hello good people of this forum, having a problems with low beam headlight turning on and off while driving, they come back on after about a min or two, high beams no problem at all, fog light will shut off sometimes also, most of the time fog lights will work after low beams have shut themselves off. on to number 2. I have no led readout on the dash at all, car starts up fine, but no warning lights or gas and temp gauge working. only Speedo and rpm's. on to number 3. replaced the battery with a new one, because was told by BMW dealer my battery was not holding a charge and that's why my obc was switching from English to German back and forth, so now my obc has defaulted to pppp.
and still have all the above problems still. any ideals. been told that this may all be a grounding problem causing all of this, been told to disconnect and reconnect the obc. am I missing anything here except a gun to shot this thing with

thanks for any help and ideals good people.
