Seat Alhambra Engine Misfire
Summary of the thread
The 2019 Seat Alhambra experienced engine misfire symptoms, including rough starts, stalling at idle, and an illuminated check engine light. The suspected cause was a defective camshaft sensor, potentially due to a faulty encoder wheel on the camshafts. Sensor testing confirmed the issue, and a mechanic verified the faulty camshaft sensor and encoder wheel, leading to a successful repair.

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.
