I drove it to the store tonight. When I got home I turned it off. 5-10 min later I tried to start it and it turned over but wouldn't start. I checked for fuel by cracking the bolt at the end of the fuel rail and got sprayed so I'm assuming it's getting fuel. Since I just drove it ( the engine was still warm) and all the lights, fans and radio work, I'm pretty sure it has power. I repeatedly turned it over until the battery died. Then I got a friend to boost it. Still wouldn't start. I checked the fuses but there isnt one labled ecu or ignition and the ones under the hood are in german which i cant read. I searched the forms and google for answers but the only things I found are fuel, spark and ecu but since I just drove it, I don't understand what it could be. Could my ecu just stop working like that? Could it be something easy that I just over looked. Please tell me that it's an easy fix as I don't have a lot of money to put into the car. Thanks for your time.

 

I have a C4 S4 but I'm not sure what's up with your car. Try motorgeek.com as well for more specialised information.

Codes would help, but again 2nd motorgeek as the best source fro troubleshooting

 

At mechanics. It was camshaft sensor. Thanks everyone.
