#1373 of 2367 Intermittent "clicking" sound when braking
Aug 21, 2006 (6:25 am)
The brake pads and rotors needed to be changed on my front brakes for my 2001 Audi A4 recently. The car has 92,000+ miles on it. Ever since, there has been an intermittent “clicking” sound, when I step on the brakes. The repair shop initially thought that the rotors may have been bad, but nothing changed when they completely re-did the brake system, including replacing the calipers. The shop then had someone come in that specializes in Audi to look at everything. It all looks okay, but they indicated that this has been an issue that seems to come up, when the rotors and pads are replaced at the same time. They indicated that it usually takes around 1,000 miles for the pads to set in, and they noise then goes away. I have driven around 1,500 miles, but the noise is still there intermittently. Any suggestions to fix this problem, or do I have to just be patient until the noise goes away by itself.

#1375 of 2367 '00 A4 1.8T high-mileage maintenance
Aug 23, 2006 (8:55 am)
At 82K miles, I've opted for some major maintenance.
I'm having the timing belt, water pump, pulleys, belts, etc. replaced.
The clutch hasn't been slipping, but it doesn't engage until the pedal is nearly all the way out. To save another trip back to my mechanic, I'm having it replaced at the same time.
My mechanic also found some control arms that need replacement.
To anyone with past experience with these types of repairs: any tips?

All this stuff sounds fairly similar to the issues that have come up on my '99 A4 2.8.
I had the timing belt recently done. I paid $750 at a local shop for everything you mentioned.
The 1996-2001 A4s have high clutch engagements, only the first couple of inches when you press on the clutch does anything. Did the clutch engagement position change on you over time?
Control arms are a common issue too. I'm not surprised you're having them replaced.
And by the way, if your ABS light starts blinking, it is usually the controller module gone bad. You can get a new controller module for $550 ($750 installed), OR, if you're handy, you can remove it and send it to Modulemaster (www.modulemaster.com) and have them fix it for $250.
Oil cover gaskets often leak around now too.

I noticed that my clutch has been that way since at least 50,000k maybe longer. I'm currently at 110,000k and still no slippage. I was told by someone that it is a self adjusting clutch and is supossed to be that way. So I never fixed it and it just seems fine to me...
#1378 of 2367 Audi Sludge help
Aug 24, 2006 (11:03 pm)
I have gotten some relief from Audi regarding my engine problems. I actually have gotten a reporter who is interested in doing a story on the problems with Audi. If you are interested please send me an e-mail and I can pass it on to the reporter. He is doing the story on the engine sludge problem.

Just curious what sort of engine problems you've had. I have a 2002 1.8t a4 and have noticed that there appears to be some sludge on the engine oil cap. I'm bringing it in to have it checked out tomorrow but will remain nervous driving the car knowing that the engines are so prone to these problems.

Audi's extended oil change intervals have been a nightmare for more than a few folks. I've always used synthetic oil and changed it either every 5k miles or every six months, which ever comes first. I'm currently on my third A4 (an '06 with the two liter engine) and so far nary a trace of sludge in any of my Audis... and two of the A4's had modified engines.
So far my current '06, which recently had its one year birthday, has been perfect. And even last winter during the coldest weather, the car didn't have a squeak or rattle.
Audi has indicated that improved quality is a high priority and hopefully my car will prove to be the norm, not the exception.

Hi, I have had my engine replaced by Audi and I am still having problems with the NEW engine. Be careful when you go into Audi, they are going to try to find a way not to replace your enigine. If you have all your records take them with you to show Audi.
