Customer Question
I keep gettin the...

I keep gettin the same 2 codes on my 2015 4cylinder diesel, they are "u040ffb & p261f71". It runs fine and i'm still getting great fuel mileage. I'm just tired of looking at this stupid light. my local garage says they can't figure it out either. I actually took it to the mother ship "Mercedes" and they couldn't give a good answer.

Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about?

Check Engine

Mechanic's Assistant: What is the model of your '15 Mercedes?

Yes, sprinter crew van

Mechanic's Assistant: Are you fixing your Sprinter yourself? What have you tried so far?

Originally i was told it was the EGR, which I had changed by a professional garage.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I'm just trying to find out what these codes are. I have a Mercedes Code Reader and it says these codes are not in the library. It would be nice if there was a place that listed all the codes.
