How To Reset – Unstick – Fix E38 E39 BMW Sunroof/Moonroof

bmw-sunroof

Most 1997 and newer BMW power sunroofs work nearly the same way. Here are a few tips and tricks to get your BMW sunroof in working order again. This guide applies to 5-series E39 and 7-series E38 BMWs but can also work with some 3-series cars.


Lets start with a basic BMW power sunroof reset. This will help when the battery has been disconnected.
If you have changed your battery sometimes the sunroof will only let you use the tilt function. 1. Tilt your BMW sunroof up. 2. Hold the tilt button in for at least 10 seconds. This should reset your sunroof and give you full functions again.

Some BMW power sunroofs have a recovery and reset mode. PRESS IN and HOLD the sunroof closure rectangular slide button for as much as 3 minutes. During this time the roof will open, close, slide etc. to re-calibrate the positions.

If these steps fail its time to get out your manual sunroof crank tool. bmw-crank

roof-switch Put the ignition in the off position. Remove the interior lamp next to the sunroof switch, then reach in and gently force the switch panel out.

Insert the sunroof crank tool in the motor and turn. Some motors have the hole for crank exposed and others you will have to remove a plastic cap to get to it. sunroof-motor

  10. E39 03 sun roof tilts and slides open however it will only close about 90% of the way before opening again. I’ve tried resetting using the switch but to no avail. Any ideas?

    Bruno: The motor may have slipped on the track. In that case you lost that 10% of travel. The track may be damaged inside. You may have to pull it out. Not an easy job. Most people will have to take it to the dealer for that.

  11. 2000 540i 6Spd. Sunroof is closed, does nothing when using the button. Which direction do you press the button for up to 3 minutes to reinitialize sunroof?

  12. Didn’t work on mine. !998 BMW 740il Al you can hear is it clicking. Tried the crank also and that did not work.

    Any suggestions

    Bruno: Sounds like the gearing in stripped in yours.

  13. hi bruno,thanks for the informative piece!
    first i never knew what that tool was for and secondly it worked manually!
    I tried the 3 mins.wait but it didnt react should i be concerned about the motor?
    thanks

  14. Any thoughts on 2016 bmw328d sport wagon & getting moon roof AND sun shade to go back & forth together??
    I don’t like having to let sun shade to go halfway back on its own BEFORE the moon roof actually starts opening.

  15. Hi Bruno,

    The windows are closing while holding it in the off position from the key. However, the moonroof stays halfway and goes back about 5 mm. It can normally be closed from the inside scroll button. Why would he do that?
    1999 e38 740i
    Thanks

  16. Right on …. My 740IL has sat for a while. I opened my Sun roof and it was stuck open…. it worked great… didn’t have to pull out tools or any $$$””
    Thanks

    Bruno: No problem.
