Expert diesel particulate filter issue

Sounds like the dreaded DPF issue. I had something similar with my Expert. Engine light came on, felt like I was towing a boat anchor, and saw a cloud of smoke behind me when I put my foot down. Has your fuel efficiency tanked as well?

Indeed, fuel efficiency has decreased noticeably. So, the symptoms do match. What was the eventual diagnosis and resolution in your case?

Yep, sounds like DPF backpressure is the culprit, likely defective. I tried a forced regeneration, but it didn't help. Eventually, the workshop confirmed it needed replacing. Think of it like a clogged artery; the engine can't breathe properly. Bite the bullet and take it to a workshop, that's the best I can advise.

Thank you for confirming my suspicions and sharing your experience. The workshop has also diagnosed a defective DPF. Replacement cost is quoted at 1550€. I appreciate your help.
