Thanks - I'll check it out, but it's only some of the modules that ISTA cannot communicate with.
For my no heat problem, I'm beginning to suspect the auxiliary water pump. I'll get some heat after a 1/2 hour drive as if only a minor amount of coolant is making it to the heater core. Also, I cannot hear the pump when I activate heating in "rest mode". Before I dig through the wheel arch to get to it, does anyone know precisely when it's supposed to be on? I'm expecting +12V when calling for heat and in rest mode.
