Peter,
I'm not recommending installing the wrong thermostat, as it seems you were provided with during your Audi debacle. Indeed if I found the "aftermarket" thermostat to be different in any way to the correct OEM then I wouldn't install it. The fact is I could take the Behr, Wahler and "frenchie", Dremel off their respective manufacturers marks and you would be hard pressed to tell them apart. They also ran identically in my car with the exception of "frenchie" that ran a needle-width cooler as expected since it was a 80*C and not an 87*C like the others. RT
