Hello, iv just fitted cruise control to my MK5 2.0 TDI 140 GT 2006. it was the kind that replaces the original indicator stalk and the cc is built into the new one

my car has,
midline display with on board computer
1K0-953-549-AF control module
1K0-959-653-C Slip ring
each of with i have read are compatible with the retrofit.
i followed the instructions to install the stalk which was easy. no problems. then i got the the part with the one single wire that is included with the kit...it says disconnect the black plug from the module at the bottom of the steering column, check pin 13, if there is a wire present you will not have to fit the supplied wire. on my car pin 13 has a black wire with white tracer so according to the guide all should be good.
i put everything back together, connected the battery and recoded my steering wheel with vagcom from 0000012 to 0000042

everything coded fine. but when i flick the switch to turn on cc it doesnt work. i dont get the cc dash light, nothing!
does anyone have any ideas on why it isnt working? have i coded it wrong, or does the supplied cable need fitting and if so where would i put it? do i remove the wire that is in pin 13?
