I get whirring noises at specific engine speeds, and these change when the air con is on.
Makes me wonder whether it is the clutch rather than the compressor. I see it comes apart. Is there a bearing or something in there than can be replaced?
On the other hand, the air con has no effect so I assume there is now no gas in the system.
How interchangeable are compressors. Do I need another Delphi 1135463 or will any off a 2.0 HDi fit?
