vw can give you a temp 7 digit pin (valid only for certain day)
did some more checking into coding mk4 clocks, pretty sure vcds can't activate the things you want.
would need to have vag dash for that, don't have that. (only got vcds lite full version, soon to be upgraded to full vcds since i swapped my mk3 for a mk7, but even that can't do some stuff...)
