Sprinter diesel engine misfire problems

I had something similar with my Sprinter, also a diesel. Rough idling, plus the check engine light drove me nuts. They ran some sensor testing and found a faulty camshaft sensor. Could also be ignition timing if the sensor is sending bad info. Is it throwing any specific codes

It's throwing codes related to the camshaft sensor. I'm thinking sensor failure is most probable. Did replacing the sensor fix it, or was there more to it

Replacing the camshaft sensor resolved the issue. The mechanic mentioned the encoder wheel on the camshafts can also cause similar problems. It's best to get it checked at a workshop to be sure

That's helpful. It ended up being the camshaft sensor and also the encoder wheel was defective. I was quoted 695€ for the repair. I appreciate the insight
