    Hi all !! When I hooked my scanner to diagnose no crank no start issue of this bmw 5 series f10 (f07), I did not have communication with ECU ( DMA) of the car!

    The ECU temperature sensor, is that normally open or normally closed with regards to its resistance? I believe my temp sensor is bad. Reads 0.0 Ohms so it is closed. Regardless if it’s in near boiling water or sitting on a block of ice it’s reads closed. The reason I think the ECU temperature...
