I've been on the DIY coding thread and found a member on the 1er F21 forum that coded his M135 to display a colored graphical temp gauge but with no temp value. The fact the gauge is actually there leads me to believe there must be another value somewhere that needs to be coded to make it functional. Hopefully someone well versed in coding can chime in here.
KOMBI ECU, 3000 Module, BC_MOTORTEMP_ENABLE changed from Nicht Aktiv to Aktiv.
