For a BWA, separate the brake vacuum pump from the high-pressure fuel-pump follower when asking for part numbers. In the earlier Vacuum Pump topic, 06D109309C answers the follower question, while the later seal-kit discussion concerns the vacuum pump. A seal kit and a complete pump also need separate entries on a parts list.
CarParts247, which I help with, lists
Pierburg 7.24807.20.0 against vacuum-pump references including 06D145100H, with Golf V 2.0 GTI among its applications. Compare the complete fitted reference and connections before selecting it. The listing is for the vacuum pump; it does not establish that a leak needs the complete unit or that the follower is included.
