I think mine has fell apart inside itself as it sounds horrible.

Looking at replacement compressors on eBay the cost varies quite a lot and Im wondering if they all fit.

http://www.ebay.co.uk/itm/Range-Rover-L322...4aa8199a0a £483.90

http://www.ebay.co.uk/itm/Land-Rover-Range...4626f5603b £299.94

http://www.ebay.co.uk/itm/DENSO-A-C-Air-Co...4d23741c65 £311.94

http://www.ebay.co.uk/itm/AIR-CON-COMPRESS...3a82ca9e5c £150.00

Ive recently become poor so £500 for a part I could maybe get for £150 really matters
