@swathdiver
The BCM information is correct and the manual HVAC is selected with correct part number.

Finaly i get access to TIS2WEB thanks man.

@Doubeleive
The update is correct and i do it 2 times. If you update You cannot roll back to previous version.

have you driven the vehicle some miles/kilometers just to see if it makes any difference?

Perhaps I missed it or didn't understand... but what was the reasoning for reflashing the software to begin with???

i've been driving for week now.
instrument cluster Show the correct Temp 45 degree but in tech2 show 1 or 2 degree. So there is problem but not showing in the tech2 diagnostics.
