The DPF issues begin

So where do I begin with this dire experience of both a Range Rover Sport and Land Rover Customer Services.

After a few months of owning the car I began to get frequent DPF warning lights after driving my vehicle between 400-500 miles. Most people reading this will know what a DPF is, but essentially it is a filter in the exhaust which collects diesel particular matter. Once the filter has collected a certain amount of soot the car needs to carry our a regeneration by effectively burning off the soot collected in the filter. This is usually achieved by driving the vehicle at motorway speeds for 15-20 minutes after which the warning light dissappears and the filter has been cleared. Under normal circumstances a regeneration should be easily achieved and if not the vehicle develops a loss of power requiring it to be recovered to a dealer in order to be fixed.

So after having several DPF warnings in the first few months I was frequently taking my vehicle for late night drives, often upto 60 miles in order to achieve a regeneration. Eventually after a few months of ownership I required the services of Land Rover Assist to visit me at home and force the DPF to regenerate.

The problems with my DPF progressed over time and the intervals between a successful DPF regeneration and a recurrence of the DPF warning gradually reduced. My car was recovered into my local Land Rover dealership where I was told that my vehicle has no issues, and my driving style was responsible for the DPF blockage in my car.

Now as a Land Rover owner I have been somewhat forced to become a passive expert in DPFs, and was well aware of the type of driving required to ensure a clean and healthy DPF. Whilst I do a mixture of journeys I ensured I always carried out at least one journey a week where the DPF would have sufficient opportunity to carry out a regeneration.
