BMW 6 Series - Tech Talk E24,E63,E64,F12,F13
This light came on this morning. Came in and off for a whole, then stayed on. Belt still on and turning
Testing when I got home, voltage is the same whether engine is running or not (11.5 volts). I have put it on charge to give me a full battery to get to the garage.
Any ideas, or is it...
