    Have you checked the steering cu measuring blocks to see if its seeing the cruise switch buttons/movements 100%?

    Unless wire to ecu has been damaged, then you sure the brake/clutch switch is definitely not at fault, you could try iirc connecting wires together to take switch out of equation for now, just to be 100% sure, anonomolies & all.

    Goes from steering cu to ecu, maybe via a connector aswell.

    NHN just been playing again
    in field 2 in 066 its all spot on
    but in field 4 in 066 when i put the CC switch on it shows a 1 at the end
    but pressing the button resume acc deacc dont show anything they stay at 000001 then when i switch the cc stalk all the way back it shows 000000
    does the car have to be moveing to show that part ?

    Usually when its coded, fitted etc, you can see all button/stalk signals via the measuring blocks when stationary, is this a retrofit or just yours has stopped working?

    Unless the modules got a problem, all A4's I've done I always test stalk functions fully before fitting wheel/airbag back anyway, so if its not showing all the stalk functions, then somethings up either with stalk, steering module or the switches in footwell, cant be allot else.

    but even if the brake or clutch switch was broke.
    would the the stalk functions still show in 006 ? field 4

    Well this is the question tbh, if the switches are broke, do they stop the registering of stalk actions, afaik no, as the measuring blocks take straight from the module you're in as such, not via the switches, but we're talking german logic here, just remove switches, do a temp job on the wires to simulate the switches, then test, its not that cold out there fella lol.
