Mini Roadster Diesel Power Loss and Smoke

Alright, need some advice. My 2012 Mini Roadster diesel is acting up. Major power loss, and she's blowing smoke like a chimney when I put my foot down. I reckon it's the diesel filter that's defective, but wanted to see if anyone else has had similar issues before I start ripping things apart.

Summary of the thread

A 2012 Mini Roadster diesel is experiencing major power loss and excessive smoke, suspected to be due to a defective diesel filter. The issue could also be related to the exhaust system or a sensor malfunction. Regeneration might help if the filter isn't too clogged, but a professional diagnosis is recommended to confirm the problem. Ultimately, replacing the diesel filter resolved the issue, restoring the car's performance.

Whoa, sounds rough! I had something kinda similar happen with my Mini Cooper, though it's a petrol version. Reduced power and a light on the dash – could it be related to the exhaust system somewhere? Did you notice any difference in fuel consumption or strange smells before the smoke started?

Cheers for the reply! Fuel consumption seemed normal, no weird smells either. When you say 'exhaust system', you mean like, the whole thing? Or is there a specific part I should be looking at? I was reading something about regeneration, is that worth trying?

Okay, so no weird smells kinda rules out some possibilities. When I said exhaust system, I was thinking maybe a sensor issue somewhere, but with the smoke, it really does sound like the diesel filter. Regeneration is worth a shot, but honestly, if it's really clogged, it might be too late. A garage should be able to test the filter properly though. If the engine light is on, they can read the error codes to confirm the issue.

Appreciate your help! Took it to a workshop and they confirmed the diesel filter was toast. New filter replacement, cleared the engine light, and now my Roadster runs like a charm. Cost me around 1550€, but worth it to get her back on the road.
