Mokka Exhaust Flap Issue

Whoa, sounds familiar! I have a Mokka too and had something very similar happen. Louder exhaust, especially at startup. Did you check if the flap actuator is working properly? Could be an exhaust blockage issue, maybe affecting the exhaust valves?

Could you elaborate on the flap actuator? I'm not familiar with its function or how to check it. Also, were your symptoms exactly the same, especially the error memory issue?

Yep, exact same symptoms, error code and all! I'm no mechanic but I think the actuator controls the exhaust flaps, makes 'em open and close to manage backpressure. When mine failed, the flaps were stuck open, hence the noise. Honestly, I'd suggest a workshop; fiddling with the exhaust system can be tricky.

I appreciate the confirmation and advice. I will schedule an appointment with a qualified technician to inspect the exhaust flaps and actuator. Thanks for your assistance.
