Audi A4 Maintenance and Repair



  • Hi
    I have the same heating problem. I wanted to know if you found the problem and if it fixed your heat. I am about to replace the timing belt and water pump but can not belive this will fix my heat. If you could or if you know where I could get more information on this please let me know.
    thank you, pierre
  • Could you give me some information as to whether you were able to make any warranty or extended warranty claims. My oil pump was replaced on my A4 due to sludge. The two weeks later the fuel pump died (on highway while travelling over 60mph) very dangerous. Audi is saying that the fuel pump problem is not related to the sludge problem. Do you have any inf on this? Thanks
  • I am having a similar problem. Please tell me about yours.
    At 55,000 the car died while running. They said it was the "oil pump" and replaced it under the sludge extended warranty. They had it for three weeks. Two weeks after it came out of the shop it died again on the highway..This time they say is is the "fule pump" and that it is not related to the oil pump. would love to know your problems

    I have a 1997 A4 with an Auto trans and am having issues also, only I loose overdrive and reverse. After re setting the computer everything goes back to norm. If you find anything out please email me.
  • I own a Honda accord 93 4cyl for 12yrs now. I never heard of such incredible mechanical problems A4 owners experience. I want to ask you if you guys have dump the A4 yet? Is it worth keeping it at all? I am planning to buy accord 2006 V6 EX model. I test drive it on the hwy. It drives very smoothly and accelerate with ease into passing lane. I had no problem keeping up with expensive European cars.

    Well, the fact that this is the "Audi A4 Owners: Problems & Solutions" forum, then pretty much all you're going to read here are problems that people have with their cars....
  • I just made a deposit on a manual pre-owed 2005 A4 2.0T (the newer model, the FSI one). The car only has 82 miles. My friend test drove the car for me and he said the car was smooth. After we got back to the dealer and popped the hood, the engine sounded kind of loud. It has some kind of “ metal knocking metal” sound. We asked the dealer and he said it is normal. Then he offered to pop another one (new 2.0T Quattro). It sounded loud too but did’t have that shape metal knocking sound. So is it normal? The car is new. We asked the dealer how the car was used. (They said the car was Corporate Demo) But he isn’t sure the history of the car neither. He said it might be used in the car show, picture models, stuff like that. I worried perhaps the engine was screwed by the ppl who test drove it. Thus, my main concern is the weird sound from the engine. Any clue? Thx

    yesterday was the first really cold day here, and my car was outside. When I started it up there was no sound at all from the radio... the display and tuner worked fine, in fact it was reading the satellite channels and songs, but no sound. AFter 15 minutes when the car really warmed up the sound came back on. I have the upgraded bose system in a 2005 A4 Cab. I am not happy about this.. I wonder how many other people are having this problem. Any posts with regard to this problem or what the outcome was would be appreciated! My daughter has a 2003 A4 and I have driven it in below 0 weather and never a problem with the radio!!
  • You are correct in a way. You are saying that if you put up a forum with the title 'problems' then all you are going to read about is problems. So, one might conclude that there is nothing good about the car. People tend to complain when things are going wrong but, do not take the time to complement if things are good.

    However, look at the specific problems you are reading about on this forum and how Audi service centres and the manufacturer deal with them. You are reading about similar problems by different car owners all over north america. You are reading about how the Audi service centres do not know how to solve the problems. You are reading about how problems crop up over and over again. This is what is significant in this forum.

    Furthermore, I bet you can see that there are forums for problem reporting for other cars too. But, the A4 seems to have the highest number. This probable because the A4 is poorly wired or poorly manufactured. Also, service centre mechanics don't know how to fix a problem because their "computer" does not show any problem even though the owner can tell you exactly what it is. The A4 and Audi and its service centres do not back up their product and the owner suffers.

    By the way, think about all of the other owners out there who are just sucking it up and going along driving a poorly performing care with many manufacturing defects!
  • By the way, even if there was just one problem, dont you think that the manufacturer or the dealer service centre should resolve it? One way or another way. It just sounds like a lot of people are just unsatisfied
  • About 8 months ago I bought a 1998 a4 audi quattro 1.8T. Great car, but I'm having some many problems with my two front windows. First my passenger regulator went. Then my right window dropped and never came back up. So far, I replaced the passenger regulator, but it still struggles on the way up. The driver window needed a new master switch, which didn't help the situation, because after I put the switch in, I realized I needed a new motor. The be sure, I bought two from a salvage yard. Both motors worked, but they still struggle to push up the windows, even with a new regulator on the passenger side, and the new master switch on the driver side. I'm running out of options, and don't know where to turn next. If anyone has any advice, or has heard of a similiar situation that could provide some helpful info, please let me know! Thanks
  • 82 miles sounds catchy. But, Make sure you ask to look at the previous work order history on the car. Actually get the service centre or the salesperson to show you on the computer the entire work order history of the car and make sure that you know what you are looking at and ask questions about the things that you do not. I wish I had with my 2002 Audi A4 which the dealer told me had some things fixed in the shop but they were not really a problem. Well I regret accepting his word for it. Because the cars previous problems have plaqued me for the past two years. I am in the shop every two months with the same problems repeating and new problems cropping up. Do not take a salespersons word for it. SInce you are about to pay big bucks for the car . You should have proof of where the car was. He must be sure of the history of the car. People who use cars for demo's etc. WRECK them. Dont take his word for it..protect your money.

    Purchased my frist audi about two weeks ago and love the way the car handles and drives. However the engine does not idle smoothly. Have the 6 speed auto trans. Does enyone know if this is a common characteristic of the car?
  • I purchased a 2002 a4 quattro (52,000 miles) about 2 months ago from CARMAX. I got the extended warranty. Love the car but just had my first problem last week. Driving to work the engine would not go over 4000 rpm. After I shut the engine off and started it back up the check engine light went on. Still would not go over 4000 rpm. Seems to run fine though. Took it to car max. They said it was some speed sensor. They replaced it and I picked the car up. Worked fine for 2 days.. now I have the same problem. I know the check engine could be just about anything.. just looking for input from other owners.
    ALs.. sometimes I have to crank it over 2-3 time in order for it to start.
  • Unfortunately I have not been able to drive my car since 12/6 because I had a minor accident so I have not been able to test the radio again in cold weather. I too have the upgraded Bose system so I am wondering if this a problem w/ that particular radio. The UP Dallas dealership told me another person came in with the same radio problem, however he could not even tune his radio or see the display. After 10 minutes in the car his radio came on. If this problem happens again I will definitely take my car in to Audi to have the radio thoroughly checked out. I agree with you that this should not be happening at all.

Power and Associates Initial Quality Study of owner-reported problems in the first 90 days of ownership, Audi ranked No. 8, an improvement of three spots over 2004, but still far behind Lexus, the No. 1 quality brand.

    More troubling, in Power's Vehicle Dependability Study -- which measures owner-reported problems in three-year-old vehicles -- Audi ranks near the bottom of the pack. In fact, at 312 problems per 100 vehicles, Audi ranks just ahead of Daewoo, a true budget brand."

    Quote:"The A4 has generally been a reliable car, with electrical problems being the most common shortcomings according to Consumer Reports. Faulty ignition coil packs and window regulators are two of the main culprits in that regard. BMW's 3 Series offers slightly better overall reliability according to Consumer Reports, but the Acura TL and Lexus IS300 take top reliability honours in this quartet of cars. "
  • I have a 2002 A4. The rear brakes are dragging intermittently.

    It was serviced for this problem with a brake rebuild about eightmonths ago and is recurring.

    The rear discs were glowing red yesterday, and I am about to call the dealer.

    Has anyone else had this problem?
  • My dealer has a certified '05 A4 3.0 6 cyl. w/ 8K miles. It was one of the shop loaners.

    Since it's certified, it comes with 6yrs/100k warranty along with 4yrs/50k free maintenance. Between the two, shouldn't that cover most of the problems on this forum? I'd hate to have excessive repair costs + a simultaneous car payment (am going for 60 mos. loan).

    I appreciate any help. I didn't want to make an impulse purchase - the car is gorgeous, but I worry about reliability and repair costs. I just thought I'd post here to see if I could get any feedback. This is a really terrific research site.

    Thanks all :)

    I wouldn't get a loan for longer than the maintenance warranty and I wouldn't plan on keeping the car after that ran out. It will cost you an arm and a leg to keep it running after that.

    Good luck.

    2001 A4 1.8T manual
  • Hi all,
    I have an Audi A4, 1.8T, 2002. As soon as my 4 year warranty expired suprise suprise, problems began.
    The check engine light came on. After a visit to Autozone, I finally found out that the following error code was causing the problem:
    "P0171: system runs too lean". Anybody has any idea what the problem might be? I was told that it might be a senson malfunction and that i might have to replace it (i was told it costs around $180). Anybody experienced similar problem? The car has been running without any noticable change in behavior with "check engine light" on for 4 weeks now. Do you think that I might cause more damage if I don't have it fixed?
    Thanks in advance for your input.
  • The Diagnostic Trouble Code (DTC) you mention could be from a faulty or contaminated exhaust oxygen sensor. At best you're burning too much gas, at worst you've got a deeper mechanical problem.

    Check out for more info.
  • just bought 2002 Audi 1.8T quattro, 3rd day driving the car
    I keep hearing loud noise coming form the back side of the car , it gets louder when i get closer to where the fuel tank is, some one told me it could be the fuel pump inside the tank need to be replaced does any one experience some thing like that could it be really the fuel pump or some thing else,
  • I have a 2003 Audi A4 1.8, 54000 miles. Tonight, my clutch went on the car. Have any of you had any successful experience dealing with Audi of America regarding covering this problem with only 4,000 miles beyond warranty? Any help or suggestions would be appreciated. I guess the posts on this board are correct...decent car until the warranty runs out!
  • what exactly does the noise sound like? I had noise from the back too with the same car. It was a buzzing sound that was very loud, kind of like a piece of mettle rattling very fast and loud and the sound got louder when I accelerated. It turned out to be the muffler needed re-welding.
  • Audi is not reliable. You may get a warranty but the car can be in the shop every few weeks diagnosing and servicing problems. Do you really want that???? Don't buy it despite the hype about all the warranty.
  • I did do that but I have only 8 done at Audi and I need like 9 or 10. They won't pay for anthing because of that.
    They should of recalled the cars to replace the engines but they are just trying to hold us to a stringent test so they can save money. Piece of junk engine.
  • My problem is the oil light came on one cold morning and ultimately i had to stop driving it. I had it towed to the dealership and they are telling me it is an oil sludge problem. I don't have all my oil change receipts(8 out of 10) They are telling me I possible need a new engine. They want $650 to just to tell me that and that Audi won't cover it. Crooks if you ask me. They should of recalled these engines. Instead, they make you jump thru hoops on a problem they know they have.
  • I had the same happen to me as well. The problem was with the catalytic converter that reduces emmissions. It is mandatory that the car meets emmission standards set by the EPA and Audi has a mandate to fix the problem for free. My catalytic converter was replaced after the warantee was over for free at my dealership and I did not have the problem any more. So you might want to mention this to them.
  • Hi,
    I got my 2006 A4 Avant (quatro, automatic) this summer and about a month after driving it I noticed some 'kicking' behaviour whenever I come to a stop - the car simply 'kicks' right before stopping. This behaviour happened occasionally so duplicating it at the dealership service shop was a bit difficult. Consequently, the dealership did not find anything wrong with the car (total number of visits regarding this problem = 4). Finally, the dealership general manager said that this behaviour is normal and that it is the breaking system with its security features (note: service manager was not aware of this feature).
    The thing is that none of the cars that I had driven in the past behaved like that, even my friends Camry drives and stops as smooth and quiet as possible. Currently, my Audi 'kicks' everytime I come to a stop and this is extremely annoying.

    Has anybody experienced a smilar problem? Can you please advise?
