Sandres

hi everybody, i have a question about my pdc. Sometimes my pdc works like it would normally and the pdc button doesnt flash green light which means its normal. I have also checked all the pdc sensors and they beeb a ordinary noise. but at the other hand they begun to go crazy and doesent work for no reason, and it automatically reports a pdc failure message on the idrive. plus the pdc button inside the control pannel flashes green light?
i have connected my obd tester into my bmw, and it reports me the failures in the picture bellow. Does anybody have the porblem before or have known to the problem ??
