I let my 2011 328i sit for 2 months while I was out of town and when I came back it wouldn't start. The navigation screen said it didn't have the voltage to start and it was about time to replace the battery so I bought a new one. Now I get an error saying, "Ignition switched on" in the navigation system. No codes in my code reader. I've attached pictures. Bad starter? Hoping someone has seen this before.

If the starter is going bad and is cranking very slowly, then it might be the starter.
If it cranks like normal, it’s something else.

Could be a good idea to spray some starting fluid on the intake to see if it starts like that. Maybe your fuel pump crapped out after sitting. Can also go under the fuel tank and give both sides a few good bumps to maybe kick the pump on.

I got it running. Thank you everyone. Here's the solution for anyone that has a simular issue:
I had my wife spray valvoline extra strength starting fluid in my intake. I forgot to tell her to only spray for 2-3 seconds so it started turning over but stalled. It sounded even worse after that. I then took out my spark plugs and wiped all the crud off of them from the burnt starting fluid with a shop towel. I then rotated all of my plugs and coils. After I put everything back together and tried to start the car it sounded like it was trying to turn over but wasn't quite able to. This happened twice. Then I let it sit for maybe 2 minutes and tried to start it again and it worked. Fuel pump replacement is now added to the to-do list. I'll probably do that when I replace my valve cover gasket.
Moral of the story: Text my wife once a week to start my car when I'm gone and I need to keep better maintenance of it.

Awesome, glad you found what the issue is now

My 2011 328i had been sitting for a few months. Battery was old and weak so I got a new one. The car turns over, but sounds like it's not getting fuel. Hmmm...here we go!
