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.

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?
