2012 528ix Crank no Start

Kotletachka · 05-21-2019, 10:00 PM

F10 N20 engine. No Spark. Fuel pressure at rails and exhaust smells like fuel when cranking. Checked all fuses, grounds, removed and charged battery separately (battery is from 2018), rear power module on battery all good, spark plugs are new, wiring is good from DME to coil (back probed ohms, all good,) I dont have access to good wiring schematics (newtis.info only) but I did check both DME wiring to coil and power to coil. One was constantly jumping beitween 2.36-4.5V and the other was 0V regardless whether I was cranking or not. Coils are good. Only one fault code 1130:27 Ignition relay and fuel injector voltage low. Engine malfunction in Red and Stability error screen in car. Only things I can think of is a faulty power control module found under the passenger side hood or DME failure. The control module is constantly clicking when the car is on or cranking, and I dont thing its a power issue to the module. Any advice?

Last month i had the same problem with my 528 f10 with N52 engine. Furst it was thought to be the integrated supply module (ism or ivm). After replacing, it appeared that a faulty dme caused the problem. A bew one was ordered from Germany anf tge car was fixed after installing it. Good luck.
