If the sunroof switch malfunctions, it may be due to an issue with the sunroof control button's microprogram. Performing an initialization of the sunroof control button can resolve this. The initialization procedure is as follows: Turn on the ignition switch and ensure the sunroof is fully closed. If the sunroof cannot close normally, you can use either electrical or mechanical force to close it. Press and hold the sliding or tilt switch and operate the sunroof in the following sequence: tilt up → hold for about 1 second → tilt down → slide open → slide close. The initialization is then complete. Here is additional relevant information: 1. After completing the setup, verification is necessary. Check whether the sunroof has automatic open/close functionality and whether it has an anti-pinch feature. Engage the parking brake and close the sunroof. Press and hold the "UNLOCK" button on the remote for more than 2.4 seconds to check if the sunroof opens automatically. After opening, press and hold the "LOCK" button for more than 2.4 seconds to check if the sunroof closes automatically. If these checks are unsuccessful, reinitialize the sunroof. 2. Octavia Sunroof Closing Method: Disconnect the negative battery terminal, wait for ten minutes, then reconnect it. Open the sunroof fully and hold the switch for 3 seconds. Then close the sunroof fully and hold the switch for another 3 seconds. The manual reset learning is now complete. Pay attention to the lubrication of the sunroof tracks. Insufficient lubrication can lead to noise, poor movement, incomplete closure, or even jamming and misalignment over time, potentially damaging the motor.
