Hi All

I’m having an issue with my 2011 W221 Bluetec going into limp mode. I had the codes read, which there were a couple. 1 related to the egr valve and another was an intermittent fuel pump code.

I’ve cleaned the egr valve, and I’ve also changed the fuel filter as looking at the service record, this hasn’t been done for some time.

My question is, having done these things, would I need the car plugged in to a star system machine to reset something or other, as she’s still in limp mode

Thx
