Zohaib Posted May 12, 2019 Share Posted May 12, 2019 Hello, I have 2.0 TDI audi c7. I have engine management light on. When i scan for error codes i get dpf bank 1 above threshold. Recently, i got my dpf cleaned, i was told by mechanic that it wasn't bad but still he carried out forced regen and everything. -no limp mode -regenerates every 200-250 miles -soot mass calculated/measurd below 25g. -45mpg combined mileage (not bad) But i have noticed that sometimes soot mass measured goes in negative value. And at idle my dpf sensor voltage is above 1V. I dnt understand why my engine management light is on because of dpf although my car is not in limp mode i have done about 1000+ miles with warning light on. Could someone plz help me to get rid of engine management light? Thanks. Quote Link to comment Share on other sites More sharing options...

Envy Posted June 13, 2019 Share Posted June 13, 2019 With everything that you have said about the history of the regen it sounds to me like a sensor or wire fault. Quote Link to comment Share on other sites More sharing options...
