[328Delta]

Greetings from hopefully not your new problem child. Any help is appreciated. 2010 335D no crank no start. Just single click, or 5ish fast off rythm clicks. Sometimes.

Backstory:
Was rolling car backwards while eng. Off and in reverse, anti theft alarm sounded.
From there: 2 failed starts, 1 successful, 20+ failed. No check engine light or codes.

Attempted fix:
Batt. Disconnect, grounded against +\-
Waited 30 mins

Checked batt. 12.5 volts
