During the era of BMW ownership and subsequent platform sharing, Range Rover used the identical AMK compressor pump. Land Rover OEM listings charge £450+, whereas buying the unbranded AMK unit or the BMW-badged equivalent drops it to £180–£220.
SO WHAT'S THE CATCH?
Check compressor version, control compatibility and any required software.
