ignition relay confusion E90 320 2006

[RoVic]

Hello, been having problems with a none starter! at first we thought it was to do with the fuel pump but that now been ruled out. it now seems likely its a fault in the ignition system its been tested and seems theres only 6v being delivered to the ignition Coils. been trying to locate the ignition Coil relay to replace but the wiring and relays diagrams don't really explain where the relay is? could someone please point me in the direction of it !!

I don’t think it has a relay - it’s switched via the dme. Their is a fuse in the E box with the dme the gives the feed that might be worth checking to see if u are getting 12v at that point. Is the coils earth ok on the top of the rocker cover and main engine earth as well? Good chance it’s the dme itself though

Thanks for the info Elliot2000.
we checked the volts on the fuse in the E box it gave a reading of only 8V. elsewhere in the engine compartment its12v . its beginning to point towards the DME !!
