The DPF on my 2010 Ford Mondeo TDCi burnt out, glowed red, smoked and then the exhaust dropped after 109,000 miles. No warning lights came up on dash. Can I just replace the DPF or do I need to sort out the ECU in any way? I do short trips to work during the week but a few trips out at the weekend. I've had the car for four years with no problems, so £210 for a new DPF is okay.
