Mini Roadster diesel power loss

Alright, petrolheads, I've got a bit of a pickle with my 2015 Mini Roadster diesel. It's got some kilometers on the clock, and recently, I've noticed a serious drop in engine power. Hooked it up to a scan tool, and it's showing an error stored in the error memory. I reckon it's got something to do with that dodgy chip tuning I had done by some third-party cowboys a while back. Anyone else experienced this?

I had something similar happen on my Mini Roadster. What fault code did the scan tool pull up? Did the check engine light come on? It sounds like a fueling issue maybe?

Interesting! Yeah, the dashboard light was on, and the car diagnostic showed reduced engine power. How did you resolve your issue? Was it definitely the fueling? Any specifics on the code your car computer displayed?

Yes, that sounds very similar to what I experienced. I took mine to a workshop and they indicated that the remapping had caused the ECU to enter a failsafe mode. I would recommend having it checked out professionally.

Thanks a bunch for the help! Took it to a reliable mechanic, and you nailed it – the car computer threw a code related to the dodgy chip tuning. They reset everything to the factory settings, and now my Roadster purrs like a kitten again. Cost me 180€, but it's worth it to have the old power back!
