Mini One engine power loss

I may have encountered a similar issue with my Mini. Engine idling was rough, and the check engine light illuminated. Have you checked the air flow sensor? A malfunctioning sensor may cause the throttle body to not function correctly. I am uncertain if it would resolve it, but it may be worth investigating.

Thank you for your input. Did you also experience a reduction in engine power? Was the check engine light consistently on, or did it appear intermittently?

Indeed, I experienced diminished engine power, and the check engine light remained consistently illuminated. Given your symptoms and the estimated replacement cost you mentioned, it is conceivable that the throttle valve is indeed the source of the problem. I would advise consulting with a qualified technician for a thorough assessment.

I appreciate the assistance. I took the Mini One to the workshop, and they confirmed the throttle valve was defective. The replacement cost was 265€, as anticipated. The vehicle is now running smoothly again.
