fault codes

[AdamE53]

So, I have a ew fault codes from Bimmer Tool that I cant decipher:

ZKE central body electronics
A7(167)
A6(166)
59(89) driver door lock circuit interrupted?

Im having central locking issues so i'm most interested in deciphering these.
I recently rebuilt the drivers lock with a kit and it was working again but has since stopped locking electronically, only manually locks the drivers door (central button not working either)

KOMBI instrument cluster
BC(188)
BD(189)

DSC
20(32) front right speed sensor?
6C(108) brake fluid level switch? topped it off recently

Unfortunately Bimmer Tools doesnt have all descriptions and they can be hard to find online. Any help would be appreciated.
