Hay guys,
My fastback have exactly the same problem described, I tool it back to the dealer not long after newly purchased from Melbourne dealer, first time they say it could be the whole steering column needs replace, had to wait for dealer to schedule me back, took it back and they didn't change anything or maybe fiddling with some parts, drove out the dealer seems fine, then same issue happens again after a day or two, took it back and they've replace a bigger washer "as been told" after few days ....again same issue reappears. so 3 attempts and the dealer still could not fix the problem. I'm not sure they are trying to take a short cut trying to fix the problem or they are just not sure how to fix it.. sighhhh,,
