Corvette Camshaft Encoder Wheel Defect

That sounds familiar. I had similar issues with my 2018 BMW 3 series. Same symptoms: rough starts, stalling, and the dreaded check engine light. In my case, it turned out to be a faulty crankshaft sensor messing with the ignition timing. Have you checked that, or just the camshaft sensor?

Thanks for the tip! I haven't specifically checked the crankshaft sensor. How did you narrow it down on your BMW? Was it difficult to diagnose, and was the camshaft position impacted?

It was a process of elimination, really. The mechanic initially suspected the camshaft sensor as well. Sensor testing ruled that out. Eventually, they discovered the crankshaft sensor was sending incorrect data, throwing off the entire system. It might be worth having your sensors properly tested before assuming it's the camshaft sensor. In my case, camshaft position was affected because the timing was off. I would recommend going to the workshop before doing more damage.

I appreciate the advice. I took it to a trusted workshop. Turns out I was right, a defective encoder wheel on camshafts was the problem. Repair cost 695€ Thanks again for sharing your experience!
