The Golf IV ('98 - '03) had a Pitch Circle Diameter (PCD, diameter of the virtual circle on which the stud holes are drilled) of 100 mm. The Bay Kombi (and later Transporters) needs a 112 mm. PCD. The Golf V ('03 - ??), however, has a 112 mm. PCD and usually has offsets in the range of 35-42 mm; the standard for the Bay Kombi is 39. The centre bore (size of the hole in the centre of the wheel, important for correct seating) is 57.1 mm in all cases.
Summary; if it's from a Golf IV, no. If it's from a Golf V, maybe (the numbers look right, I just don't know of any documented examples).
