My 2003 330xi is doing the same thing. Noise over bumps and up and down play in steering wheel. Before I spend 150 on a steering coupler id like to make sure its that and not the column bearings or something to that nature. Also on cold idle my whole steering wheel shakes and rattles. That's how bad mine is at 136,000 miles
