    Been trying to fix leak in the back foot well of the A4 have nailed it down to the trim that covers the windscreen has slightly lifted with been taken off so many times.......and i have been told that the pollen filter housing can sometimes let water in (loses it seal )

    Any body here have the same problem?

    Cheers

    Right thought i would take a few pics of job

    REMOVAL OF POLLEN FILTER HOUSING AND RESEALING

    Took the cover off the windscreen three plastic screw along the top which just need a quater turn to come off there is a one 8mm head bolt that holds it down on the back in resess of the cover
    Plastic runner that feeds water either side of the pollen filter just slides out on runner were it is held in with sprung loaded clips

    Slip pollen filter out and you have Three 10mm head nuts to come off ,one inside housing and two which are on the side of the wing(note 1/4 inch drive sockets easier to get in)should lift up on side of one nut and slide round and you sould have this
