A question about car batteries…

The traction control and brake indicators on my instrument cluster have turned on, on my 05 BMW 330. Using INPA, I have a few codes that I’m working on, one of which is electrical (overcharging?).

I checked my 51R battery with the engine off and I got 13.17v and with it running at idle, I get 14.00.

How is it my battery is registering 13.17v? Shouldn’t it be 12.6 with no load and the engine off?

Edit: how is it my ABS – DSC system voltage is seeing higher than 18v If I’m seeing 14v at the battery at idle?

Codes below:
5DF7 ABS-DSC: System voltage > 18 volts dsc_mk60 Stability system MK60

5D97 ABS-DSC: DSC sensor, voltage supply dsc_mk60 Stability system MK60

5E43 ABS-DSC: Steering angle sensor, internal dsc_mk60 Stability system MK60

5E24 ABS-DSC: Pressure sensor dsc_mk60 Stability system MK60
