My vehicle is a 2.2 cdti 184 ps and I love it to bits except for the constant (ie every 300 miles)the dpf is clogged, resultingin the coolingfans racing away after switching off, and the fuel economy drops through the floor after building up some good consumptionfigures. I am convinced that this can be programmed via the ecu to occur less frequently.By mapping it out to burn less fuel during warm upresulting in less soot for the dpf to deal with.Question:- can this forum bring any pressure on Vauxhall to relook at this very disappointing problem that is putting people off buying this vehicle. I know modern diesel engines have to have a dpf but not all are experiencing the same frequency of blocking up as this engine. I have friend with a Kia Sorrento who is also retired and does similar journeys to me and he hardy notices when the regen is happening so what is Vauxhalls problem.(apart from the car being built in South Korea and communication via G.M might not be as good as it could be)I welcome your comments.
