Have you solved the issue?
I havent visited forum for a while, but i have answers.
The easiest way to apply parking brake recall campaign, dealer will change the required parts and recalibrate it.
If you dont want to do so - EPB errors cant be read with cheap OBD scanners, as these scan engine errors. you need SSM (original or clone), Launch or similar diagnostics tool which read errors from other car units ans also have recalibration functionality.
You can read the errors, but most probably you just need to recalibrate clutch pedal first and only after - recalibrate ECB.
I had same issue with ecb after rear brake rotors replacement - ecb had same behavior. But luckily i own Ssm
