    Weird lighting issue

    Canadian 2011 128i.

    Got the light warning on the cluster. Here is the behavior:

    Light Tail lights Side Markers Front Markers Inner headlights Outer Headlights Pass Angel Driver Angel
    Park on OUT on -- -- on OUT
    Low on OUT on -- on on on
    High on OUT on OUT high on OUT


    Most confused by the drivers angel eyes. As far as I know everything was fine "yesterday" and no warnings were being thrown.

    Inner headlights are always out.

    Very strange set of failures to happen all at once, any ideas?!

    Check the voltage at the jumper post located under the red plastic cover under the hood. Use the engine as the ground. Check it and report back you findings when the:
    - car is off (hood open, obviously)
    - accessories on but engine off
    - engine idling - engine revving at 2000rpm.

    Your battery is shot! A fully charged battery will read about 12.6VDC. Your alternator is really pumping out the juice in an attempt to charge the battery. Don’t forget to register the new battery. Our cars have an intelligent charging system whereby they use a different charging profile fir new batteries redid old batteries.

    You may be able to do so with Carly. BimmerCode doesn’t have that capability as far as I know. Contact the people at BimmerCode to find out.
