Went to my mates today guys, who's bro is a vag mechanic, as i was going on the 20 mile run i noticed my left window wiper on the leon was squeeling a bit and looked to be struggling to operate?? It had been icy in the morning as i had washed the car on fri night and left it to sit. Spoke to my pal's bro and he had a look, sprayed a bit of WD-40 on the bolt and tried to ease it. The bolt was solid!!! He checked the drivers side which was absolutly fine! Passenger side was unbearably solid but as it was starting to get damp and dirty with the salt still on the road, i wanted to get it working, he sprayed a bit more wd, and was still squeeling, so he went to try and slacken it and snap!! the bolt had sheared off perfectly in the nut! Had to take wiper off thankfully my drivers side is perfect, but it is meaning a new wiper motor!!! Raging!!! Just wondering if this has happened to anyone else?
