Since this morning, the MKL has been shining. When reading out, he says “lambda regulation outside tolerance” , which is a classic and has something to do with my gas system. But now, the “lambda probe – error signal” is new, which cannot be deleted. And not with the Delphi, the flashbox or by cohesion of the battery poles. Does anyone have a tip? Both to the background of the error and to the deletion. The probe is from Denso and approx. A year old.
