I'm not sure if I'm supposed to get a whistle or maybe a small whine under acceleration but it's definately there. It's always been there, I've only noticed it more with my window being knackered and always being down about 5mm... (window now fixed... thank god!)..
Does anybody else get this from their oil burners? Power seems fine (nowt to compare it to) and it's only audible at low speed... Any thoughts?
