Title: Powering the ECU for my B6 2.7T Swap... Need B5 S4 help Post by: AudiA4_20T on January 24, 2012, 09:33:23 AM Hey guys, so I have the car almost done and it's just about started
http://www.youtube.com/watch?v=4XdwODnsrfQ But it's not getting fuel, meaning the ECU isn't triggering the fuel pump relay, meaning the ECU might not be on, meaning that I might have my wiring wrong... Using this diagram (http://wiki.obdtuning.com/images/a/ac/VAG_ME7.x.jpg) I have pin 62 getting the 30 terminal, but it says pin 3 gets the 15 terminal (switched power), which looks like the black wire with the blue stripe. On the B6 the same wire seems to not go to switched power? Title: Re: Powering the ECU for my B6 2.7T Swap...

You should attempt to communicate with the ECU via NefMoto or VAG-COM to make sure it is powering up. Title: Re: Powering the ECU for my B6 2.7T Swap...

The stock harness just plugs into the ECU and shouldnt need touched. The connections all should be made at the 5 multipin plugs that join the engine harness to the car. |
