Have a bit of an odd issue going on once sub-zero temps hit. So whenever I start up my car these days I've lost my date/time and also trip miles. All of my audio settings and service intervals are still there. What is going on here? My battery voltage should be good as my dash cams are still working and that has a LV disconect of 11.6V. 2008 BMW 328xi E90
Your battery is low on charge and the car keeps tripping the 30gf relay to save power to start the vehicle. 11.6v is a battery very low. 12v reading on a battery is basically dead a fully charged battery will have 12.6v. I recommend if the battery is aged to have it replaced and registered.
