Evanda exhaust flap issue

Hey, I've got a 2003 Chevrolet Evanda with a gasoline engine and I'm running into a weird problem. The car has around 71525 km on it. I keep getting an error related to the exhaust flaps. I've also noticed the exhaust is louder than usual, and the engine sounds pretty rough, especially when it's cold. From what I've read, it sounds like the exhaust flap motor might be defective. Has anyone else experienced something similar?

I had a similar issue with my Evanda some time ago. Loud exhaust, error codes popping up... Sounds like your exhaust flap is indeed on its way out. Have you checked for any visible damage or blockages around the exhaust components?

Thanks for the quick reply! I haven't had a chance to visually inspect it yet, but I'll take a look tomorrow. When you had the issue, was it a constant loud exhaust, or just at certain times? And did you end up replacing the whole exhaust system, or just the flap motor?

Mine was intermittent at first, then became constant. I tried fiddling with it myself, but honestly, access is a pain. In the end, I took it to a workshop. They confirmed it was the flap and replaced it. I'd suggest getting it properly diagnosed; could save you time and hassle in the long run.

Thanks a lot for the advice! I'll take your word for it and book it in with a mechanic soon. Turns out the exhaust flap was indeed defective. Cost me around 190€ to get it sorted, but the car sounds much better now.
