Sounds like a DPF issue, I had similar symptoms with my Mini. Reduced engine power and smoke, especially when accelerating, are telltale signs. Has the engine light come on? I'd suggest checking the diesel filter first.

Interesting. Was it definitely the diesel filter in your case? And did you attempt a DPF cleaning, or did you go straight for filter replacement?

Yes, it was definitely the diesel filter causing my woes. I didn't try DPF cleaning; my mechanic advised against it, saying it's often a temporary fix. He suggested a filter replacement was the more reliable option in the long run. Perhaps a visit to a workshop is in order?

Huge thanks for the insights! It was indeed the diesel particulate filter. Vehicle inspection confirmed it. Ended up opting for a filter replacement since DPF cleaning didn't seem promising. Cost me 1550€. At least the engine light is gone and the Mini Cabrio is back to its old self.

Greit, jeg blir alvorlig frustrert. Min 2010 Mini Cabrio diesel gir noen fæle symptomer: redusert motoreffekt, og røykfaner når jeg trykker gassen i bånn. Jeg mistenker at det er et defekt dieselpartikkelfilter, men jeg er åpen for forslag. Noen tanker?
