I have a Skoda Fabia Greenline 1.4 TDI, BMS and I just put a new EGR valve in it, cleaned out the visible soot, used a can of dpf filter cleaner (foam) to clean the dpf and got a new G450 Exhaust Pressure Sensor installed, and now I am getting the P0471 and P2002 code with the check engine light on and the dpf filter regeneration light on... The car runs well, rpm where it should be, acceleration as it should be... Could it be that the dpf filter is clogged up ? there are no visible cracks (or damage) on the dpf filter. Thanks in advance for taking the time to help me out!!!
