Do you have an early A4 chassis TDI? Odds are you have a blue 4 pin coolant temperature sensor.
Later years use the green sensor which we also stock.
Look at your connector to be sure - the blue sensor uses a rectangular 4 pin connector.
Includes one temp sensor seal and a clip (not shown)
(The green sensor uses a round 4 pin connector.)
