some errors with BMW scanner

[Osobuque1]

Hello, a few days ago reading with the BMW scanner was giving me the following error in Red.

BF [191] Internal Fault EEPROM checksum 1 coding incorrect / incomplete.
the fact is that after a few days without start the car, today I decided to go and fiddle again to see if I could remove the error.

The case is that after activating some options in IKE to give it to write, the error has been disabled.
But when I have gone to start the car, the car won't start, and the interior lights start to flash.
I try to do it several times, and nothing, it is the last ones when hitting the ignition position 2 before starting it, all lights on the instrument panel go out. I pass the BMW scanner again and it gives me the following errors in the ZKE module:
0D [013] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Driver´s door
0E [014] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Passenger door
0F [015] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Driver´s side b ....
10 [013] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Passenger side b ....

Shadow:
90 [144] Battery Voltage: Open circuit.

and in the EWS module I get red the error: 2A [042] Error number 2A

I have checked the battery and it is in 11.5v.
what could be the fault? Is the battery voltage low, or could it be something from the checksum that is both

Today I was able to clamp the car off,
But now it keeps giving me a few more glitches. How could I remove them? I give him to erase failures and he does not erase all of them.

These are the ones that still come out red.
EWS module:
2A [042] Error number 2A
IKE module:
BF [191] Internal Fault, EEPROM checksum 1, coding incorrect / incomplete
ZKE module:
0D [013] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Driver´s door
0E [014] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Passenger door
0F [015] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Driver´s side b ....
10 [013] Power window: Open circuit Jam Protectionstrip or scaling / Error EKS electronic Passenger side b ....
LEW Module:
09 [009] No CAM message (ASC)
I also got yellow in the VTG module:
5504 [21956] No CAM message- DCS1

I have eliminated some errors.
I have driven a few meters with the car, and the lights on the 4x4 display and some others have been removed.
I believe that the errors of the LEW Module have been eliminated.
The errors of the ZKE Module: have been eliminated after lowering and raising windows, and giving it to erase faults.
I still have the error in red
EWS module:
2A [042] Error number 2A
IKE module:
BF [191] Internal Fault, EEPROM checksum 1, coding incorrect / incomplete

And in yellow
VTG module:
5504 [21956] No CAM message- DCS1
LCM module
2A [042] HVA potentiometer faulty
2B [043] Dimmer potentiometer faulty
3E [062] Rear fog faulty
41 [065] Low bean right

How could I eliminate the error of the EWS module: 2A [042] Error number 2A?
