hi, I am new to the forum. I've just bought my first BMW I had an AUDI QUATTTRO previously. I've only had the bm. 2wks which is the X3 3.0 sport auto. 2006. sometimes whilst driving the stearring starts to wobble for no reason breaking is not effected once the car has stopped you can set of again and it may not come on again for another day or so. all the tyres are the same preasure + tread will try balancing and 4 wheel tracking. I would be greatfull for more info before i start trying the expensive options. regards,Daryl. P.S. the car has done 94k.
