I haven't touched anything myself. Where exactly is the turbo actuator located? Is it something I can visually inspect for damage, or is it better left to the pros?

It's best to let a professional handle it. Given the symptoms, especially the stalling, it points to a more serious issue. The turbo actuator is buried pretty deep and requires specific tools and knowledge. You could end up causing more damage trying to DIY. It's almost certainly an electrical bypass valve defective. Take it to a workshop.

Thanks for the advice! I took it to the shop, and you nailed it. They confirmed the boost pressure actuator fault and replaced the defective electrical bypass valve. Cost me 250€, but the van is running perfectly again.

Sounds like a boost pressure actuator fault. That whistling and hissing combined with the power loss is a classic symptom. Have you checked the turbo actuator or any of the pressure sensors? Could be a boost control issue. Has there been any recent work done on the turbocharger?
