Some info regarding PA and ACC. Till MY 2021 there were 2 types of hidraulic units. "weaker" and "more powerfull". They located on the left side, close to front left wiper. To check, wich one You have-open the cover to access brake fluide, then put Your phone on stick (or, if You have long hand) insert it there with camera on, and try to record video on unit's pump side. If You see 772 - old "weak" unit, if You see 774 - You good to go with acc activation and it will work smoothly.
