Background information relating to the B+ battery connector recall.
Following an ongoing quality analysis at BMW, it has been determined that the plug-in contact of the positive battery cable on the front power distribution box can become damaged. This is caused by vehicle vibrations and frictional corrosion, together with a high load current. As a result, damage to the plug-in contact can impair the power supply of the vehicle.
Until the recall repairs have been performed, it is important to note the early symptoms detailed below:
The vehicle central locking system fails sporadically
It is no longer possible to start the engine
Flickering of the instrument panel
Jerking or momentary power loss from the engine whilst driving
If the above early symptoms are ignored, a loss of electrical power and cutting out of the engine may occur.

Background information relating to the to the blower regulator connection recall.
The blower-regulator controls the blower-motor’s fan speed within the heating and air conditioning system. BMW have discovered that irregularities in the connection together with the movement of the tin-coated connector at the end of the wiring harness could lead to frictional corrosion. This, in combination with very high current flow may lead to a temperature increase.
For vehicles affected, the blower-regulator wiring harness will need to be inspected and a new part will be installed.
