I am now fed up with my car regenerating every other week, and having to get an oil change at 1400 miles. I have now decided to remove the DPF, as I know it, combined with short journeys is the source of the problem. Has anyone had this done? I know that the car will have to be remapped when the DPF is removed. I will get a stainless steelexhaust manufacturer that I know to make a replacement pipe, and a company which I have used before to remap it. I will tell my insurance that I have reworked the exhaust, plus I will keep the original part for when I have to re-seel the car.
