Audi Coupe GT temp sender question

Well, they are easy to test... just remove it, bring it into the kitchen 
along with your ohm meter, and prepare a container of ice water and a 
pan of boiling water.  When it is soaking in the ice water, it should 
read fairly high, around 2.5 k ohms as I recall.

In the boiling water (be careful of the heat, and make sure your heat 
source doesn't hurt any of your wires) the resistance should be down to 
around 100 or so ohms.  If that checks out, it's fine.

Parts cars, usually.

By the way, did you replace all those molded vacuum and PCV hoses yet?

Recheck control pressure actuator current at warm idle?
