Heater valve

[George]

I believe the type 44 chassis prior to the 200 20 valve did not have the
electrical connector. Audi, in its infinite wisdom saw the need to have
electrics on the valve on the 20 valve, which I would respect as it
obviously had a purpose..........   

The dysfunctional co-dependencies between the ECU and the delicately
balanced Audi electrics is not something I would be inclined to tempt the
fate of.  No telling what that imbalance and Audi gremlins would visit their
wrath upon you.
