As many of you will know I have had the DPF and CAT removed from my car. The car runs well and the fuel consumption is very good, However I do have one problem. When I accelerate hard when the temperature is cold, damp or wet I get the engine light coming on. The code is P2453 which relates to theDPF which I know is not in the car and is supposed to have been written out in a remap. After speaking to the person who did the remap I have been told to get the ash content removed via the dealers diagnostic equipment. I know that I can reset the light myself however I would like to get to the bottom of the problem. I have been told that there should be probes under the car, my plan is to find them, insulate them and weatherproof them, has anyone else had this problem? PS my car does not go into limp mode, indeed I think that it runs better when the light is on!
