N55 No crank no start (help)

[bhr_beemer]

Hey everyone

Yesterday I jacked up the front of the car to change the oil on my 135i N55 2011. 135,000 KM

After filling the car with oil I pushed the button to start it and I wouldn't start.

I could hear the starter clicking but it's not spinning.

I connected the scan tool and here's the codes I got:
A0B4 - Absent - Car Access System (CAS): Engine start, starter operation
A0C1 - present - Car Access System (CAS): output, terminal 50

I checked the live data specifically terminal 50e (is it the one mentioned in the fault?) and saw it changes from 0 to 10.76volts while pressing the start button.

I am assuming that the starter is getting power but maybe it gave out? how do I make sure? how do I test it?

The battery is 1 year old and it reads 12.11volts on the scan tool.

Appreciate your help in troubleshooting this issue.

Thanks
