    Has anybody else had this before?

    My rear bleed nipple appears to be leaking brake fluid, im having to top of every week or so...

    Its not loose but fluid is seaping out the top.

    Easy job to change but from what i've read bleeding the brakes is not as straightforward as other cars....

    I wonder it the nipple has been over tightened or knocked?

    If replacing just the one nipple, then you would get away with only bleeding that corner. You need to use a pressure bleeder (push or suck) not a traditional pumping pedal method. Pressure should not exceed 1bar.
    You won't need to bother with vag-com abs cycling if you keep the reservoir topped up.

    It was serviced in January but started leaking about 6 weeks ago, a bit strange but these things happen :think:

    Where would I get a pressure bleeder from?

    I have the gunson ezibleed setup. You can get them from Halfords for about £20. They work pretty well using a spare tyre as the pressure source (deflated to 1bar). Also grab a large syringe or turkey baster to remove excess fluid from the reservoir when you are done.
