135i not working properly

[prass]

Hi! I’m having problems with my 135i 2008 n54. Out of nowhere numerous sensors just stopped working (all at the same time one day when I started the car) and the fan is going on 100% with rough idle and limp mode. The problem came before and just one day it disappeared and now it’s back. It happend 3 weeks ago and just restarting the car fixed it but that doesn’t work now. The car won’t upshift more then 3rd. I’m sending a image with the codes I get if someone knows how to fix it or got any ideas on what I should do.

I'd start by checking your battery, these things start getting schizophrenic when the battery is low.

The battery was last charged for like 15 hours yesterday. You think I should charge it more?

Can it be a problem with the f11 fuse maybe?

Was it recharged because it was already found to be dead? When was that screen shot taken relative to your recharging? I see it shows 11.73 volts, which seems too low.

As far as charging goes, maybe somebody else can chime in as I don't know if that messes with the vehicle's smart charging system (it charges based on battery type and age, and requires resetting when replacing a battery, but I don't know if anything should be done if manually recharging).

Found the fix. Fuse f11 wasnt fully pushed in. After pushing it in the car is back to normal

I wonder how this happened. Were you messing with the fuses at one point?
