2002 S8: troubleshooting Central Locking system code

Hi, Auto-Scan indicates the following faults. Locks still work, and I disassembled the pump to inspect for common breakage of interals, but it looks good. So Im guessing theres just a vacuum leak in a hidden line somewhere?
Thanks,

I suppose it could also at one of the actuators. Check if one is slower or more sluggish than the rest.

The other fault codes are common in those modules of that vintage. Just clear them.
