Puma exhaust flap error

Interesting issue. I also own a Puma and had some similar symptoms. Louder exhaust noise, definitely. Though I didn't check the error memory. I am not sure but could it be related to the flap motor or perhaps blocked exhaust valves?

Thanks for the response. When you say 'similar symptoms,' do you mean the error code as well, or just the exhaust noise? And were you able to resolve it? How much did it cost?

I must admit I never checked for an error code. I noticed the noise and took it to a workshop straight away. They quickly identified it as the exhaust flap motor causing the issue. While I am unsure of what caused it, they did mention blocked exhaust valves as a possible cause. I would definitely suggest you get it checked by a professional.

Thanks, I appreciate the advice. Ended up being exactly as you suspected: the exhaust flap was indeed defective. The repair cost 190€ to fix, replacing the flap motor resolved the issue.
