2004 audi TT roof opens by switch but won't close

The roof opening panel is an electronically operated panel that can be opened or closed by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor. The vent and soft-stop functions are controlled by the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof position switch, removing the ground from the switch. The roof opening panel has an express open feature activated when the switch is pressed momentarily. The roof opening panel is closed by continuous activation of the switch until the sunroof stops movement. This function is controlled by the roof opening panel motor.

• Disconnect: Roof Opening Panel Motor C920.
• Key in ON position.
• NOTE: Activate accessory delay relay for this check.
• Measure the voltage between roof opening panel motor C920-4, circuit 400 (LB/BK), and ground; and between roof opening panel motor C920-7, circuit 1173 (BN/OG), and ground.
• Are the voltages greater than 10 volts?

Yes
GO to E7 .

No
REPAIR circuit 400 (LB/BK) or circuit 1173 (BN/OG). TEST the system for normal operation. If you can't do electrical testing , there is a manual way to close it .
Roof Opening Panel Manual Operation

1. Insert a hex-head screwdriver in the center of the manual drive slot to depress the release pin. Rotate the screwdriver clockwise until the roof opening panel is closed.

What year..? Sounds like the motor is going bad. Sometimes they work intermittently or will work with higher voltages.

In Hondas and Chryslers its on a little skinny white sticker on the side of the glove box when open. No clue on an Audi, though. Good luck hunting!

loose connection or faulty relay

Look in owners manual,it will show you how to raise/lower roof with tool end of dash driver side
Once you have the tool the best way to reset roof is to manualy lower it and lock rear cover
Two people helps to lower as you have to lift front of roof and lift rear
When rear metal cover is unlocked push roof fully down and lock cover
The roof should then work with the switch

I believe that the motor went bad on you that lets the roof to open or close but also you could have a connection problem or short in the wires. Have you in the past heard the motor move the roof open or close or never noticed it at all?

Does your windows close fully? this could cause conden if one is slightly open.

Yes if you go into the trunk you will find a small passage to get to the pump there will be a little T- shaped knob on top turn this untill it stops and you will be able to lift the top to close it.

I had problem with the flaps staying open,pilot error you have to have the engine running and it's fine wish the dealer told me that. The only problem I have is when the roof has been down for a while , when it's then closed there is a small bump that appears on the near side.

Release the hydrolics in the trunk. Then pull the top manually into place.
