Mini Cabrio exhaust issue

Hello! I have a similar Mini Cabrio, though I cannot recall the exact year right now. I had a similar issue with increased exhaust noise and an error code popping up. It sounds like your exhaust flaps might be the culprit, especially with that mileage. Have you checked for any obvious exhaust blockage? It's like a clogged artery for your car, restricting the flow and causing all sorts of problems. Just a thought!

Thanks for the quick reply! An exhaust blockage is an interesting thought. How would I go about checking that myself? Is it something easily visible, or does it require special equipment?

In my case, the blockage wasn't immediately obvious. Given the symptoms and error code, it's highly likely the exhaust flaps themselves are the issue. They're designed to regulate exhaust flow and noise. If they are stuck, that will cause the louder exhaust noise. I would recommend taking it to a trusted workshop to confirm it. The 190€ estimate sounds reasonable for replacing the flaps, so you’re probably on the right track.

Just wanted to provide an update. I took the Mini to the workshop as you suggested. Indeed, the exhaust flaps were defective. The exhaust repair cost me 190€. The noisy engine running after cold start is now gone. Thanks again for your help!
