Default Keyless Entry Issues

Hi all,

I have an 2015 Audi A4 3.0 TDI, bought second-hand, owned for about 3-4 weeks.
Today I've noticed the door not locking / unlocking with the handle sensors. Immediately, I tried all other 3 doors and none of them work.
Yesterday the keyless entry system worked just fine.
On top of all these, I've noticed that the key fob's red led lights up when I touch the door handle, so the sensors are working and the fob is receiving the signal.
Anyone else had this happen? Any advice on what to do?

Scan for codes, see what the problem is as the car computer sees it.
