Finally got round to changing my rear wiper motor, what a mission that turned out to be, not so much changing the actual motor but getting the plastic trim back on I expect most people on this forum have come across the sprung metal clips that hold the main part of it to the tailgate it would appear that these deform rather easily when the trim is removed and require the worlds supply of manipulating with bull nosed pliers to correct the shape for refitting.

Found it easier to sit in the boot and pull the tailgate down until almost shut then slide the top part of the trim into position then push the clipped part into place, I lost a couple of the spring fixings and was wondering how much Audi were likely to rob me for another set, deep joy I found them on eBay three quid for ten plenty of spare clips but I suspect the clips are of a one use design.

So glad you got this sorted Steve. Ironically it's often the trim that causes the most headaches. Often doesn't want to go back on. 

Cheers

Steve
