Audi A4 Maintenance and Repair



  • Chelle4, thank you so much for the reply. My car has been sitting in the service department for almost 2 weeks now. I am furious. I called them tonight for a status update and they couldn't even find me in the computer.

    Please, I would love to talk with you in more detail. Is there a way I can contact you?
  • I have more of a question than a problem, but my Audi salesman wasn't much help so I thought I'd try here.

    I just leased an '07 A4, 2.0, standard audio system. Prior to getting the '07 I drove an '06 A4 3.2 for a week and when I wanted to change the radio station on the 3.2 I would just roll the steering wheel control and it would go to the next station on my preset list. Now on my car when I roll the control it seeks the next station it can pick up, not the stations I have in the preset - which really makes no sense to me. Are the systems just different, or is there something I can change in the settings?
  • The clutch of my 2006 Audi A4 went out after just about 5000 miles of use. Audi ruled the problem due to abuse and I was forced to pay $1400 to replace it. Has anyone had a similar problem and know how to refute Audi's desicion?
  • Hello there

    Just wondering if someone can give me some advice. My wife has just bought a second hand Audi A4 SE 20V, 1996 model auto. Every time she starts it she needs to put her foot on the accelerator as soon as it fires to keep it going or it conks out. Once it is going it is fine and has never stalled but it is every time she starts it.

    The other question is that it has the little red light on the dash that suggests an immobiliser or alarm but it never flashes. The dealer gave her the key to the car which isn't a remote key (seemed strange).

    Would really appreciate any help or feedback

    Thank everyone for warning me. I'm stying away from WV/Audi. I was going to buy an A4. I thought my KIA dealer was bad, but I'm in heaven compared to people here. At least, my KIA dealer would always admit when a problem was widespread for my model.

    About to buy a 2006 A4, new, but obviously been sitting on the lot for a while - 6 months or so. I'm already worried about the bad reputation of Audis for reliability, and I will probably exhaust the warranty miles within 2-3 years. Could sitting on the lot for that long increase the odds of problems? Also, how is the stock Symphony II (non-bose) sound system?

    I used to work for VW..and I own an A4. It is very common to see a clutch go out at that or even less miles..VW/Audi clutches should be engaged and disengaged VERY QUICK but not too quick! That's the practicing you need to do, and you will get better at it, ask the service manager. Avoid slow traffic man..I swet everytime I hit one..sorry nothing you can do..they see alot and never cover it, it is considered abuse. I'll tell you though $1400 is a Great deal(serious) mine was quoted $2800 from a friend!
  • I recently leased a 2007 A4 2.0 Quattro w/6sp auto. Have about 1,000 mi on the car (it's just about 1 mo old). Today I had the most frightening experience of my driving life -- while on the highway at 60mph, I stepped hard on the accelerator pedal to change lanes and move around a slow-moving car in my lane. The A4 dropped down a few gears immediately and very quickly I was doing about 75mph. I let up my foot off the gas, only to have the car keep accelerating. I thought maybe I hit the cruise by accident, so I tapped the brake and even moved the cruise lever back & forth. By this time, the car was doing 80mph! My foot was completely off the gas.

    I shifted the car immediately into N and pulled off into the left shoulder -- with the engine still racing (probably 7,500 rpm!). The car came to a stop (again, I was in Neutral). My heart was racing. I shut off the car, put the gear selector in park and restarted.

    Everything seemed normal for the rest of the 15 mi left to get home.

    I know the A4 is a drive-by-wire vehicle with no accelerator cable to get stuck. I was wondering if anyone else had this experience with their A4? Did my winter mat somehow get stuck under the pedal and cause this? I was/am totally freaked by it given Audi's past history with sudden accel.

    I called the dealer -- they said they had no TSB's on this and had not had any A4's where someone came in with this problem. Nonetheless, they said to be safe to bring the car in Monday to have them check it out. All I can figure out they'd do is hook it up to their diagnostic machines and see if any code was saved (did the A4 record any problem?) and/or check to make sure all sensors involved with the drive-by-wire check out and are working properly.

    Any Audi technicians that read this board have any ideas?

    I am totally afraid to have anyone else in my family (wife or kids) drive this thing.
  • I have a 98' A4 2.8 Quattro and the speedometer has gone bonkers. It mellows out if your not accelerating but when you take off it's all over the place. could it be just the speed sensor or what?
  • I have an Audi A4 T 120K miles on it. I just got it back from an oil change and the tech person said to take it to an Ausi delearship right away to get the radiator or antifreeze flushed. Apparently I have the wrong type of antifreeze in it and they told me that I needed a specifice AUDI antifreeze. I have been using this type of antifreeze for a long time and have had no problems. Is it really necc. to replace the antifreeze?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,564
    RE: Antifreeze.

    Yes! You need a RED antifreeze. The dealer has it or sometimes you can find it at parts brand is called "PENTOSIN", and it is supposed to be nitrite-amine and phosphate fee.

    RE: Speedometers. A4 speed sensors are a known frequent failure item.

  • I thought that was just for Audi's that are from 2000 on. Mine is a 1997 and I keep getting mixed signals from different dealers. I haven't had any major problems as of yet. Can I buy this PENTOSIN at any Car Store Like Pep Boys?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,564
    I don't know about Pep Boys. My Audi connection puts it in all the A4s but gee if you've had no problems, there's probably no rush for this. The rule of thumb for Audis is "if it's green, it's probably the wrong stuff" but you know...not necessarily.

    This looks like a good source but I haven't dealt with them personally. They'll sell you all the correct fluids for your make/model.

  • 2tearsnabucket,

    i believe i am experiencing the same problem you describe. i recently took in my 2002 a4 1.8 cvt in for a 80k maintenance. after the first day where the outside mechanic did the maintenance and flushed my coolant system, he ended up fixing a leak in the coolant system and replacing a purge valve. now i feel a tremor at low speeds. although he seems to have done a good job in the past, he does not have a lot of experience on these "new" cvts and suspects it may be the transmission. he recommends bringing it into the more expensive dealer for some kind of computer that he does not own to run a diagnostic. if it is the transmission, he recommends complaining to audi to fix it although it isn't under warranty. what do you think? reply to me at if you don't mind. thanks

    Actually, it would be a lot better if people would respond to you here rather than take the conversation off-line. That way lots of folks can benefit. ;)

    If you have just accelerated hard and then let off the gas, it may be shifting up a couple gears suddenly to save gas.
    See the following post on the Texas Audi Club forum:
  • I am in the process of preparing to install a GENTEX auto-dimming mirror in our 2003 A4 Quattro and I'm at my wit's end trying to figure out a way to remove the original mirror without breaking the windshield. I contacted our local dealership to see if they would remove the OEM mirror, but they didn't want to have anything to do with it, although they did say that if I wanted to take a chance, just twist the mirrot counterclockwise until it is vertical and then wiggle back and forth!! At this point I'm considering using my Dremel Moto-Tool and just slowly cutting it apart in little pieces!! Anyone have any suggestions?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,564
    here's a suggestion from another forum but I'm not endorsing it, just offering it up:

  • I leased an Audi A4 2.0T 2007. Three days 160 miles later, the car stalled on the freeway. The dealer towed the new car back to the dealer and gave me a loaner. Today I found out that one of the hydrolics components in the transmission was defective and it was being replaced. They also said that they wanted to test the car for at least 30 miles, to make sure everything was OK.
    My question: Can I legally request the dealer for a new car and refuse the car being repaired?
  • Have you received any feedback from the Audi dealer? I had a problem with my new Audi A4 I was on the freeway doing 70 75 mph I noticed my speed was decreasing even though I was accelerating, I got to a point in which the car just woudn't go and moved to the shoulder. As soon as I stoped, I noticed the gear indicator in the instrument panel was flashing. The engine was still going and the car was ingear but going no where. I switched gears back and forth with no luck. I turned the engine off for a few minutes. Once I re-started the car it worked fine. I called the dealer and they towed the car. Today I found out that the transmission has a faulty component that they are replacing.
  • I have a simple question for any Audi owner out least on the A4 2.0T CVT model for sure. I am looking at purchasing one and when I was test driving it the other day I noticed one of the slots on the transmission shifter was an S below the D. Is this for a sports transmission, or something else entirely?

    If so, what does it do, or better yet, I am assuming it increases the RPM's, but to what?

  • My A4 (1.8 T, shift stick, 2WD) warranty expires in 60 days or 3K miles. I am looking for some practical advice on how to get the car serviced at the dealer's expense to prevent as many post-warranty problems as possible.

    My current plan is to take it to an idependent mechnanic (suggestions in the Northern VA area are welcome) and pay to have a full in-depth inspection. Though, I would like to come to this mechanic with a list of things to check for based on the most common problems experience by other owners in this forum. I would appreciate if you could post a list of the problems that you have experienced as an A4 owner. Any other advice will also be very much appreciated.
  • I had my vehicle completely overhauled by the dealer with just 100 miles prior to my warranty expiring. They were not happy with me and tried to tell me that they certain things were not due yet, however I took in my maintenance book and common sense. They will not tell you, but even things like cosmetic items are replaced at their expense. I had several of the black buttons replaced because they were peeling, I had the console replaced because it began peeling, I had all fluids replaced, etc. There were about 15 things that I had them fix or replace at their cost. I do not know if you have had any engine trouble yet, but at 70,000 miles Audi had to replace the engine in my car because of the oil sludge problems that they are before your warranty runs out have your engine checked out. They are supposed to honor it for 8 years. There is a class action lawsuit about this, so if they don't want to check your engine, remind them about the lawsuit. Anyway, good luck. I love my car, but will not buy another Audi because they do not stand behind their product.
  • I thought this was an interesting survey from Top Gear that may stir some discussion.
  • I live on the east coast and the recent snow seems to have adversely affected my manual transmission. I was driving on a major road that was unplowed and the snow and ice was scraping the under-carriage of my 1999 A4 Quattro 1.8T. Now I'm getting a grinding noise and shaking and shifting into every gear is not as smooth as before. Any help or suggestions as to what is causing the problem is greatly appreciated.

    Hello I live in Ohio and I have a 99 A4 2.8, recently car has been good and does well in the snow. I know it is very stupid of me but car has been below 1/4 tank for a few days now and it has been bitterly cold "constantly below freezing and below zero recently".

    Anyway, I was leaving the other day and my car started just fine but was running very rough, then the chk engine light started blinking so I turned it off. Went out today to start it and it did the same thing, albeit still very cold.
    Now i've heard about freezing gas lines and that is very possible here but I was under the impression that the car would not start at all if that were the case.

    Has anybody had any similar experiences and could this be a cold weather problem or do I have an engine problem. Thanks in advance.
  • YES!!! I had a very similar problem last week. I was pulling out of a parallel parking spot. I went in reverse to give myself room, tapped the gas and when I went to hit the break the car continued to accelerate into the car behind me. After the crash, with my foot slammed on the break I put the car in drive to try and change directions and the car jetted out into the street at full speed. At this point I kept slamming on the break, and the car would not stop. Not knowing what else to do I placed the car in park, the car halted to a stop. I jumped out of the car, afraid the car was going to keep moving since the engine was still racing. My boyfriend (who witnessed the entire thing from the sidewalk) ran over to me, reached into the car and turned of the engine. He carefully restarted it a min later and it was still racing, so we again turned off the car. I called Roadside assistance but was on hold for a long time. After about 10 min he tried the restart the engine again and it was fine. He drove it cautiously around the block with out incident. The car was brought to the dealer that day for "diagnostics." At first they told me that it was probably just the floor mat-this happens “all the time.” But they checked the mat and it was secured in place and I did not have the second mat that they say is usually the culprit. (If this is such a problem why don’t they put a magnet or something to keep it from catching on the accelerator???) After I waited 45 min they told me, they really have not found much BUT that AUDI corporate wanted to send out an engineer to inspect the car. I left with a loaner and am waiting to hear from them.
    This was hands down the scariest experience of my driving life- I could have killed someone. I was interested to know that other people had similar experiences. What ever happened with your car? Has it happened again since? I'm kinda scared that they are going to give me the car back and say that "nothing was wrong." Something was defiantly wrong with the car! There were 5 people watching that will agree that while I was standing outside the car, it sounded as though it was going to take off. Luckily there was no real damage to my car, but sadly I can not say the same for the car I hit. I just feel so lucky that this was not a worse accident. I never want to be in this situation again. What should I do?

    1999 audi a4 quatro 2.8L, am trying to locate the fuel filter. is there anybody knows where can i locate the fuel filter? thanks!
  • I left my headlights on last night, AAA came by and jumped my car - and everything is working fine. However, after starting up the car the gas gauge is at empty - and the electronic reading that tells you how many miles are left on the tank reads "0," everything else electronically is working just fine. I've started it up a number of times since then with the same problem... There should be at least 1/2 tank in it now...
    Any suggestions?

    Were you able to solve this problem? I have an '02 Audi A4 with similar lagging/lurging problems when trying to accelerate. Just wondering if you were able to find what was causing this. Thanks.
