Skoda Rapid Diesel Engine Problem

My 2010 Skoda Rapid diesel is giving me headaches. Check engine light's on, and it feels like it's lost a lot of power. Engine response is terrible. Also, there's a whistling noise, plus a loud hissing sound when I accelerate. Sometimes the engine stalls when idling, and fuel consumption seems higher than usual. Could this be the boost pressure actuator valve?

A 2010 Skoda Rapid diesel exhibited issues such as a check engine light, power loss, poor engine response, whistling and hissing noises, stalling at idle, and increased fuel consumption. These symptoms suggested a potential problem with the boost pressure actuator valve or a boost leak. After inspection, a mechanic identified the issue as a faulty electrical bypass valve, which was replaced, resolving the problems and restoring the car's performance.

Whistling and hissing sounds point to a boost leak. Have you checked all the hoses and intercooler connections? A loose clamp could cause those symptoms and the reduced power.

I visually inspected the hoses, but couldn't find anything obvious. Could a faulty pressure sensor cause similar issues, or is it definitely a boost leak?

Stalling at idle points away from just a simple hose leak. A defective actuator valve or a problem with the turbo wastegate could cause those symptoms. It might be best to get it checked by a professional.

Took it to a mechanic. They confirmed it was the electrical bypass valve. Replaced it, total cost 250€. Runs like new now. Thanks for the advice.
