Yes, I did some sensor testing with a multimeter, checking for voltage and resistance, and the values were off compared to what the service manual stated. Plus, I borrowed a professional-grade scan tool from a friend, and it threw a specific code related to the camshaft sensor. But I'm curious, what was the root cause in your case with the Insignia?

Ah, if you've already done sensor testing and pulled a specific code, it definitely points towards the camshaft sensor. In my case, it was also the sensor itself, but it turned out to be triggered by a broken wire in the harness leading to the sensor. But if you suspect the encoder wheel, I'd say it's best to get it checked out at a workshop. Don't want to risk further engine damage.

Just to finalize this, a trusted mechanic confirmed the camshaft sensor was faulty. The encoder wheel on the camshafts was the issue, as suspected. The repair cost 695€, which isn't ideal, but the Alhambra is running smoothly again. Thanks for the input!

That sounds familiar! I had a similar issue with my Opel Insignia a while back. Engine misfire, stalling at idle, check engine light – the works! Did you try any sensor testing to confirm it's the camshaft sensor? Engine control units can be tricky, and sometimes the symptoms can point to the wrong thing.
