Nemo exhaust flap issue

I'm having trouble with my 2012 gasoline Citroen Nemo, which has 53013 km on it. I think the exhaust flaps aren't working right. There's an error code, the exhaust is louder than usual, and the engine is noisy after a cold start. Could a bad exhaust flap be the problem?

A 2012 Citroen Nemo is experiencing issues with the exhaust system, indicated by an error code, increased exhaust noise, and a noisy engine after a cold start. The problem is suspected to be related to malfunctioning exhaust flaps. It is suggested to check the flap motor for power issues, but due to the complexity, a professional diagnosis at a workshop is recommended to confirm the cause and determine the appropriate repair.

I also have a Nemo, though I'm not sure of the year. Your symptoms sound familiar – louder exhaust, especially at startup, and a code about exhaust parts. Have you checked the flap motor itself? Is it getting power?

Thanks. No, I haven't checked the motor directly, and I'm not sure how. Is it easy to get to, and what voltage should I look for? Could something else be the cause, or is the flap most likely?

Accessing the motor can be tricky, depending on your skills. I'm not qualified to advise on voltages or testing. But with those symptoms and the error code, it really sounds like the exhaust flap or its motor. To be safe, I'd get a professional diagnosis at a workshop.

I appreciate the input. I'll book an appointment to have it checked. I'm guessing the repair will be around 190€, and I'll let you know if that changes. Thanks again.
