Hi
Can I use part number mine have 5G0969442K as the adaptive cruise control switch for my t6 transporter that already has front assist and radar.
I just need to add the ACC button and code it some how.

Hi,
I've added a MFSW to by 2017 Trendline T6 which already had Cruise Control on the stalks, so fitted a wheel without CCS as I didn't want to mess about moving the wiring (I've also got a Skoda Octavia with the same setup, so am used to it being stalk mounted).
I've got everything fitted and as far as I can tell everything seems to be working ok, but... I as soon as the van starts moving I get an error on the dash which shows the CCS logo with an exclamation mark.
Any idea's why?
Switching the CCS on and off on the stalk doesn't clear it.

*EDIT - so rereading the thread, i've double checked the 12v supply (seem fine) as I thought it could be that.
But, I'm wondering now if it's because I've connected the LIN wire to pin36. I seem to have the same problem Romar had with his. Time to rip the dash apart again I think...
