Hello and welcome,

My name is ***** ***** it will be my pleasure to assist you today.

Expert:  Steve replied 21 days ago.

the most likely cause of a no spark situation would be a failed crank sensor or problem with the ECU. I would start by replacing the crank sensor and then re-assess. From there, you would need a factory BMW scan tool or equivalent to preform additional diagnostic as a basic code reader will not be sufficient.

I have a snap on solus edge and get these codes : 2A3F valvetronic motor power supply.: 2A77 control unit internal fault valvetronic output stage.Does this help?
Expert:  Steve replied 21 days ago.

these codes suggest an issue with the valvetronic system but aren't definitive - could a control unit problem, power supply problem or sensor/actuator problem. not terribly common to cause a complete no start, though.
