    2003 Polo A/C Compressor

    Good afternoon, all!
    The A/C compressor on my 1.2 Polo has become increasingly noisy, it is making a grating sound that increases in pitch as the engine speeds up. I usually run the A/C continuously, but now put it on for a short period only on each journey to ensure that the seals don't dry out. Can these units be serviced, or has it reached the end of it's useful life? The car has covered 59,500 miles.
    Any comments greatly appreciated.
    Regards

    When did your refrigerant level last get checked/topped up?

    I ask because both my Polo and the missus's Fabia had noisy compressors earlier in the year (like you describe), and both were 'cured' by re-gassing. So far, touch-wood, neither has got noisy again. Both cars on 135K+.

    Your compressor operates continuously on a variable displacement system by the way, so somewhere around 2-4% of the refrigerant is pumped round regardless of whether you switch the system on or not. So no need to do anything to keep seals lubed.

    Good morning and thanks for your prompt response. The refrigerant level has never been checked during my ownership - I'll have this done asap and let you know the outcome.

    Good afternoon, I've had the system re-gassed and that has solved the noisy compressor problem! Many thanks again for your post.

    I'm surprized its lasted this long without a re-gas. When an AC system is re-gassed. They add new oil, refrigerant and dye in case there is a leak, which lubricates the compressor as there is no separate oil feed or dipstick.
