How to Remove the Sunroof Control Switch on a BMW 1 Series?
3 Answers
To remove the sunroof control switch on a BMW 1 Series, follow these steps: Press and hold the sunroof switch vertically upwards for 30 to 60 seconds until the sunroof completes a full cycle. The sunroof switch is located in the overhead console near the front reading lights, which also integrates controls for the driver-side reading light, passenger-side reading light, sunshade, and interior lighting. The BMW 1 Series is positioned as a compact sedan, with body dimensions of 4462mm in length, 1803mm in width, and 1446mm in height, and a wheelbase of 2670mm. In terms of features, the BMW 1 Series interior includes a three-spoke multifunction steering wheel with four-way adjustment, an 8.8-inch central display screen, a keyless start system, and an optional keyless entry system.
I've got experience removing the sunroof switch on a BMW 1 Series. First, use a plastic pry tool to start from the edges of the overhead light panel surrounding the switch. Gently pry open those hidden clips, and the entire panel can be removed. The sunroof switch module inside is usually secured with two screws, which can be unscrewed using a T20 Torx bit. The key is to disconnect the negative battery terminal before unplugging the wiring harness, otherwise you might blow a fuse. Remember to take photos to document the connector positions before reassembly. Don't use metal tools to pry forcefully, as scratching the interior would be a big loss. The whole process takes about half an hour, but be gentle—BMW clips are particularly fragile.
Last time I helped my neighbor dismantle the sunroof switch on his 2018 1 Series, I discovered some tricks. The sunroof control module is hidden behind the overhead light assembly, so you need to pry off the plastic cover of the sunglasses holder first. Use a trim removal tool to slide along the gap, and with a click, the clip will release. After removing the entire panel, there are two wiring harnesses hanging—the black connector is for the sunroof. The key is to press the small clip at the base of the connector before pulling it out. All you need are a T20 screwdriver and a plastic pry bar, and doing it yourself can save over 500 in labor costs. Remember to disconnect the battery before removing any wiring—last time I didn’t, and it triggered a fault code.
