Mini Clubman engine power loss and smoke

I am writing to seek advice regarding a potential issue with my 2015 Mini Clubman, a diesel model with approximately 64020 km on the odometer. Recently, I have observed a noticeable reduction in engine power, accompanied by visible smoke when accelerating. I suspect a defective diesel particulate filter may be the cause. Has anyone experienced comparable issues? I am concerned about the upcoming vehicle inspection and any potential impact on fuel efficiency.

Sounds familiar! I had a similar issue with my Mini Cooper – not the Clubman, but same engine. The engine light came on, and it felt like I was driving through treacle. Is it still under warranty? Might be worth checking your exhaust system too. Good luck!

Thank you for your reply. Was the diesel filter the definitive cause in your case? And did you experience any issues with fuel efficiency beforehand?

Yep, it was the diesel filter. The garage confirmed it pretty quickly. Fuel efficiency went down the drain before the light even came on. Honestly, I'd get it checked out by a workshop ASAP. Don't want to risk further damage.

It appears that the diesel particulate filter was indeed the issue. The repair cost came to approximately 1550€. Hopefully, this resolves the problem permanently.
