Mini Paceman problems with the engine, engine indicator light keeps coming on

Exhaust leak

Hey guys, my Mini Paceman Diesel (2013 model year) is causing problems and I need your advice. I've noticed the following symptoms: black smoke when accelerating, check engine light on, loss of power, exhaust leak and strong exhaust smell. I think there might be something wrong with the exhaust aftertreatment. Have any of you had similar experiences? How was the problem solved in the workshop and what tips do you have for me? Thank you!

Hey, I had a similar problem with my Mini Countryman (2015 model year). I also had the check engine light on and there was a loss of power. After the check in the workshop, it turned out that one of the lambda sensors was defective. The repair cost me 375.0 euros. I have little experience with cars, so I left the problem directly to my garage. They replaced the lambda sensor and the car has been running smoothly ever since. Could you share some more information about your vehicle? We might then be able to give you more precise tips. Best regards!

Hey, thanks for the quick reply! My Mini Paceman Diesel is at 105432 km and the last service was about 3 months ago. Apart from the symptoms I mentioned, it's actually running smoothly. I hope this helps. Best regards!

Hey, that sounds pretty annoying. I once had similar problems with my Mini Paceman Diesel (same model series), but at 98000 km. In my case, it wasn't just the lambda sensor, but also a clogged diesel particulate filter (DPF). The strong exhaust odor and black smoke in my case indicated that the DPF was no longer working properly and too much soot was accumulating. First of all, I would advise you to have a precise diagnosis carried out in the workshop. They could check both the lambda sensors and the DPF. In my case, cleaning the DPF and replacing the faulty lambda sensor cost around 450 euros in total. After that, the car ran perfectly again and the check engine light went out. Maybe it's a similar case for you. Be sure to keep us up to date with what the workshop says! Good luck and may your Mini soon be running perfectly again! Best regards!

It sounds like an exhaust aftertreatment issue to me. I suggest taking your Mini Paceman to a certified mechanic for a thorough diagnosis. Common fixes include replacing the DPF or EGR valve. I would also ensure all components are checked for leaks. Good luck!

I’ve got a mini 2012 hatch one 1.6 first LCi model. It’s just flagged up a code 00276A It’s says it’s related to the catalyst converter. I’ve just had a new catalyst converter replaced and front of the exhaust too. Only done 200 miles since it’s been replaced. Any help much appreciated

Hello JoeMini87, It sounds like the error code 00276A in your Mini, shortly after replacing the catalytic converter and exhaust, might be due to issues such as improper installation, faulty oxygen sensors, or exhaust leaks. Ensure everything is correctly installed and all connections are secure. Consider checking the oxygen sensors and for any leaks in the system. You might also need to complete more driving miles to allow the vehicle's computer to reset fully. If the problem persists, rechecking the diagnostics and consulting with a mechanic would be advisable, especially if the replacement parts are under warranty. Let me know how it goes or if you have further questions!

Let our mechanics help you!
