>concerning the AC... aside from the famous clunk which changes in loudness >due to outside temparature.... i also have a occasional intermittent (every >2-3 minutes) hissing sound when AC is engaged. Still no comments on that >one from the dealer aside from it's normal. The 'hissing' noise is the expansion valve (TXV) opening and closing, the function of the valve is to give the desired amount of refrigerant to the system (I would guess that this is a concern on cars used in temperatures ranging from say 15C to 25C, when warmer the AC is running full open?!) The noise is 'in' every valve but of course due to tolerances in the spring dampening the valve the noise is more or less frequent (and also depends on the ambient temperature). Replacing the valve might help but it is not a guarantee. I know that the diesel engine have a stiffer spring might be worth asking for a replacement?
