I have a 2009 328i n51 and recently I was driving and the check engine light came on and the AC stopped working can seemed to run fine then a day later I hopped in and noticed that also the fuel gauge was no longer working and was reading that it was empty fuel. I used the cluster features to see that both fuel sensors weren't reading anything the codes for the car come up as fuel level sensor a circuit high voltage. Same with sensor B, same exact code for thermostat circuit high voltage.

P2068
P0463
P0599

It shows these codes twice so a total of 6 codes pop


Battery ready 14v while on 12.5-13 while off
The blow motor regulator is hot to the touch (I don't know if this is normal)

I have 96,000 miles on the car anyone have any idea what can go out to make these malfunction?

Did you have the blower motor connector recall done?
N51's are noted to have fuel tank problems but it is mostly with
the internal fuel lines self disconnecting.
It's not a good idea to run close to empty as the fuel in the tank helps
with fuel pump cooling and the bottom of the tank has the dirtiest fuel.
