Never change a running system – I should have noticed it. After I had made the mistake during the last inspection because of draught and noise to let the front doors “adjust” go now despite rework not satisfactory anymore. i.e. you have to draw or throw with some traction force. Try makes smart, therefore I want to give myself with peace and time. Does anyone possibly know which screws to use? I find 3 starting points, which I am interested in The cover cap in the 3rd picture has been gone since the last injection, so I have the assumption that the fitters worked there.
