My audi a4 1.8t fan runs so fast making noise ,draining battery even though the fan control module was replaced

SOURCE: 2000 ford expedition fan control only has high speed. Where is the module?

it is more than likely your blower motor, the control module only controls the position of the air flow, such as vent, floor defrost......

Do you have any stereo equip? Amps? Subs? Aftermarket CD player?

The main reason for the over heating of the audi tt is to do with the water pump. The propeller within the first type of water pumps is made of plastic. This was to prevent corrosion, however was never designed to last longer than 5 years. What you need to do is purchase the new style water pump. These new style water pumps have been designed with a metallic propellor which should resolve the overheating. Let us know how you get on.
