Just read on Internet about a company at Doncaster who remove the DPF from the exhaust system on any car and replace it with a straight through new Stainless Steel pipe.They also re programme the ECU ,and promise that you will never ever have a dash light warning or ant other problems with "Get you home mode" with the DPF .They also state that as we all use low sulphur diesel in the UK ,and a DPF is unnecessary in the UK .My mechanic says that the EU made these compulsory,to save the German car companies having to spend money on newer more efficient engines.
