C240-Merc

Last week I had the Crank Position Sensor replaced by the dealer because the check engine light came on and gave the code for it. Today the check engine light came on again and gave the code P2017. The car seems to be driving fine, but the CEL and the code that it gave is making me nervous. I know that the P2017 code is: "P2017 Self adaptation of mixture formation from right bank1/2 of cylinder is at max/min limit at idle speed", but what exactly does that mean? Should I take it immediately to the dealer and will it leave me standing on the side of the road waiting for a tow truck?

I drive a 2001 C240 with approx. 77k miles.

Hello, I am new to this forum and also new to a 2004 C240 4matic. I have the same code as well as a p2088-001. Did you ever find a solution?
