Where is the temperature sensor on a Audi tt?

In an Audi TT, the temperature sensor is typically located in the engine coolant system, often near the thermostat housing or in the radiator. It monitors the engine's coolant temperature and sends this information to the engine control unit (ECU). In some models, there may also be an additional ambient temperature sensor located in the front grille area. Always consult the specific model's service manual for precise locations.
