What to Do When the BMW 5 Series Sunroof Fails to Open or Close with One-Touch?
2 Answers
Solutions for when the BMW 5 Series sunroof fails to open or close with one-touch: First, check if there is any fault warning for the sunroof. If there are no foreign objects stuck, you can try manually initializing it. Start the engine and let it idle, then press and hold the sunroof button upwards for about 90 seconds. After initialization is complete, try operating it again. The BMW 5 Series is a mid-to-large-sized car under BMW Brilliance, with dimensions of 5106 mm in length, 1868 mm in width, and 1500 mm in height, and a wheelbase of 3105 mm. In terms of power, the BMW 5 Series is equipped with a turbocharged engine that delivers a maximum horsepower of 184 hp, a maximum torque of 290 Nm, and a maximum power output of 135 kW.
My sunroof had the same issue before—the one-touch function suddenly stopped working. I started troubleshooting on my own: First, I tried the reset procedure—with the car running, I held down the sunroof close button for 15 to 30 seconds until the sunroof responded—either by tilting up and down or giving a slight jerk. This method resolves most configuration glitches. If that doesn’t work, the issue might be a jammed track or an electrical fault. Use a vacuum to clear leaves and dust from the tracks, then spray some silicone-based lubricant (avoid grease, as it attracts dirt). If the problem persists, check the fuse box—locate the sunroof fuse in the manual (usually near the driver’s footwell) to see if it’s blown. Only as a last resort consider switch or motor failure, which would require a shop visit. I later found that regular track cleaning prevents many headaches, saving unnecessary trips to the dealership.
