Any ideas please, it’s driving me crazy. The engine is quiet until someone sits in the car then the shrieking starts. As soon as they get out it stops, same goes for sitting on the wing. I have attached a video if anyone has any ideas. Cheers Gary

I'm blown away 🤣 never known anything like it. I have no clue as to why the engine would make a noise due to more weight on the vehicle! Needs looking at properly mate 

Thanks all, took it to a friend who is a technician at Skoda. He was bamboozled too, but after a while found a small vacuum pipe that was rubbing on the driveshaft when yo7 sat in or on the car. The noise is the pipe sucking air in against the driveshaft😂 A quick new length of hose and clipped up out of the way has cured it! Thanks for all the hel, it was doing my nut in! Gary.
