The most likely problem you have is a partially stuck open cooling system thermostat. The coolant is constantly flowing through the radiator, so its not warming up as required. This in turn will increase your fuel consumption considerably. The alternator needs to be removed to gain access to the front of the engine block where the thermostat is located. Its a fiddly job, but straight forward for a competent mechanic. Another common fault also related with the cooling system is a faulty coolant temperature sender. Again a straight forward part to replace if needed.
Hope this helps you.

Why does my audi tt temp. gauge go hotter than engine temp. fans work changed thermosat , temp sensor ,and water is ok ?
Hi
i suppose i have to ask how it is that you know these temperatures are different?
is the car actually overheating?
Have you had it scanned for any fault codes?
You may have a defective temp guage...check it by removing the sender plug and see if the guage falls totally to zero...earth the guage wire and see if the guage goes to max.

I HAVE A AUDI A6 98 MODEL ,ONE OF THE WATER PIPE HAD A LEAK AND NOW IT THE TEMP GUAGE GOES UP TO 90 IN A SHORT DRIVE .
THIS IS AS IT SHOULD BE,the temp should rise after about 1 to 2 miles,VW group engines have very little water in them compared to some other makes and should get to "operating temp" far quicker than most other cars.as long as your not overheating/overcooling,your gas mileage will be at its optimum.

1988 Audi 90 overheat signal flashes on the dash
2 possible causes. The most likely is a bad multi-function temperature switch (MFTS.) This sensor is located at the front of the engine, on the lower portion of the water inlet neck (where the radiator hose enters the cylinder head.) The MFTS has a four prong connection, and points downwards. As always, check the wiring associated with this switch to make sure there are no bad wires or connections.

Other possible cause is low water level in the overflow tank.

1995 Audi 90: No heat!
I had that same problem on a 1990 audi 90.

Turns out the radiator was leaking, so the coolant kept running out causing the temp light to go on. as a temporary fix, you can keep topping up the coolant, but otherwise you are going to need to get that radiator fixed. by the way, audi 90s have TWO radiators; in my case it was the smaller radiator that had gone. 

new radiator later, and it was fixed. unfortunatley, my temp gauge has never work...

Audi A3 2002 model auto - temperature gauge not working
The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.
