What are you available SWCM codings (16)?
All of the coding is in German, so using my Google translate the only options for cruise control are the location of the cruise control switch (stalk or steering wheel mounted). The correct option is selected (3rd stalk), but there are a bunch of LIN options that I'm not exactly sure which one is correct. I'm assuming the coding is correct.

By any chance does your steering wheel have CC Buttons?

Do you have any specifics of the swap, is engine coded for CC? ECU plays a BIG role in CC/ACC functionality...

Try this, disable Byte 2 Bit 5 and Enable Byte 2 Bit 6
Unfortunately, that didn't work either.

I'm thinking it has something to do with the ECU since it's getting the signal to set CC, but it just refuses to set. It looks to be coded correctly for CC and manual trans. The ECU is straight from a manual car. Previous owner told me he got the engine and Trans combo out of a GTI, so maybe it has something to do with that, but again, all part numbers are correct and the ECU is not complaining about anything.

It could be that since this is a VW CC it may not have come with regular CC and could have had ACC, try coding ECU and SWCM for ACC.

Unlikely in an NAR model of that vintage.

Yes, but as nothing else is working maybe he could put in a radar and get adaptive cruise.

I’ve looked into this a bit, seems CC never had a manual from factory, so it may be related to that
