Default From the 2.7T self study guide...

Looks like the thermoswitch F95 only controls the coolant pump and the "continued coolant function" only operates if the engine is off.

Default Ok, you're right.... just checked.. Heheheh... one of our tuners is having folks replace the wrong

sender. I am wondering now if the plugs are the same... instructions said specifically to replace the driver side sender. Heh. Funny.

Thanks again for the info.

Default as an added note...the afterrun system is not connected to the ecu in anyway.

it is connected to the A/C control head.

Default They make an updated part(green) for the Driver side as well. I've installed one.

Didn't notice I guess.
