I have a 2005 Fabia VRS 1.9 tdi. It's on double click unlocking at the moment, have to push the button twice to unlock all doors and boot etc. Have looked on VAS machine in adaptions in convenience system and can't find the option for all door unlock, only options for horn sound when unlocking / locking etc. Has anyone recently changed the 2005 vrs fabia to all door unlock, need some pointers on where to find adaption. :-) Thanks!!

IIRC it's a coding option, not adaptation.

yeah, its a coding option, just +1 to what ever the code is. ie. if its 00066 youll put in 00067.

Any ideas where it is on the VAS-PC software?

I don't fella sorry

Not sure if VAS does coding. Is that what the dealers use? Easy to do on VCDS, module 46, coding 07, add one to the number deactivates selective unlocking.
