But DPF problem is with literately all cars that has DPF on it. As mentioned by Michael you cannot drive these cars in town for long, but this was the small print which was never raised up when you select the car and buy the more expensive diesel engine one to save up on fuel. Regeneration means you need to drive the car on a motorway for 20 minutes with more than 2k RPM -- this one barely reach this at 70mph (which is the legal speed limit here in the UK), so you need to shift down to 5 or even 4 -- but then again, burning more fuel just to save up environment is just not right! Also they say in regeneration process the computer pushes more fuel to increase the temperature in the DPF system. This system is plain wrong in my opinion.
