I'm pretty sure I have a turbo leak somewhere as my car is making a 'whooshing' sound under acceleration which sounds like it's coming from on top/in front of the dash. It was in with a mechanic yesterday for something else entirely and, as an aside after a test drive, he mentioned to me that he thought it might have a leak somewhere in the turbo system also. It's chucking out a bit more smoke than usual (it's a diesel), so would this mean it's burning more fuel? And would this indicate a leak too i.e. burning more fuel to give the same power?
Are there any 'usual suspect' areas where the turbo system develops leaks? It's a 1.6tdci
