Hello doez anybody sniffed can messages for cruise conttrol stalk on b6 , b7 ,4f ,4e i have tried but with no sucsess , connected direct to steering wheel electronics on 500 kbps powertrain bus and  convince 100 kbps bus but module keeps silent or dont transmit commands till vcds ask . I have tried modifying CWGRABH but ecu sees only master switch byte nothing else . Or i have to call them like vcds but im affraid that can breakdown comunication when diagnostic is active .

what are you looking for? How to sniff, the CAN message IDs and payload?

The FR doc should have the expected CAN IDs and payloads.

I dont want to control ecu over can , i want to build my own controler based on messages from 4F platform and convert it to analogue signals to me 7.1.1 and i think 7.1.1 can work with can based cc just my steering colum doez not transmit messages to be used. I build arduino based engine fan controller with pwm and ac pressure controled over can last thing is to combine cruis control to it . Also it have its own Display that i plan to add boost to it .

Did your steering wheel, steering wheel module come from a car that used CAN for CC controls?
