    I have a 330Ci vert that I don't use a lot, battery is dead and I am deciding between buying a normal group 94 battery or an AGM. From what I researched, I didn't find enough information about AGM batteries with E46 verts. I read that they have an special "anti-vibration" setup; which got me...

    Hello guys! A few months ago I had a completely dead battery around 1V. It was 70Ah, so the new one I got was 74Ah if that makes a difference. After that, I also changed the interior fan control because that was actually draining my battery in the first place. All was fine until I noticed that...

    Hey guys, I was driving home in my 05 325i and my battery light started flashing. At the end of each flash my lights brightened up and when I parked, my car dropped revs in sync with the flashes of my battery light. Anyone have experience or any answers? Thanks

    Just bought a new battery because the old one was clearly dead, but I noticed that my nav unit in the trunk just randomly turns on even if the car isn't turning on. Can the nav unit be a source of power drain?

    Hey all, I recently had to replace my E46 M3's battery and I'm having some issues I'm hoping I could get some advice on. It all started when I couldn't start my car a few weeks ago -- the battery was probably 7 years old so it was time. It was a BMW battery, and I replaced it with a Duralast...

    I have a 2003 325i with 156k miles on it. A few months ago I started having electronic issues with the car not starting in the morning and the radio shutting off. I noticed the battery was quite old so I replaced it with a OEM battery from a E90 dated 11/17. The car daily drove for a few more...

    Noob here, trying to sort out the little issues with my 02 convertible. The air bag light is on. When I first got the car a few weeks ago I took it to the dealership to get the air bag recall work done. They said the light was on because of corrosion on the battery terminals. The negative...
