When my W211 has the fan on (irrespective of whether the aircon is on or not - and I know the aircon is on even when turned off), I get a whirring noise which sounds like the transmission is straining under revs. When I turn the fan off altogether, the noise disappears (even when driving normally).
Is this the aircon pump on its way out? If not, is there a quick/cheap fix?
