Buzz inside dash.
My 147 8v diesel has developed a buzz inside the dash somewhere. To me driving, it sounds like it's coming from the passenger's window side round air vent area, but to a passenger it sounds like it's coming from mine, so I guess it must be somewhere in the middle.
It is easy enough to take the air vent cluster in the middle of the dash out, so I can have a poke around inside? If so, how do I get it off?
Has anyone else had anything like this and can give me some pointers?
The biggest obstacle to tracking it down is that it only happens under hard acceleration at just under 2,000 RPM.
