I just last week had a 90.5C thermostat installed in my S4. The old one was
completely shot and stuck open, therefore the engine never reached its proper
operating temp. The 90.5C thermostat is German made, fail safe and the engine
heats up fast now, also the interior doesn't take 20km. or more to warm up.
I am very pleased.
