I get a whinning metalic noise when a/c turned on.

I can feel it from the steering.

It not very loud but just annoying.

When I open the bonnet I cant hear the noise outside as in the cockpit.

Any suggestions?

Check the AC pulley, on my daughters E30 the pulley was whining and I lubed it with something like WD-40, but more of a rust breaker lube in a aerosol can. So far no further noise. Also, how tight is the drive belt on the AC pulley?
