    Leaking compressor

    Hi, hoping somebody can help me.. I can see that my AC compressor on my passat b5.5 has been leaking refrigerant from the point shown in the photos, it is a brass part and has a circlip..the system is completely empty now so I was wondering if anyone can tell me what this is and if it can be removed and o-rings replaced or not.

    Many thanks

    That needs a new compressor, the insert is plated steel and the ally body of the compressor has corroded. It looks like a Delphi unit and I replace these with genuine Denso units which as superior.

    One more thing.. Will I need to fill the compressor with oil prior to fitting it or should it come pre filled?

    I replaced the compressor and followed the procedure of first draining the oil from the old compressor and measuring the amount, then drained the oil from the new compressor and refilled with the same amount of oil that was in the old compressor, this was about 50%. The system was then vacuumed and filled with refrigerant and now the air con is working perfectly.
    Thanks for your help
