You could try giving the motor a long run in low gears and high revs to get the exhaust really hot and hopefully clear out your DPF,if not it will need to go onto the correct computer to be regenerated,if that doesn`t work then you could be in for a really big bill if you need to replace your DPF filter. If you do a lot of town driving then either give the motor a long run every weekend or sell it and buy a petrol motor.
