Audi A4 3.0 TDi CCWB 2009 - Unable to reset DPF Soot Level Post Clean, MIL on - Fixed #
Posted by Christopher Taylor on November 30, 2016, 11:42 am This Audi has according to our local DPF cleaning services had its filter successfully cleaned. Testing the pressure in the exhaust before and after confirmed this.Using the Bosch KTS I re-adapted the values for the DPF, Catalyst and Pressure sensor which was changed also. When the flashing glow light remained, it continued to run in limp home and had two permanent fault codes for: P246300 Diesel Particulate filter overloaded and P200200 DPF Faulty Operation. I presumed that the control unit needed to relearn some values on a drive cycle and all would correct its self providing there were no gas temp sensor, lambda or other sensor faults.
