If I change the battery in my BMW does it need to be reprogrammed?

I have a 2012 BMW 520d. The battery is the original and would not start the car after not being used for two weeks. It's fine when I use the car regularly. Is this a job I can do myself, or does the battery...

Is my power steering failure down to a low battery?

My power steering has failed.The power steering warning light has not come on but the battery warning light is on now constantly. Is the power steering failure due to low battery power?

Why am I getting a battery charge failure warning light in my Rover 75?

I'm having battery charge problems with my Rover 75 CDTi. I get dashboard warnings that all go away when you charge the battery, but return twenty miles afterwards.
