Found out that since my wagon, similarly like b6 has epb (electronic parking brake) it needs vcds to retrace the motor that will allow you to push the piston in.
On that case the question is: where and how do I put parking brake into service mode??
I've seen people disconnecting the motor and externally connecting 12V supply to retrace it that way, or someone removed the engine completely, but I'm not fancy doing the tricks on tricky car, I rather stick to straight recommended way.
Any help much appreciated
