I have this light on the dash but the brake lights work.

What can I do ?


EDIT
I need to excuse about this.
I assumed it was like when I saw it a few days ago.
Just went to the car minutes ago and the all centre light is burnt.
Not a single led lights up.
So, Sorry for your time.
I need to buy a new light or at least check if is just bad wiring.


My bad :-(

Audi's have been known to pick up the fault before the lamps pop....
