Question about 1998 Audi A4
My Audi A4 battery went dead on me due to leaving my lights on and since then when i start it up it imidiatly stalls. once its up and running its ok until i come to a halt/Stationary the revs go very low and behave irractically.... and the car nearly stalls.. Can anyone help me?
You need to reset the throttle body. Sometimes you can do this by going out to your car and turning the key to the "on" position. Don't crank the engine - just turn it to on. Let it sit like this for 15 min. Your throttle body shoulld reset. Good luck. Check out audiforums. c o m or audiworld for audi spec issues. Good luck!

If your volt gauge reads low, then the low voltage will send erratic signals to your computer and make it run funny.
Could also be bad gas. Try running premium.
Could also be a mass air flow sensor. But it should throw a check engine light in that case.
Could also be a vacuum leak. Raise hood and listen for suction noises.
My Audi charges at about 14 volts b/c it has heated seats, etc,etc. So start with checking your voltage first.

What does the fan do when you restsrt/charge the battery? Start up again? Replace the sending unit, or unplug the sending unit first. If fan keeps running, the relay is faulty.
if it stops, the sending unit is at faulat. good luck

I had the exact problem with my A4 2001 1,9 TDI but i just turned the car on, then first turned the steering wheel to the left as far as it goes, then to the right (i dont know if this is necessary but this is what i did). After i drove for few meters,the light went off and it worked normally.

it's a coil- these are commonly going out on audi's...it happend to me. it's like you are running on 2 cylinders instead of 4- you need to get it replaced- it's about 75 bucks.
