Hi i have a z4 3.0 on a 2003 with an intermitent steering fault. The steering works perfectly then all of a sudden doesnt work at all. Some days will not even work when starting the car. It does not have the notchy feeling wich alot of people have had problems with, when it works it works perfect.
I have read alot of things about this and it seems very common, but nobody seems to actually explain how they solved it. It does not get affected by the temperature, it could happen or work fine in hot weather or freezing cold weather.
i real realy could do with some help on this from someone who has resolved the problem or has a good idea of how to.
