Hi,
I don't know if this has been discussed before. I have a Golf mk7 Trendline (2016) and for the last week or so I've been trying to install the Multifunction Steering wheel and get it fully working.
So far:
-the CAN Gateway has been switched from low to high, so right now I have a fully working Gateway High (no CP).
-The multifunction steering wheel is installed and controls are mostly working (multifunction display - it's a trendline so it's the low version, + media controls).
-The 'extra' cruise control wire is installed (ECU pin 56 - steering wheel controls pin 5 if I remember correctly)
I have issues however with activating cruise control. Both cruise control and the speed limiter have been activated via VCDS in Engine and Steering, but when at least one of these two is activated, I get an error in Engine:
"Check Coding of ECUs on Powertrain Data Bus"
and when Cruise Control is activated, an error also appears in ABS as well.
Cruise Control shows "ERR" on the display, but the speed limiter works just fine apparently. So the best guess right now would be that some sort of coding needs to be done on ABS side as well in order to prepare for CC. And for the Golf MK7 at least in VCDS for ABS, there's no helper, and there are 60 bytes to code...
I've seen successful retrofits with instructions for cruise control via the signal stalker, but not on the multifunction steering wheel so far, and it would be a shame to just leave those controls there with no function. Can anyone help me with the missing coding?
