First, try turning off the transfer phone book option on the Pearl. If the phone starts working again, then you will know that the problem is related to something in the phonebook on the Pearl.

On mine (and others), my Pearl will not stay connected if I have any groups setup. This is unfortunate, but I suspect it is a defect in the Pearl that kills the connection to the BMW Bluetooth module by sending incorrect data.

The other thing that caused my Pearl problems is when I had non-numeric data in the phone number fields, such as alphabetic characters, "ENTER" characters, etc.
