How do you tell if you have a Behr or Inzi water pump?

[buelldozer]

I need to replace my thermostat but since I'm 200 miles from the closest dealer I have to order it in. My problem is that I don't know which water pump I have so it seems to be 50/50 chance on whether I order the right T-stat. Anyone know how to tell which water pump you have without taking the T-Stat out and looking?

I don't want to take it apart and dump a gallon of coolant just to check and since the closest dealer is 200 miles away I have to order the thermostat in advance.

Anyone? Bueller? Bueller?

To take the time stat, you have to take the water pump out. Just call audi, give them your vin and that you need a water pump and they will supply it.
