does anyone know how to remove the rear windscreen wiper on a mk4

yeh u flip the plastic housing on the bottom of the wiper, undo the bolt (i think its 23mm, could be totally wrong.) use wd40 and some pliers to slide the black sleeve off and undo the second bolt. the wiper arm should come off, leaving a penis shape sticking out the back of your car. now open the boot and remove the plastic trim, unbolt the big metal thing in the middle which is the wiper motor. take it out and put it in the shed. block the black pipe for your washer fluid with a screw and blu-tac or fold it back and cable-tie it so no fluid gets through. you should be left with a gaping hole. at this point you realise you should have bought a 28mm grommet from halfords beforehand. you need to glue or seal the black rectangular piece onto the windscreen and insert the grommet. job done in around 10mins (depending on how far halfords is).
