DPF warning light

Problem:

If the DPF (Diesel Particulate Filter) warning light has appeared on the dashboard, then it is usually caused by a blocked DPF, due to the car only being driven around town. This means that the DPF is unable to reach high enough temperatures ,to be able to burn off the unwanted particles. This results in the DPF becoming blocked.

Solution:

You need to take the car out onto a motorway and drive it in 4th gear, at about 2500 rpm for about 10 miles. This will allow the DPF to get hot enough, to be able to burn off these unwanted particles. This in turn, should cause the warning light to go off on the dashboard. Have a look at the video below, for an idea on how to do this:
