How to Reset the Sunroof on a BMW 5 Series?

Method to reset the sunroof on a BMW 5 Series: Raise the sunroof to the top and continue holding the switch for about 25 seconds. The sunroof will then operate automatically; keep holding until it stops by itself, indicating a successful initialization. The BMW 5 Series sunroof changes the traditional ventilation method, allowing wind to flow in and create an air current that draws out stale air from the cabin. The BMW 5 Series has dimensions of 5087mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3108mm. It is equipped with a 2.0T high-power engine, delivering a maximum power of 250kw, maximum horsepower of 340ps, and maximum torque of 450nm, paired with an 8-speed automatic transmission.
Resetting the sunroof on a BMW 5 Series is actually quite simple. Here's how I fixed it last time when the sunroof wouldn't close: First, sit in the car without pressing the brake pedal, then press the start button twice to power up the vehicle. Next, locate the sunroof control button and hold down the "tilt up" button without releasing it. The sunroof will slowly rise at this point. Keep holding for about 25 seconds until the sunroof suddenly moves on its own—first lowering back into position, then automatically sliding open and closing again. The whole process takes roughly 30 seconds; wait until it completely stops before releasing the button. Remember, you must hold it continuously without interruption, otherwise you'll have to start over. If the sunroof still doesn't respond after resetting, there might be leaves stuck in the tracks or an issue with the motor—it's best to have the circuit system checked at a 4S shop. For regular maintenance, remember to periodically clean dust from the rubber seal gaps, especially in summer when high temperatures can cause track deformation and jamming.
After driving my 5 Series for three years, I've encountered sunroof malfunctions twice. It's crucial to remember the reset procedure. First, power on the vehicle without starting the engine, then firmly press and hold the rear section button on the sunroof control panel (apply steady pressure, not too hard). The rear of the sunroof will tilt up—keep holding the button for about a minute until it automatically retracts, slides back, and finally returns to position. Releasing the button prematurely will abort the process. After resetting, listen for unusual motor noises which may indicate gear lubrication issues. Regularly clean track grooves with a damp cloth during car washes to prevent debris buildup. Last time after resetting, I noticed stiff switch operation—the technician said the control module needed reprogramming, which cost 300 yuan to fix. Sunroofs are actually quite delicate; never force the switch when frozen in winter as it may damage circuits.
