Hi there. We have a A6 1.9 diesel 2003. The fuel consumption went really bad and the temperature gauge stopped working. I was told that the ECU would be over fueling the engine as it will think the engine is cold. I have replaced the temperature sender and the thermostat. The fuel gauge is now working but the fuel consumption is not where it should be. Do i need to re set anything for the ECU to function properly? Any help would be great. Thanks. Ian
