Hi folks. New to this so please bare with me thanks.
I recently bought my Audi a4 b7 sline 2007. 2.0lt tdi.
Only over the past few days Its started to give me bother. I'll try and explain in the best detail I can.
Normally when I put the keys in and turn to get reds it's would normally bring up the coil light and I would hear the pump prime and then coil light would go out and I could start the car.
But the odd time now I turn the keys to get the Reds and no coil light comes on nor do I hear the pump prime. Also the esp and abs lights stay lit. The car will crank fine but won't start. It does this now and again and I take the keys out of the ignition and then put them back in and try the same steps but still no coil light or prime sound. I'd try the same steps of removing the keys and inserting them again and after about five or six time of doing this I might be lucky and the coil light would come on and then drop out as it should and the pump prime noise is heard and I can start the car fine and drive away at it without any problems. I can then stop the car and start it again with no problems what so ever and I can do this for a few days and still have no problems. Then out of the blue when I go to start the car the same problem occurs- no coil light or prime noise, esp and abs light stay light. When plugged into the vag diagisnostics it's brings up engine control module intermittent/open circuit.
Can any one help.
Many thanks.
