Audi starting A4 Audi. Hit a curb, had a flat. Went to work. Hours later: Drove on flat 200 feet. Inflated with "fix of flat". Start car with lights on low beam. Drove 100 feet. Lights does not go to high beams as needed !! Stopped, turned car off. Turned lights off then attemps to start car. Hours later... After 3 separate 20 minute charges later and a push to autozone. No start, Help needed.

think its a computer system issue-its all connectd these days-even with the steering--disconnect batt then put it back after a minute-may clear up--------if not pull plug at computer clean it and replug a few times-----these reboots at times work------but u mite need to run a thuro diagnostic to see different voltages-go to a good mechanic not a dealer--a hand held scanner will not do this

Mixed up wiring. Check wiring from light fittings backwards.

Check the trans gear oil!!!
Also the cables from the shifter to the trans actuate levers on the trans that sometimes stick. Check the levers.

simply test the battey with a multi-meter and you'll see,, but hope to god that its not a electrical problem its very expensive to fix

Hi i have 02 audi a4 slimline. on motorway going 70 mph and to past a car dropped it down to fourth gear probly hit 90mph. Drove for a further hour and a half, and hear a bang under car. car started to loose power. was drivable but hissing noise come out of it when accelerating. Feels like turbo not kicking in. Would this be that the turbo has blown of maybe burst pipe or something. If anyone can share a light on this i would be very greatful. Cheers

You will need to put the car on a scanner to reset.

weak battery due to shot altenator

make sure you have the correct battery for you car.

Have AUDI reinitialize back up sensors via factory scan tool.

I would suggest you check oil levels etc. Generally these cars suffer from the air mass meter / air sensor problems aswell as coil problems too. Did you ever get a solution to the problem?
