I have a bmw 318i n42 with a starting problem. When you crank engine it doesnt start and shows low compression on all cylinders (around 90psi) but strange thing is that if you unplug the valvetronic motor it builds compression and starts right up and runs fine. No fault codes in dme/ecu. Tried a new valvetronic motor, reset valvetronic adaptations etc. but same starting problem remains. What could be the cause?
