Grandland X Exhaust Flap Issue

I have a Grandland X as well, and your situation sounds eerily familiar to what I experienced some months ago. I noticed a change in the exhaust note, almost a raspiness, and also observed a slight decrease in overall engine performance. Did your mechanic happen to mention anything about a potential exhaust blockage? It might be beneficial to check for any unusual restrictions within the exhaust system, as this could also contribute to the error you are seeing.

Thanks for the reply. My mechanic mentioned a possible malfunction in the exhaust flaps, but didn't elaborate on any potential exhaust blockage. Are you referring to a blockage upstream or downstream of the exhaust flaps? Also, did the error memory point to a specific issue with the exhaust system, or was it a more generic engine fault code?

In my case, the blockage seemed to be connected to the exhaust flap mechanism itself, restricting its movement and triggering the error code. While I am not a qualified mechanic, it seemed plausible that the flap was sticking, leading to increased back pressure and the altered exhaust sound you're describing. Given your symptoms and the stored error, I strongly recommend having a workshop examine the exhaust flaps and the surrounding area more closely. Continuing to drive with a faulty exhaust system can potentially damage other engine components.

I appreciate the detailed feedback. Based on your experience and the mechanic's initial diagnosis, I've decided to proceed with replacing the exhaust flaps. The total repair cost came to 190€. Thanks again for your assistance and insights into this irritating exhaust noise issue.
