Genuine VAG TFSi Inline Thermostat - 4E0121113
It is common on the TFSi's for the thermostats to fail causing them to run cold/hot and to not sit in the middle of the temperature gauge. 9/10 this is due to the thermostat not operating as it should be. This can cause the car to run rich or lean which over time can damage the engine.
This is the inline thermostat which is mainly found on those vehicles with DSG. Please call us if unsure.
