OK, I'll ask again...Is the temperature readout on a B5 S4 adjustable using the Vag-Com ????

no, but
 

I'm pretty sure it's manually adjustable. Recirc button + up button.

That would just be TOO easy. I will give it a try !! Thanks !!

That just changes it to Celcius.

I guess I don't understand what it is you want to do then..

It reads a degree or two higher than actual outside temperature. I want to know if there is........
 

an adjustment somewhere, an numeric value (like adjusting the interior monitor sensitivity) in any of the controlers. That's all I'm asking!!
