Been a while since the DPF was removed so here is an update of things so far. The car was running great apart from too much black smoke on acceleration [unburnt diesel]. They took the car back in to check it out, they found the EGR valve was passing and have now blanked it off . Also my car had been re-mapped before its DPF removal and second remap at filter removal. Sothey reverted the car back to standard original mapthen re-mapped again with DPF removal to remove any conflict. Car still is running great but without the excessive smoke. Was in the middle of a brim to brim mpg check so will have to save up again to fill back up to the top and start again. The EGR passing alsoplayed its part in the excess soot blocking the DPF on the original problem !!!
