Audi Thermostat OEM part number 06E121111AT is a used genuine part from a donor vehicle. This thermostat, also known by superseded numbers 06E121111AS, 06E121111AR, and 06E121111AN, controls engine coolant flow to maintain proper operating temperature. It fits 3.0L V6 engines including the diesel TDI, supercharged TFSI, and MHEV turbocharged variants found in Audi A5, A6, A7, Q7, and S5 models. A failing thermostat can cause the engine to run too cold or overheat, with poor heater output or a check engine light.
