Skoda Roomster Diesel Engine Problems

My 2015 Skoda Roomster diesel is giving me grief. I'm experiencing reduced engine power, rough running, and a jerking sensation when accelerating. There's also a loud hissing noise when I put my foot down, and the fuel consumption seems higher than usual. Could a defective intake manifold flap control be the culprit?

That sounds rough! Reduced power and jerking aren't fun. Does the hissing sound change with engine speed? A faulty manifold flap could mess with the air intake and cause those symptoms. I would be worried!

The hissing does get louder as I accelerate. How can I be sure it's the manifold flap control before I start replacing parts?

If the hissing gets louder with acceleration, it definitely points to an air intake issue related to the manifold flap. A diagnostic check should confirm it, but all the signs suggest it's faulty. I recommend taking it to a workshop.

Thanks for the insight. The workshop confirmed it was the intake manifold flap control. Cost me 465€ to get it sorted. Engine performance is back to normal now.
