What causes the sunroof of the Volkswagen Tiguan to not close?
2 Answers
The sunroof of the Volkswagen Tiguan may fail to close due to foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are foreign objects on the sliding rails or insufficient lubrication, the resistance becomes too high, preventing the sunroof from closing. Simply lubricating it may resolve the issue. Sliding Rails: When the sunroof fails to close, first check the sliding rails. There may be insufficient lubrication. When the resistance is too high, the sunroof will activate the automatic anti-pinch function, indicating it cannot close. The main maintenance for the sunroof involves lubricating the sliding rails. If lubrication is insufficient, abnormal noises, irregular movement, incomplete closure, or even blockage and movement may occur, potentially burning out the motor. Sunroof Fuse: Owners can also check if the sunroof fuse is blown. If the fuse is intact, inspect the sunroof switch to see if it is functioning properly. Press the switch to check for power. If there is power, then check whether the electric sunroof's drive motor is working. You can listen for the sound of the motor running. If the sunroof does not close tightly, it may be due to the sunroof's chute being stuck, deformed, rusted, or poorly lubricated.
I also encountered the annoying problem of the sunroof not closing when I drove a Volkswagen Tiguan before, and I've summarized several common causes. Dust accumulation on the tracks or leaves getting stuck is the most frequent issue—dust buildup makes the tracks less smooth, preventing the sunroof from moving. Additionally, the sunroof motor might be aging and failing, especially after a few years of use in the Tiguan, where the motor may hum but fail to close. Sometimes, the control module's software has bugs and requires a system reset—for Volkswagen models, inserting the key or using a button combination can reset it. A blown fuse should not be overlooked either, as a circuit interruption will shut down the sunroof. There are also mechanical problems like track deformation or gear wear. I recommend first cleaning the tracks yourself; if that doesn’t work, take it to a repair shop immediately—don’t let it become a safety hazard. Regular maintenance, such as applying lubricant to the tracks, can prevent issues in advance.
