Advice wanted: Problems with Opel Mokka 2014, diesel - loss of power, jerks and hisses, suspected defect in the swirl flap control system

Hey guys, need some advice on my Opel Mokka, built in 2014, diesel. It hasn't been running smoothly recently, shows a clear loss of power, jerks when accelerating and has a kind of hissing noise. It also shakes terribly when idling. The check engine light is permanently illuminated. I have a suspicion that it might be due to the swirl flap control on the intake manifold. Have any of you ever had similar problems? I'd be interested to know what you did to fix it and what your experiences were at the workshop. Thanks in advance!

Hello, I have had a similar experience with my Opel Meriva, built in 2012, diesel. I'm not exactly a mechanic, but have repaired a few cars. When my car had the same problem, I went to a trusted garage. It turned out that the swirl flap was broken. The repair cost me exactly 865.0 euros. Could you possibly provide some more information about your vehicle? More precise data could help to make a more accurate diagnosis. Hope this helps you!

Hey, thanks for your quick reply and sharing your experience. Sure, I'd be happy to give you more information. Well, my Mokka has now done exactly 61961 km and the last service was only recently. I'm really stressed because I thought I'd have peace of mind after the service. Well, it looks like I'll have to go back to my garage. Thanks again for the tip!

No problem, always welcome! It's definitely annoying, especially after a fresh service. What you describe definitely sounds like a problem with the swirl flap, like with my Meriva back then. Given the mileage of your Mokka, I could imagine that the swirl flap has simply given up the ghost. I would recommend that you don't wait too long and go to your garage quickly. Otherwise it could lead to bigger problems. Good luck and let us know how it goes! I'd be really interested to know if it was the same problem as my Opel. Take it easy and don't get too stressed!

Thank you very much for your advice and support! Will take the car to the garage tomorrow and yes, I'll keep you posted on what comes out of it. Hopefully it's nothing too bad that can cause repairs! Thanks again and I'll try to stay calm and not let it stress me out too much. Good night!
