First off, since the car has 109k miles on it any CPO coverage would be expired based on mileage. Seeing as this is a known issue, it may be worth a call to BMWNA to attempt for some goodwill assistance.
Make sure the subframe is checked for contact and the reason for the contact is determined and rectified, otherwise you could be in the same situation shortly after having the repairs done.

The models listed above utilize a single serpentine drive belt for the power steering pump, alternator, and air conditioner compressor. During normal driving, the front engine mounts allow the engine to move slightly on the front axle carrier. However, under extreme conditions, such as driving at high rates of speed over curbs or speed bumps, the engine movement can result in the serpentine belt or power steering pump pulley contacting the front engine carrier. If this occurs, the belt and/or pump pulley could be damaged.
PROCEDURE
When diagnosing a complaint related to a broken drive belt or a drive belt which has come off the pulleys, it is important to carefully examine the power steering pump pulley for any signs of damage.
If there is no damage to the pulley, continue with normal troubleshooting.
If the pulley is chipped or cracked, then the pulley and the belt must be replaced.
In cases where the pulley has been damaged, the front axle carrier should be examined for any signs of contact in the area below the power steering pump pulley.
If the axle carrier has any sign of contact, then the carrier must be replaced. For E90, E92, and E93 vehicles produced up to 3/19/07 which require replacement of the front axle carrier, the left side engine support (P/N 22 11 6 760 317) must also be installed.
