VW Eos Rough Start & Stalling: Cam Sensor Troubles

I had a very similar issue with my 2011 VW Golf 2.0T last year. Having worked on several VW engines, I can share some relevant experience about this. The symptoms you describe match exactly what I encountered, rough starting, stalling at idle, and the check engine light. The initial diagnosis from my mechanic revealed the encoder wheel on the camshafts was defective, which directly affects the camshaft position readings. The total repair cost was 695€, which included: Complete diagnosis, Parts replacement, Labor costs, Sensor testing and recalibration After the repair, all issues were resolved and the engine control system returned to normal operation. The car runs perfectly now with no stalling or rough starts. Before proceeding with repairs, could you share: Any diagnostic codes you retrieved? Does the issue occur more frequently when the engine is cold or warm? Have you noticed any unusual sounds from the engine? Are there any other warning lights besides the check engine light? This information would help determine if your issue is identical to what I experienced and could save you time and money in diagnosis.

Last service completed at 138000km. I had exactly the same symptoms you mentioned, stalling, rough idle, and check engine light coming on out of nowhere. Had my mechanic run diagnostics and got P0341 code pointing to the camshaft position sensor. The repair cost was around 280€ total, most shops charge 1-2 hours labor plus parts. Engine control system worked perfectly after replacing the sensor. Worth checking if oil changes were done regularly since dirty oil can damage these sensors. Important to know: had to clear the engine codes after the fix to get rid of the check engine light. No issues since then, running smooth for the past 6000km. Common question about cold starts, mine actually ran worse when warm. Important to get this fixed soon since the car might not start at all if the camshaft sensor completely fails.

Good to hear you got it sorted out. My experience matches yours exactly, I also got the P0341 code on my VW Golf before replacing the camshaft position sensor. The symptoms with stalling and rough idle were incredibly similar. One thing to add, after my repair, I made sure to stick to a strict oil change schedule using the recommended oil grade. A mechanic explained that contaminated oil can damage these sensors over time. The check engine light hasnt returned in over 15000km of driving. The crankshaft sensor is worth checking too while doing this repair. Sometimes both sensors can deteriorate around the same mileage point. My mechanic tested both but luckily only the camshaft sensor needed replacement. Your repair cost of 280€ sounds about right. I paid slightly more at my shop but included some additional diagnostic work. The important thing is the car stalling issue is completely resolved and the engine runs properly now. For others reading, when the check engine light comes on with stalling symptoms, getting the sensor codes read early can save a lot of troubleshooting time. These sensors are a common failure point on our engine type.

Thanks for the helpful details about your Golf repair. Just had my Eos back from the shop today and wanted to share the outcome. Got the P0341 code pulled and confirmed it was indeed the camshaft position sensor. Repair cost matched what others paid, 290€ including parts and labor. The sensor failure symptoms matched exactly what you described. My engine control system is working perfectly now. The mechanic showed me the old sensor and you could see visible wear. Found out regular oil changes really do matter for preventing premature sensor failure. The crankshaft sensor checked out fine during testing. Shop checked both sensors as a precaution since they often fail around the same time. Good advice about getting codes read early, saved time pinpointing the issue. Car starts great now, no more stalling or rough idle. Cleared the check engine light after the repair and it hasnt come back. Planning to stick to a strict maintenance schedule to avoid future sensor issues. For anyone searching later, if you get similar symptoms with code P0341, the camshaft position sensor is likely the culprit. Getting it diagnosed early prevents bigger problems down the road.
