Hi All,

I have a strange whine comining from my air con system. Oddly it also happens when I turn air con off and just have normal ventilation running - but it is not as loud when the aircon is off.

It is not leaves in the system. The noise appears to be tied to engine speed.

Anyway, i'd like to attempt to diagnose myself but can't find any manual on line which would let me figure out how the cooling/ventilation system works.

Does anyone have such a manual (Bently Manual maybe) or can anyone tell me how to get hold of the ISTA/D software (I belive this will help..)

Thanks in advance,
John

Yeah, thanks. I have asked for a download link on the main ISTA thread a few days ago but haven't had a response yet.. I'm just being impatient.
