J 271 Relay Location Audi A 3. Porsche cayenne main ecu engine computer ECM dme relay location replacement. When I got home I yanked out the fuel pump relay and swapped it out with one from AutoZone around the corner.
The Audi service bulletin states that the root problem is the ECM power supply relay. When I got home I yanked out the fuel pump relay and swapped it out with one from AutoZone around the corner. Looks like it supplies quite a few things, so is probably rated for quite a lot of amps.

One on the fuse box is located in the dashboard driver's side and another one in engine compartment - battery. They seemed to want to charge an arm. It's also a good idea to check the relay socket wiring to or from the fuse box. and my reverse light has gone, I brought a reverse switch not sure where the location of this is either, I'd be grateful for your help, many thanks.
