Hello everyone, new to the board. the Audi A4 that I'm having a problem with isn't mine, but a close friends. It randomly died turning a corner today and It started up and ran for a few seconds and then shut off again. We tow'd it to my house and once there it started but ran real rough around 200rpms, trying to run. I can't seem to find where the relays are located at and I'm totally new to the Audi world. I check for codes and it didn't find any. The In2 light is flashing but it's been doing that for over 1500 miles. we unhook'd the battery for 10-15 minutes and then rehook'd it and it started up and ran fine for about 5-6 seconds and then shut off again and couldn't restart. We then check'd to see if there was any spark and we found there to be none... I then check the fuel pressure by unhooking a fuel line and turning the car over and none came out. Is there a EFI relay that may have gone bad for niether the spark or fuel pump not to work properly or at wierd/random times? any help would be greatly appreciated. thanks for the time.

you sound like you know a little something about cars so ill ask this, did you listen for the fuel pump? if the pump is running then look at coilpacks, this is a common problem with these cars.

 

well, having no fuel coming through the lines leads me to believe that it's not working. The only thing that makes a noise when the key is turn'd to the on positionis a shiny metal box under the hood on the drivers side with vacuum lines coming off of it. Is there an EFI fus/relay located somewhere? where are the relays located at on this car? I can't seem to find them anywhere.

 

check engine to chassis ground wire for good contact and condition of the wire

thanks for the relay locations. I'm guessing that it's the same spot for the LHD version? What one is the EFI relay? thanks much.
