Guys
I have a 1.8 turbo R75 (2002, 65k miles) and after 3 months I'm very happy with it, apart from ...
... there's this noise on acceleration, it's sort of like a hissing but kind of metallic as well. Imagine someone spinning two flat metal plates together. It seems to be linked to throttle opening and engine load rather than speed or revs because it goes away when you lift your foot off the gas - even slightly.
A friend (non expert) suggests a noisy turbocharger. Anyone else had this noise? It's always been there since I had the car, doesn't seem to affect performance other than the fact that I tend not to push the car too hard to avoid hearing the din so it's probably saving me loads of petrol
