Hi ALL
I've got a weird thing that happened to my d40 after coming off the canning stock route.
when i'm doing heavy acceleration ( so when the waste gate is fully open) it sounds like a really loud turbo whistle but stops as soon as you ease off.
i thought at first it may have been the turbo throwing in the towel but i had a look and wipe inside the the outlet pipe off the turbo and there is no metal fillings or anything so it's not the impeller rubbing.
i've checked the boost hoses they all seem in working order.
I'm still getting good power and full economy and the turbo is still whistling away nicely while driving normally.
also no oil stains/splatter in the engine bay so don't think anythings leaking
so if any one has any ideas please shear.
