Well, turbo is on the left. hoses to intercooler and from there, left side to the engine. I replaced it all with stainless steel piping and silicone hoses some years ago.
I changes the noise somewhat when I squeeze the silicone fittings/hoses.
But not in a way that there might be the problem.
What is there is the EGR. I had a problem with it once. 17" year after end of the warranty. So should have been around 25-30k km.
Also you hear often from whistling noises if the gasket of the EGR is defect. But more to a whistle with higher rpm and constant whistle.
But all the hints, no powerloss, noise since 2 years 15k km and becoming only worse slowly, nor error in the system, direction were noise is coming from.........
I´m not in the mood right now to take apart half of the engine, but I think I will give dealership a good description and point to the EGR.
