BMW 430d Gran Coupe - 2014
Just got this today in my car while parked up at home. Car won't crank or start.. Will attach Carly diagnostic screenshots in next post. I thought it could be the high pressure fuel pump but I'm seeing a lot of DDE errors? |

DDE relay ordered just in case. I've had a look at the wiring diagram on newtis.info and I don't believe it's any of the fuses either.
Can someone confirm what wires are positive and ground for the DME? |

Ok so I put a new relay in but no luck. I got my circuit tester out and can confirm that:
1. I have power coming in to the DDE relay in pin 4 and out of pin 8 (DDE wake up signal) 2. I have power coming in to the DDE relay in pin 6 but not out of pin 2. This should be providing the main power to the DDE. Bit confused what to do now as I just ordered a new relay directly from bmw (I'll find a way to test its functioning. I know if I jump the connection everything will probably work. |
