ESP light on and injector drift warning
Hi guys,
My C220 CDI (W204-008) has the ESP light on and went into limp mode and the engine runs rough at idle. After diagnosis I get the following fault codes:
2071 injector drift cylinder 1 the lower limit value is reached
7201 One or more signals sent from control unit Engine Control module via the CAN bus is implausible
I can understand that in diesel cars, since the torque is controlled by the amount fuel injected, it sounds logical to get ESP fault because of a bad injector. Is this correct? Is the injector gone really bad or can I run an injector cleaner to see if it fixes the issue?
Thanks in advance

Hi I'm having very similar problems with my C220 Cdi Sport, and just got the same 2071 code also. I've started a thread if you'd like to keep an eye on it, as I shall this one.
Good luck!
