2015 VW golf SV passenger side rear brake light fauly

[blahzilla]

Hi all, just looking for some directions on what I can try next, grateful for help.

My passenger brake doesn't come on when I depress the brake, and the yellow warning light shows to confirm it.

I've changed the bulb, difference.

The indicator light comes on so I assume that means the cluster is ok?

 

Is there a fuse or some trouble shooting I could take to try and narrow the problem down?

Thank you,
