Hi All,
there's a funny electrical "humming" or "whining" noise coming from the under the bonnet of the Saloon. Further investigation shows it to be coming from a largeish cylindrical object, which has vac hoses going to it. This object is situated in the drivers side inner wing, just below the power steering resevoir. The humming stops if I take one of the vac hoses off, or turn the engine off (obviously!) It's not apparent at idle..
So.. my question is..
what is this thing? why is it making a noise? how can I stop it?
Thanks!
Mike
