Vw passat b6 parking brake issue

Hello. I have a 2009 VW Passat B6 Highline. I have it for a while now. But recently the parking brake fault light came on when i tried to release it. I turned the ignition off and then back on and then it released it. But now it does it almost every time I try to release it. I know it a common issue for these models but maybe u guys know how to fix it.
Thank u!

Fault code read first, it may just be the push button which is called “control head” in a fault code.
