Noticed battery was not holding a charge so had another battery charged. Swooped batteries, go to turn car on to code battery and nothing. No crank no lights nothing. Tried to jump car to see if that would get it to start and no. So switched batteries back out, tried to start and same thing. Try and jump that battery. Nothing. Had to have car towed home. Next day go hey a brand new battery put in car and now still same thing. I honestly don’t know what it could be. From what I’m reading - fuses, alternator, starter, anti theft system, key…

if anyone has experience this and knows what might be causing this I would great appreciate help.

 

Let's start with year and model? Have you done anything else before this started. Have you did anything other than change the battery? Have you check the MPM is the tire well?

 

2008 535xi, no nothing was done except changing the battery. I have not checked the MPM will go check now
