#840 of 2367 A4 Warm Engine Starting by ernestob7

Jul 18, 2005 (11:33 am)

My 2001 Audi A4 Quattro with a 2.8 engine has a starting problem when it has been driven and then has been allowed to set for about 2 hours. I'm barely able to get it started after cranking it until the battery is almost dead. Sometimes I have to wait several hours to allow the engine to cool. This does not happen all the time but often enough to be troublesome. The engine always starts just fine when the engine is cold. The dealer checked the starting system, inspected the intake for carbon buildup, and checked if it held fuel pressure after the engine was turned off. They said everything was within specs. To their credit they did not charge me anything since they found nothing wrong. Has anyone had this problem and if so what was the solution?

My check engine light is on in my A4 2001 -1.8T. The diagnostics have said it was the catalytic converter- so it was replaced, then the oxygen sensors, which I replaced. It came right back on - now it says fuel too lean - came on at 45MPH - this is what the mechanic said the diagnostic tool said - Any suggestions on what to do to get it to stay off? I would like to sell it - it runs fine - but no one would want it with the light on!! I guess it didn't get enough gas when I accelerated at 45MPH - it kind of quit - I had to slow down and eventually gain speed. Thanks for any advice!

When I try to turn on my high beams they don't come on unless I put on the left blinker. Also, gas gauge is whacky and now my speedometer isn't working - are these problems connected? any help would be greatly appreciated!

Disconnect the battery, then reconnect. Sometimes "rebooting" will solve some of the "gremlins" you have described. Be sure you know your radio "safe code" before doing this, the radio will lock up after reconnecting and the code needs to be entered to turn it back on.

I had the same problem. Replace the coolant temperature sensor. I had a mechanic do it.

#845 of 2367 Multiple Problems with my 97 A4 by pitoune

Jul 19, 2005 (6:11 pm)

I have a 97 A4 at 91K bought used from an Audi dealership. Since I have owned the car I have had to replace the rear brakes twice, front brakes, rotors and just had the catalitic converter replaced. My check engine light is still on. I was told that the catalitic converter was the cause of the light coming on and that it needed to be reset. I unplugged my battery, waited aprox. 3 minutes then hooked the battery back up. The light went out but 2 days later is back on. Also the trip meter blinks and says "IN 1" for about 3 to 5 minutes and then will show the correct mileage. Half the lights on my dash do not light up either on my spedometer and tach. Has anyone else had similar problems or have any idea what the actual problem could be? Any suggestions greatly appreciated.
