Hi Clemens.. the problem with our wipers was the mechanical wiper mechanism itself, first they would not park, then they parked in any position, then they tried to wipe the bonnet!. So the factory fitted a new mechanism, this second replacement mechanism semi auto destructed some months later, I was told part of it had seized. The last factory fix was another new complete mechanism which does seem to be better made, the axle shaft and spline area appears a higher quality finish, so maybe made by another manufacturer?? ( I dont know this for sure, but it is different to the first two in that area ). I am trying to find the embedded BBcode in the TM image library photo of the mechanism, but no luck so far. So I have put out a question on the forum about this, as soon as I can find this I will post the photo.. This is of the wiper mechanism less its motor..
When our second mechanism auto destructed the complete external arm, axle shaft and its exterior clamp came loose, thats why I was able to see how the axle came through the body work and also see the sealant applied in that area and the gasket on the axle clamp..
