Thanks Hi its usually on the fuel return pipe from the fuel rail. Steve. Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted March 11 Share Posted March 11 I did not know a fuel temperature sensor existed on A3s. What is its purpose? I could understand diesel temperature being important in cold climates because diesel can throw a waxy sediment when it gets cold, but surely not in Newquay?

Hi Cliff they are on all later cars as the sensor lets the ECU know the temp of the returning fuel from the rail, this is because part of the returning fuel is used to supplement the level in the filter housing when the car is under heavy load, most of the fault codes that are thrown up by this sensor are either due to bad wiring or most likely air bubbles in the return where it can't read warm air.
