I have a 2004 (E60) 530d with Active Steering. Whilst there are real benefits to this system, I find the car can 'wander' at slower speeds (0-40mph) when the car encounters uneven road surfaces. For example, if the car finds a ridge in the road the steering wheel will turn quite sharply of its own accord, far more pronounced than on the E39 I had previously.
Above 50mph the steering really tightens up and the problem reduces, but the issue remains - making driving in a straight line an effort! All the reviews I have read of BMW's Active Steering all seem to praise the good points of this system, but with no mention of this quite obvious (and some times alarming) handling issues!
On an even surface it handles fantastically well.
Does anyone else have any handling issues? Any tips for correcting these issues?
