Sprinter 519, need help dtc off and associated limp mode off too.

[morgano]

Here , nodtc no limp mod

Two days have passed since the file was burnt on the ecu. The van is working fine as of now. No more limp nor dtc, no lack of power,... also no other dtcs that could be waiting behind the p0172

Don’t know what to think now, faulty ecu or some ghost problem we cannot find that makes ecu think mixture is too rich.

Thanks ignasvw, you are top
