How to Reset the Sunroof on a BMW?

BMW sunroof reset operation method is: raise the sunroof to the top, continue holding the switch for about 25 seconds, and the sunroof will automatically stop to complete the reset. Here is additional information: 1. BMW's automotive brands include: BMW X4, BMW X5 New Energy, BMW X5, BMW X6, BMW X7. 2. Sunroof function: Using the sunroof also has energy-saving benefits. In hot summer, when a car is exposed to the sun for an hour, the interior temperature can easily reach around 70℃. Upon opening the door, a wave of heat rushes in, and many people immediately turn on the air conditioning to lower the temperature. In fact, if you own a BMW with a sunroof, simply opening the sunroof and utilizing the negative pressure formed on the roof while driving can quickly exchange air and reduce temperature by extracting the hot air. This method is 2-3 times faster than using air conditioning for cooling and also saves gasoline.

When I first bought my BMW, I was also confused by the sunroof reset. Actually, the steps are quite simple: First, make sure the car is completely turned off but in the power-on state, which means pressing the start button twice without stepping on the brake. Then, press and hold the rear part of the sunroof control button—don’t let go—until you hear the sunroof click and fully close. After that, continue holding for about 15 seconds, during which the sunroof will automatically tilt up and then back down. The key is not to release the button during the entire process, or you’ll have to start over. That’s how I fixed mine after it malfunctioned post-car wash. Just remember to do it on level ground.

Yesterday, I helped my neighbor reset the BMW sunroof, which involves three steps in total. First, hold the sunroof switch backward until the sunroof is completely closed. Second, keep holding it for another 15 seconds without releasing your finger, and you will see the rear of the sunroof slightly lift and then lower back down. Third, immediately release and quickly pull the switch backward once more to complete the sunroof's self-check. The key point is that it tends to malfunction after a power interruption, so remember to perform this operation after battery maintenance. If there are foreign objects on the sunroof seal, the reset may fail, so it's best to clean the tracks first.

The key to BMW sunroof reset lies in timing. After parking, press and hold the close button all the way for 20 seconds. Watch for a slight tremor after the sunroof closes - that's the reset signal. I've developed a habit of pressing the reading light with my other hand during the process to enhance power supply. My last reset failed because I forgot to close the sunshade. Now I've learned: first open the sunroof to let the shade retract automatically, then perform the reset operation for better reliability. Resets tend to be more responsive during summer heat.
