Help Needed ASAP! Car overheating at dealership

2002 audi tt w/ overheating problem.
Audi has told me a sensor needs replaced that activates the driver side cooling fan. Fan is not coming on so this is why the car is overheating.
167.00 to run diagnostic on car
400.00 for sensor and labor

Has anyone had to replace this part and can i do it myself.

Driving car to Colorado on thurs am so need help ASAP.

Thanks

Some questions

Does the fan come on when the AC is turned on? It's supposed to. If so, turn the AC on when the car starts to get hot.

If the reason for overheating is due to the fan not coming on, the car really should not overheat when you are moving, only when standing still (or moving slowly). How hot is it?

I would think more the thermostat or the water pump could be the culprit. Those are known to fail. How many miles on the car? Have you changed the timing belt (and thus the water pump)?

Why not just stay there, let them fix it. Don't tempt fate and drive off. Yes, price is high for....

this, esp. the diagnostics part, but you are right there.
Let the dealer fix the sender, top off the fluid, test the car, and have them be responsible.

If you have never done this yourself, why tempt fate when you are going on a long trip?

I would have them do it...

This happened to me and the relay kept shorting out. I had to replace the wiring harness on top of the battery. It took my independent mechanic 4 hrs tracing the wiring to figure this out which he charged me for. The dealer sees these cars all day long and you're getting a warranty as well. You're already there.

Had the same issue. Dealer had to replace sensor, fan control, and the driver side fan.

Whatever happened, all three had to be replaced. They replaced the fan first as it was dead, but the fan controller was bad and killed the new fan.

Get it fixed as it can cause all sorts of other issues. In my case, the overheating caused the seal around the thermostat to fail causing a loss of coolant.
