Citroen DS5 diesel particulate filter issue

I had similar symptoms. I also have a DS5 diesel. It could be the DPF. How often do you drive it, and what type of journeys do you usually undertake?

Thanks for the reply! I usually drive it a couple of times a week, mostly short trips around town. Could that be the problem? What was the cause in your case?

Yes, short journeys are not good for DPF regeneration. My issue was a defective DPF requiring replacement. I recommend a vehicle inspection.

Thanks a lot for the advice! I took it to a workshop, and you were right - the diesel particulate filter was defective. The repair cost me 1550€. Appreciate your help!
