+++Possible Engine or Electrical Problem+++ by tcelik

Car Specs:
1999 AUDI A4 QUATTRO
~135,000 Miles
 
Lately the car has been giving a few problems. A couple days ago white smoke came out of the exhaust for a while (5-10 minutes). The car itself drains a lot of oil and leaks a little, I brought it to a mechanic and he said it might be the head gasket or just simple the car may be burning oil. Yesterday I left a light on in the car by accident and the battery died. I charged it today and the car gave a engine check light. When I tried driving it, the car would go up a few rpm and would suddenly drop no matter how hard I held down the pedal, meaning it wouldn't get above 5-10mph. It would just rise and let go, rise and let go...
 
What could be the problem? Maybe an electrical malfunction, maybe the battery needs replacing? Or maybe something wrong with a cylinder?
 
Please help me as soon as possible, thank you.

Electrical Window Problem by eddie650

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.
Cheers

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.

2005 2.0T Engine Knock ... by hauschild1

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.

Audi A4 flat tire by bundyt

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'

Hi
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

Cracked Undercarriage by samaudi

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?
 
Thanks!
 
Btw, it's a 2005.5 A4 2.0T
