Ibiza TDI 130, how much of a pain was it to fit the rear blade? There was a thread about this a few weeks ago (can't remember who) but they said it was an easy fit, just required a bit of filing.....?
It may have been my thread
I've just finished putting the aero rear wiper on, today! Basically, you need to ensure that you don't fix the arm on too tightly, otherwise it will touch the screen. You then need file some of the new cap off to make it fit, thanks to mja_fin for the following advise
Firstly, if you look at the back-inside-side of the cap (the side that points to the opposite direction of the wiper), you'll notice that there is some protruding plastic - you'll have to clip off some 0.3-0.5cm of it, otherwise the cap will not clip into place, as it will be hitting the round rubber part in the rear window (I think it's a seal... you'll notice it when taking off the old cap). The second modification is easier. After fitting the new wiper and cap if you try swinging the wiper, you'll see that when it reaches the far end, the plastic cap will be touching the window (and the cap will probably pop back up). So you'll need to take the cap off and use some sand paper to take a bit off of the cap. I just held the cap flat on the sand paper and took off about 0.2cm all the way round. The cap will then clip into place, hope this helps!
