Seat Leon exhaust noise and error

Louder exhaust and error codes? Sounds like those exhaust valves are sticking. Had a similar thing happen on my old Golf. Check the wiring to the exhaust components first, might be something simple. But yeah, exhaust flaps are a known issue. Is it just noisy at startup or all the time?

Thanks for the tip! Where exactly should I be looking for the wiring? I'm not super familiar with the exhaust system layout, but I'm willing to give it a shot before taking it to a workshop. Also, it's definitely worse on cold starts, but still louder than it should be when it's warmed up.

Okay, since it's worse on cold starts and still present when warmed up, it's probably not just a loose wire. The exhaust flaps themselves are likely the culprit if you're getting an error code related to the exhaust system. Honestly, unless you're comfortable working on exhaust components, it might be best to take it to a workshop. They can diagnose it properly and replace the exhaust flaps. It's a common enough issue they should know what to do.

Okay, perfect! I got it sorted. It was indeed the exhaust flaps like you said. Paid 190€ for the exhaust repair. Thanks a bunch for your help!
