Audi A4 Maintenance and Repair



  • eddie650eddie650 Posts: 26
    I have a 2005 A4 convertible still under warranty and have an occasional front driver window problem. When I try and shut the window, it occasionally does its own thing - going up, then reversing and going down. Eventually, I am able to get it to do what I want. I know if I mention it to the dealer, it will not act up on that day while it's at the dealership. Should I be able to get this system replaced while it's under warranty - if it doesn't act up at the dealer? My warranty coverage will soon be up.

    Thanks for your advice.

    First, where do you live and what was the temperature? I had a similar problem with a 2002 A4. It did it only on days when the temperature (outside) was over 95degrees and the interior temperature was much more. Once the A/C was on and the inside temperature came down the "mind of its own" stopped. I do not know if it is a built-in safety device or just a temperature contributing issue. Hope I could help more but might help to start ruling out things.

    Thanks for your reply. I live in Long Beach, CA and I'm sure the temperature was not an issue here as the temps have been moderate. I will certainly take note of the temp when it happens again. I will be taking the car in for an oil change in a week and will certainly bring up this problem to discuss it when I'm there.

    There is also a process to re-sync the window auto-up and auto-down features. It involves closing with the switch and holding it for a few seconds then open it and also hold the switch again. I believe there is a mention of this in the owners manual somewhere, perhaps in the section for battery replacement.
  • Guys,

    I've got a 2005.5 A4 2.0T with about 44500 miles. At around 33k, I began to notice a slight engine knock when the car was at idle, after it was warmed up and idling at a very low RPM.

    I took the car to the dealership and they had it for nearly 3 weeks, and they had trouble diagnosing the problem. They eventually replaced the camshaft and some other things, but the noise remained - they didn't really fix the problem.

    I've now got around 44000 miles on the car and the warranty expires in about a month, and I'd like to know if this "knocking" or "tapping" is a sign of something detrimental, or if it is no big deal.

    I've since moved and am going to take my car in to another dealership to have it inspected before warranty expires, and probably have them look into the noise. If it isn't a big deal, then I won't fight them too much if they can't fix the problem. However, if could possibly lead to bigger issues down the road, I'd like to contact Audi and find out what my options are before warranty expires.

    The noise is not easy to describe, but you would understand it if you heard it. It noticeable enough that if I start the car in a parking lot and let it idle, I get many glances from strangers. It's kinda like a "tap-tap-tap-tap-tap-tap-tap", at a rate of about 3 taps per second.

    Hello, first time on here. My question is I have a flat tire and I know I'm not incompitent, but I can't get the tire off. Did as the manual said, but she won't come off. That main bolt in the middle of the tire, does that one need to be removed as well and if so how do I remove it.
    Thank You'

    Mine does too. Has 3000kms and was a dealer demo. It's got Michelin tyres which are also very noisy. I had the tyres changed front to back, wheel alignment and 4 wheel balance and I still get enough vibration to annoy me at between 100 and 120 kph. The only thing I can think of to do is to change the tyres to something else like Pirelli P7 which I know are better. These are virtually new so I will wait a while. Have you had any further info?
    Please let us know. thanks

    Thanks for your tip and I'll be sure to try that the next time it happens.

    Hello, I drove off from on top of a curb (on purpose) the other day, and once my front wheels got off the curb, I scraped the bottom of the car on the curb. It seems as if I cracked the plastic covering that covers the bottom of the car. Nothing is leaking so I don't think I did any major damage. Is that plastic piece protecting anything important that can't be exposed to rain, or any other debris from the road? Should I get it fixed?


    Btw, it's a 2005.5 A4 2.0T
  • rowlandjrowlandj Posts: 254
    It would be wise to get that shield fixed. It serves a purpose and improves air-flow in the engine bay aiding in keeping the engine cooler. Also, it does keep debris and road-spray to a minimum in the engine bay.
  • really not sure
  • Guys,

    I just got my car back today from the dealership - this is in regards to the "knocking" at engine idle that I've had since I purchased the car at 33k. I've already had it in the shop about a year ago, but they couldn't fix it. I took it to a different dealership and I am happy to announce the "knock" is GONE!

    For anybody curious what the issue was, here is how the invoiced reads:



    I also reported an issue with the starter that made "grinding" noises prior to the engine cranking over, and this issue was also fixed and was directly related to the first issue.

    I'm really pleased!!!
  • Guys,

    Now I need new tires. 2005 A4 2.0T w/TPMS Quattro. Tire size 235/45/17.

    Audi Dealership that fixed my knock problem has Cooper Zeons at $780 which is everything including allignment. I'm currently kinda residing in the sticks, so I can't do Discount Tire or anything like that. We have snow 6 months outta the year, also.

    My first concern is how good of a tire this is in terms of wear? Second, what is a better all around tire for the price? My most important conern is bang for the buck, so if a tire is a bit noiser or has less traction, that's ok.

    I have no experience with A4 tires, so any info is good info.

    I would ask first is your car AWD
    If you can ask the original owner and if it snows where you are for 6 months a year and you said the car you have owned for over a year, how did the tires on the car now hold up in the snow.
  • Well, this past winter I ran a separate set of wheels and snow tires, but I sold the set a month ago. They were Audi wheels, but they were only 16's and didn't look as nice as the original wheels. BTW, car is QUATTRO - AWD.

    I've got Pirelli's on now, but I think they're a bit pricey. I was just curious if anybody out here recommends a specific tire ranked in the following order:
    -tread life (not advertised, but actual)
    -road noise

    Also, what's an average price to pay for new tires and everything that goes along with new tires including alignment? Is $780 reasonable and are Cooper Zeon's ok???

    I Have the same problem with the engine "grinding" noise when I first start my
    car. I have a 2005.5 a4 2.0t quattro and complained to the dealership a couple
    times and they say they can't fix it. I eventually called audi of america and
    told them about the problem and also to ask them if they knew anything about it.
    They said it was due to the engine oil not heating quickly enough or something
    but doesn't do any damage to the engine. They also said there is no repair for

    So what you had done actually corrected the problem? Which dealership did you go
  • Sam,

    Yes, whatever I explained in my post above in regards to fixing the "knocking" sound in the engine, definitely also addressed the sporadic "grinding" sound of the starter. I should mention that the sound of the starter was something like you would hear if you've ever accidentally kept cranking the starter once the engine turned over - it's a difficult sound to describe, but I knew it was an issue because I could reproduce it at will - not a big deal, but my initial worry was the starter going bad and my warranty is due to expire, so wanted it addressed.

    Again, I'm not sure if we're talking about the same thing here, but if you look in my post outlining the fixes, you can maybe mention this to your guys. Do you have any issues with a slightly noiser engine at idle? I didn't really notice it until my brother mentioned it to me saying that didn't sound right - it almost sounded like a diesel with a continual rat, tat, tat at idle.

    Since my car is also a 2005.5, our issues might be related. I'm really particular about my cars - especially expensive cars, so I wouldn't doubt if a lot of people have this problem but don't really care about it.

    The dealership that finally addressed my issue is Kocourek Audi in Wausau, Wisconsin.
  • Yesterday I was driving home and my acceleration just died on my on the highway. I tried to start it back up up and i noticed the engine wouldn't turn over. I was told that it could be a timing belt problem or a trasmission problem. I am praying that it is not the latter. i need any help with this issue. my car only has 87k in mileage. any suggestions would be greatly appreciated.

    I think it's the same exact problem. It doesn't do It all the time, but I would say 8 times out of 10 it happens.

    I have found a temporary solution to our problem. If you turn the key to the 3rd stage before actually turning the car on (so all of the electronics are on and the lights on the dash) and wait a few seconds before starting it, it will eliminate the problem probably 50% of the time. However this still doesn't completely fix the problem. I will bring my car in again and tell them to do whatever it is that they did to your car to fix it.

    Luckily, I had the dealer look at the problem before my warranty ended (which was at the end of march) so I should still be covered

    Thanks for all your help and also, have you had any other problems with your car?

  • does anyone know how hard it is to replace a radiator / thermostat? dealership quoted me over $5k!
