2001 Allroad - fuse #5 has no effect on warning lights - why?

[Bart Oleksy]

Just for kicks, while awaiting the resolution of my airbag warning light 
(and VAG-COM error 65535), I tried pulling out fuse #5, which according 
to the manual is supposed to control the warning lights including the 
airbag warning light.

Yet with fuse #5 pulled, the airbag warning light still comes on... 
Would I need to do something to make it 'take effect', like unplugging 
the battery or something?

Thanks.
