the audible warning is just too much. Also now when I put the head light on the audible won't just beep but it will stay on at a steady
    sound until it shuts its self off and then maybe come back on later. Right now for the time being I need to disengage the audible system but I cannot find the fuse
    that may be connected to it. Nor do I know if there is a fuse for this. Since I could not find it on the fuse arrangement diagram in the owner's manual. If any one might know of this feel free to give a reply

    Your car's engine management system should compensate for the lower octane. All you'd notice was a drop in performance.

    I have a 2006, Audi 4 2.0. My prior car was an A4, 2003, 3.0 and that car had a continual problem with the heating and electrical system. The heating vents would randomly blow cold and/or hot air ... one vent blowing hot air while the other blew cold air. Sometimes they would both blow cold, sometimes one would be warm and the other hot, with distinct temperature differences to the touch, and all the while the temperatures would be set the same on both sides. This problem would occur at random times. This went on for months without any repair success.

    Now, my 2006 Audi is doing the same thing after two weeks of driving. I am dreading the thought of going through the same thing again.

    When I took the 2003 to the dealer, I was always told it tested fine. After 5 repair attempts and being told "it was fine" I drove 28 miles to the dealer when it began blowing cold air so that they could see the problem first hand. They seemed surprised and still were unable to fix it. While this was going on, my brake light fuse kept blowing out and I had to have the light (fuse) replaced 4 times. I thought maybe the problems were related and were electrical? Someone familiar with Audi mechanicals said the problem sounded like the jay flap could be sticking and that he's heard a lot about this problem with Audis???? What is a jay flap?

    Has anyone had this problem with their car? I just got back from a short trip with the 2006 Audi and I got a message that the brake light is out. HELP!!!!!!!!!!!!!!!!!!!! I am reliving Audi hell.

    My 2007 A4 has been burning / consuming oil since it was new. The oil light has gone on 4 times. The PVC Valve has been repaired twice. I am now going through a second oil consumption study.

    Is anyone aware of a consumer that has been successful using state lemon law rules to get out from owning an A4 with this quality problem. I am shocked that Audi and my dealership (in MN) is not standing behind this vehicle and making it right or replacing it.

    Disappointed in Audi.
  • My 2005+ Audi A4 doesn't burn oil, but I was wondering if one can just use any major brand of synthetic oil that's advertised as for European cars. I had not known that some types were for European cars, but I noticed this wording on a few brands at the local Pep Boys. I know that Audi says the oil needs to meet a particular VW spec., but didn't see this mentioned on any oil stocked there.
  • rowlandjrowlandj Posts: 254
    Oils should meet a VW spec in the 504 or something like that range. It has changed over the years but if you look at a label on Mobil 1 0W-40 you'll see it. That oil is the most generally available that does meet the spec and I have been using it for years in my 2004 A4 1.8T. WalMart usually has it but AutoZone, Pep Boys etc... also typically stock it.
  • Thanks. With my A4 coming off warranty service soon I figure I'll get my oil changes outside the Audi dealership. The local Goodyear dealer said they don't do the synthetic oil changes, but they will do it for me if I supply them with the synthetic oil.
  • rowlandjrowlandj Posts: 254
    If your going that route be sure to either provide the large oil filter specified for that car or ensure they use the right one. There are smaller filters that will fit but that engine needs the large filter for capacity and cooling. Without the proper oil filter and the synthetic oil it a pretty sure bet that sludge will form in your engine.
