Hi all.
I have an Audi A4 b5 1.8T (1999).
I have an issue with the temp gauge and oil gauge not moving off the bottom mark even though I have done the obvious jobs as follows:
I recently changed thermostat as the car was running cold when moving and warming up to 90 when at rest. This went fine and temp gauge worked ok afterwards. (Oil temp looked low at around 90 degrees but guessed this might be OK as matched water temp).
I then had the waterpump changed as it was knackered and rattly. This also went fine and all was well afterwards.
Then one morning I noticed water temp and oil temp gauges were both not moving at all. I checked the ECU temperature off the climate control panel and it went up to 90 and sat there as expected.
I therefore changed the temp sender at the back of the head for a new green one which made no difference. Gauges still don't move.
Please can you tell me what other sensor or part may be responsible for this behaviour? The Speedo, Rev and petrol gauge are all fine. The screen in the middle of them has some lines on it, but always has.
Any advice would be appreciated. Is the Multi Function Temp Sensor (MFTS) anything to do with this?
Thanks,
Tom
