On my new Blackwing (which I pick up tomorrow - probably my last post here) the consensus on the forums is that the OnStar module can be disconnected from the antenna easily with no ill effects. However, it's not clear how long the module retains data it receives, which might be downloaded when the dealer hooks the car up to GM before doing any service. The cable from the car can also be disconnected or the entire module can be removed (it's in the trunk) and apparently the car still works fine. Since I don't want or need any service or snooping from OnStar, I plan to remove the module.

It might be worth trying to find out whether the snooping hardware in the 2-series is accessible and whether it can be disabled or removed. If I were keeping the 240i that's what I would be looking into.
