What can cause my check engine light to come on?
I put a new power steering rack in and have bled the system but continue to have air trapped. It seems to be getting worse any suggestions?
When I start my audi it starts at 1400 RPMs and after a minute it goes down to 600 RPMs. But the car is very loud when running. I'm not sure if its the pullies or the barrings? If I go over 3000 RPMs while driving I can barley hear the person next to me talking.
when stepping on the gas at 20- 30 mph it hesitates and i feel a small shake when it changes gears. had the transmisssion fluid checked it was low , had it filled with the proper fluid , and it still seems to do the same thing???
My MIL came on and after taking it to a certified Audi mechanic, I was told that the timing belt should also get replaced, since practically the entire engine needs to be taken out. I had the timing belt last replaced in June 2007 and have since put 21,000 miles on the car. I currently drive less than 5,000 miles per year. Should I still replace the timing belt at the same time as the thermostat or can the old timing belt be put back on?
The speedometer did not work when I bought the audi.I am getting fault code p0501.i know it has to do with a sensor, but what sensor and where is it located in the car.

What brand of power steering fluid does my car use and where can I buy it?
I had a new fule filter put on. About an hour later the trunk button went out. I had the fuses checked and they were fine.
I returned from running errands in the cold, parked and the next morning when I shifted into reverse it moved 3 ft and stopped. It is making a rattling sound when I shift into any gear as if it is not going into gear. It had no problems before this, didn't make any funny noises, shifted fine the day before. Please advise.
why is my oil crunchy?
The gear shift came off and I'm trying to put it back on. Does the white plastic piece have to be up or down when you put the shift handle on?
