Current draw tests done twice by Dealer and BMW specialist & no problem found.If we don't plug in a charger it will drain within 1 to 3 days. Battery replaced several times. Main battery cable replaced. Secondary coolant pump replaced. Alternator replaced twice. Driver seat relay replaced. This has now been going on for over 2 years. Dashboard odometer lost pixels, cant read it or the outside temp display. Don't know if it can be related. Also get inaccurate warnings from dashboard like check engine oil, brake linings coolant level, etc. Thanks for your help.

EnthusiastDoes your vehicle have factory navigation? I've seen mysterious battery drainage problems that lead back to the navigation module in the luggage compartment. You can unplug it and see how it affects your battery issues. Good luck.
