I have a 1998 Audi A6 Quattro and have been having problems but can't figure it out! My car died out a few months ago and I assumed it was either the Alternator and/or battery since I have a sound system installed. *The sound system has been in for close to a year before this problem started. However, my battery is still new fairly new, just not sure if it has taken a beating from my sound system... A friend of mine told me that when I jump start my car I could test my alternator by taking off the positive and negative wires from the battery. If it dies out it is the battery, if it stays running it is not the battery. When I did that, the car stayed running so I assume it is not the alternator. Not too sure if that is 100% guaranteed though.

So I jump started the car and it started right up. I drove it around for a few hours. Came home, turned off the car, waited for about 6 hours. When I went to start the car last night (after sitting for 6 hours) it started right up again, my girlfriend drove it for about an hour or so with no problems. The next morning (today) we went to start the car and it started just fine. My girlfriend was driving to work and when she went to check the mail, she turned off the car. When she came back to start the car it didn't start! So she had her dad come down and jump start the car. It started with no problems, then they drove it to his house to park it. Waiting for a diagnosis...

Any input / suggestions would be helpful.

Battery? Alternator? Or a short in the electrical somewhere?

Hello just recently my A6 from take off felt sluggish when first driving off. It fills as if I had the parking brake on when starting to drive off. Then as I build up speed it fills normal.

My check engine light, abs,and air bag light is on. I recently had o2 sensors replaced and now the car is running very poorly. There is little acceleration, misfires, and just a terrible sounding engine. i took it to a foreign car specialist who said that the computer is shorted out and needs to be replaced. I need to find out where it is located so that I can get the part number to try to find a used or remanufactured one myself. where is the computer on a 2001 a6 quattro wagon?

The car stopped running a few months ago and had an authorized mechanic look at it and states it needs a new transmission. What should we do and about how much does it cost to relace the transmission?

Hi,

I will have added approximately 1 1/2 qts of oil since my last oil change 5k miles ago. I change the oil every 5k miles. It's not burning it as far as I know becuz I passed CT emmissions with no problems.

No leaks that I can see also.

Is this usage normal for this engine?

Thanks for your help.
