Default JB4 No AFR/ Temp IAT Canbus Data VW Golf 1.4T Mk7.5 2018 Aus - 02-15-2022, 01:30 AM

Hi Crew,

Got a problem with the new JB4 I installed yesterday. Unfortunately I have no canbus data showing for the AFR or Temp IAT gauges or in the logs. The guages and logs do show readings for RPM, Boost, Ign and Map however. This concerns me as it means the JB4 likely isnt seeing critical data it needs to adjust. Can anyone shed some light on a possible cause or solution here?

All connections have been unplugged and replugged. Car restarted etc but no difference.

Thanks

Joe

Would going to a VW dealer to check if the OBD/ Canbus requires a firmware update help ?

Thanks Terry, orientation is confirmed correct. Are there any specific pins on the OBD plug I can use to test continuity through the cable to the Jb4 plug ?
