How to fix the issue of the 2011 Tiguan sunroof not closing when tilted up?

Tiguan sunroof not closing when tilted up may be caused by foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance can prevent it from closing. First, inspect the sliding rails: When there is insufficient lubrication and excessive resistance, the sunroof will activate the automatic anti-pinch feature, resulting in failure to close. The main maintenance for the sunroof involves lubricating the sliding rails. Lack of lubrication over time can lead to abnormal noises, poor movement, incomplete sealing, or even jamming and misalignment, which may burn out the motor. Check the electrical circuit: Inspect whether the fuse for the electric sunroof has blown. If the fuse is intact, check if the sunroof switch is damaged. Press the switch to see if power is being supplied. If there is power, then check if the sunroof drive motor is functioning by listening for the sound of the motor operating. Additionally, the sunroof not sealing properly could be due to obstructions, deformation, rust, or poor lubrication in the sliding channels.
I know all about the old Tiguan's sunroof refusing to close! Don't force it—chances are there's years of grime stuck in the tracks. Grab a flashlight and check both sides of the sliding rails; you'll definitely find black, greasy buildup. Use an old toothbrush dipped in WD-40 to scrub it gently, and for tight corners, tweezers with cotton pads work best. Last time I fixed a buddy's 2011 model, cleaning out half a box of cotton swab-sized gunk made it smooth instantly. If it still sticks after cleaning, try pushing the sunroof while pressing the close button as a temporary fix. If this keeps happening, you'll need to replace the track sliders—you can get an upgraded aluminum alloy slider set online for around 50 bucks, way more durable than the factory plastic parts.
Volkswagen sunroofs tend to act up around the 10-year mark. When the rear tilt won't close, it's usually due to a reset signal glitch—try initializing: With the engine off, hold the close button for 15 seconds until the sunroof completes its cycle with an audible 'click'. If unresponsive, visit a repair shop to scan BCM data; often it's just poor contact in the travel switch. Don't rush to replace the entire motor assembly—used motors cost just ¥200 online, with labor often pricier than parts. Remember to apply specialty white lithium grease (dust-resistant type) to the tracks annually.
In case of emergency, lift the trunk mat and you'll find a pull cord inside the trim panel on the passenger side. Pull it all the way down to mechanically close the sunroof, but remember to get it inspected after using this method. That's how I saved myself when caught in a heavy rain last time. If left unrepaired for long, the guide rails may deform, making it harder to close tightly. Leakage could then soak and ruin the headliner. It's advisable to check if the sunroof brackets have sagged - use your phone to photograph the bracket gaps. If the left-right difference exceeds 3mm, adjust the frame screws. Hardened seals on older cars also affect airtightness; applying some rubber conditioner can help soften them.
