Sounds like you have a loose connection somewhere. Maybe back at the battery or i've seen the positive battery cable that goes from the B+ jump under the hood, over the engine and down the to starter. Make sure that's good and tight.

Certainly a power issue, the windshield wipers going on without turning them on is an indication of low voltage. Could be the alternator and the battery ran down - have it tested. It could also be a loose connection - prime suspect would be the wire behind the fusebox if your care was in the recall range for that cable and has not been replaced 2007-2011 https://blog.bavauto.com/13516/bmw-r...e89-13v044000/

Sounds like symptoms of bad voltage regulator. Use voltmeter to check output voltage while engine is idling to confirm, should be around 14.2 volts. There is a positive terminal under the hood that is easy to check to ground.
