To replace the light bulb for illuminating the digital clock, you need to
first remove the instrument panel cover (pull toward the driver seat from
the windshield-side of the panel - finger holes on either end), then the
instrument panel itself (4 screws).

The bulb is located on the small ciruit board for the clock. It is a
twist-to-remove blub. Part #2722MF8 and is 12v 2 watt. Your best bet to
find replacement bulbs is a VW dealer, I've not found them anywhere else.
Buy a few spares, these bulbs are used in various other dashboard-related
locations.
