Rear brake job replace calipers

[Pecia]

Hi all,

2018 2.0 awd

Calipers needed be replaced
Did the job, released the rear emergency brake.

All went well until bleeding left driver side.

Got the crazy error C0561 symptom byte 43, a service park brake message on the DIC .

Right side emergency brake works fine, left side does not.

Regular brakes work great.

Stupid design imho.

I’m sure I did some thing wrong.

I re engaged thr parking brake. Left side gives a message that malfunction with motor. We took motor got e brake off and power it on the bench and it goes in and out fine.

Any help much appreciated.

Thanks
