Hi,

In looking at the Bentley it looks as though the Aux Air Valve is controlled
by a Metallic Switch that either opens or closes as it heats up.

What I am wondering is, does the power to the aux air valve heat the switch
(working something like a choke heating element on a old beetle) and that
somehow closes off the aux air valve?  Or does the engine block heat the
switch to close it and the power is then supplied to a solenoid that then
closes the aux air valve?
