If I also bought an Audi V8 3.6 L BJ 89 today, my winter car will be

But I've got two questions:
When I lock my vehicle, a short warning signal of the horn - windows, doors, hood and trunk are closed, but when they open and close, they also unlock properly. Is the signal normal or should it point to a mistake?
And my elek. Seat adjustment doesn't work, so far it has only been tested with ignition, did not want to start the car unnecessarily - due to rather weak battery.
Does this work with running engine or have I already found the first defect?^^
Thanks already and greeting
Lex
