Mercedes E Klasse Camshaft Sensor Issue

I'm hoping someone can offer some insight into a problem I'm experiencing with my 2002 Mercedes E Klasse with a gasoline engine. Lately, it's been difficult to start, and the engine sometimes stalls when idling. To top it off, the check engine light is now illuminated. I scanned it, and it's showing a defective camshaft sensor. I suspect it might be related to a faulty encoder wheel on the camshafts. Has anyone experienced similar issues? What could be the root cause, and what is the likelihood of a crankshaft sensor being involved? My initial estimate for the repair is around 695€, does this sound reasonable?

I have a similar E Klasse. I had the car stalling and check engine light too. It turned out to be the camshaft sensor. Did you check the sensor itself for any visible damage?

Thanks for the quick reply. I visually inspected the sensor, and it looks okay, no obvious cracks or damage. Could you describe in more detail what happened when your camshaft sensor failed? Were the symptoms exactly the same (car stalling, check engine light), or were there any other indicators? Was the crankshaft sensor involved at all?

Yes, the symptoms were identical: car stalling, check engine light. I did not have any crankshaft sensor issues. I recommend taking your car to a qualified mechanic to confirm the diagnosis and get it sorted.

I appreciate your input. I took your advice and brought the car to a workshop. It was indeed the camshaft sensor, or rather, as I initially suspected, the encoder wheel on the camshaft was defective, causing the sensor to give faulty readings. They replaced the sensor and the encoder wheel, and the car is running perfectly again. The repair cost was exactly as estimated. Thanks again!
