Dear Members,
I have noticed a little issue with my car W204 engine m271 1.6L kompressor.
The problem is that when I start the car in morning when everything is cold, the engine starts normal and after 1 min or so I see the rpm needle tries to drop suddently like the car will stall but it does not stall and the rpm is raised immediately. The car will heat up to temp and everything is normal.
If i switch off the car and restart while its hot there is no issue engine starts normal with low rpm.
I go error code PO335. Please did anyone had similar experience and what could be the main prob? since the runs fine but does this miss up only on cold start.

Thanks.

It’s the crankshaft position sensor.

I'm having the same problem with my car. Did you happen to be able to identify what the main problem would be?
