When I put the top up on my 2001 TT the top sensor shows that the top is not locked and it keeps the windows down 1/2 inch. What do I need to do to fix this.

Use standard Automotive electrical troubleshooting techniques to determine if the sensor is not actually detecting the proper top position.If not, repair the reason this is not happening. Or, if the sensor is truly being activated, determine if the internal electrical/electronic circuit is working. If not, replace the sensor. If good, trace wiring to the module and confirm continuity. No continuity? Repair (Again, using standard electrical troubleshooting & repair techniques). Everything checks ok? Use Ross-Tech software and their genuine interface cable to read any fault codes related to your issue. Actually, you should do this first, but I presume you don't have this so I offered a few suggestions. At this point, stop and buy this cable. Wait for it to come in. Then run the test. Of course you'll need a properly configured PC to do this.
You're probably going to ask: "where is this alleged module"? You need to buy the proper service manual for the car to get this information as well as a vehicle wiring diagram. Bentley Publishers has the manual or buy an All Data subscription. Otherwise, pay someone to repair the problem for you.
If all of this turns up nothing, you probably have a defective module. Replace it, but there is a risk something else is wrong. These modules hardly ever go bad. You may need the module, if replaced, to be coded to your vehicle. That's a dealer only procedure.
It could be something else, like your door lock mechanisms are defective as they can affect the window position. Ross-Tech diagnostic scan is the best way to determine. The $20-$100 scan tools are worthless for Audi-specific faults. The convertible top diagnostics are not SAE fault codes.

I had this problem and the micro switch was not being engaged by the handle mechanism when closed. It's not hard to get to the switch in the windshield header. Take it out and bend the thin metal lever that actuates the switch. It's hard to describe, but once you see it, you'll know what I mean. Get the switch to close when the handle is locked and your problem will be solved.

Agree, this is a common Mk 1 roadster problem
