I know this is an old thread...but even going back to the posts from 2015...the instructions are in your owners manual on how to reinitialize the sunroof...and it also mentions that a reinitialization will be needed when power is disconnected from the car (like replacing the car’s battery).

These instructions where in every BMW I’ve owned that had an electric sunroof (e32/e34/e38/e39/e53/f06/f15).

Hey everyone, i have a problem with my sunroof, first it stuck in closed position, then i found that reset trick but it didn’t work, now my sunroof sometimes fully opens and goes in tilt position, but it takes like 20-30 tries to open and then same to close, but the shade doesn’t run at all. Sometimes when I try reset again relay clicks few times and nothing happens. Anyone has any idea how to fix it?

Pleasw help ! My sunroof on my 745li is stuck open. I haven't open it in forever and last night I decided to tilt it then when I got home I tried to close it and nothing, so this morning I watched a video how to manually close it with the tool in the trunk and it did a little something so now it came down a little from tilted and stuck that I can't even manually do it cause it's stuck. I tried to slide it shut from the close button but it barely move a little then went back a little. I also tried the initialize process by holding down the button but nothing works. Please help !

Just wanted to add a data point -- The sunroof reset procedure wouldn't work for me (2012 wagon) unless the engine was ON. Otherwise the car would give a low battery warning and/or automatically shut off fully while I was still pushing the sunroof vent button. With the engine on I was able to complete the sunroof procedure and now my sunroof works perfectly.

(Thanks to covid pandemic, this car gets so little use it's battery is perpetually low.)

Is this the procedure you use? Initializing your sunroof. Put your fob in the slot and turn the car ON (ie don't start it - but push the start button with your foot OFF the break/clutch) Now, push and HOLD the sunroof button up (vent position). After about 15-20 seconds, the sunroof will vent. CONTINUE HOLDING THE BUTTON UP. After another couple of seconds, 15 or so (could feel long, but keep holding) , the sunroof will close, the open completely, then close completely. Once the sunroof has closed completely, the process is over. It's important that you do not let go of that button while the process is happening.

This worked perfectly for my 2019 m140i. No key slot, just press start button once with foot off brake and then do the process. Thanks 👍🏻

Hello guys! I have tried to make my sunroof react but none of the reset procedures work. Do anybody knows if there is a relay or what fuse is for 2011 BMW 128i Coupe?

 

[TheNine90]

Look for it in the fuse chart.

I dont have one! I have used the internet and appears its 5 and 12 but i tested all including those two and they have electricity. Yesterday i changes the switch panel and the motor and still. Same code shows in the panel and no response from the sunroof to move nowhere. I did all the resets in this forum and still nothing work.

Thank you Nine90! Will check those three fuses F62, F25 and F7 using the attached diagram. Hope this diagram works as i found two slightly different in the internet for my N52 engine. Will look for the original fuse chart in my the owners manual (or maintenance manual, not sure where is at) as well more careful.

OMG @TheNine90 you dont know how MUCH I appreciate your guidance!!! You were 100% correct, fuse #25 was missing most likely a friend lost it when he was fixing another issue i had before (which was exactly what i was feeling) abd at the time he was having difficulty reaching out the fuses even falling from his hand... "i was terrified". Well thats why i love to di all my mechanic, but when it comes to electrical i am still learning. I am soooo happy no faulty codes in my screen anymore, just like i love it!!! Thank you!!!! Thank you!!!! Thank youuu!!!!

PS. The reset in this forum worked perfectly after the fuse was installed!

love you BMW enthusiasts! Have a wonderful Sunday!

Help. I have a 2006 330i (E92) I have done the reset to get it to close, but I still have the sunroof error on my dash, and it will work then stop while the open only way to close it back is to reset again. Has anybody had a similar issue?

I need some help good people. I bought a 2017 BMW X1 28i Sdrive. The panoramic sunroof one touch switch will not work. When I hold the switch for 15 seconds to reset, the upper part opens all the way and closes all the way, but the shade opens only close to the middle and stops. The reset does not finish initialization. Is there any other way to fix this problem, and will disconnecting the battery cables for a few minutes fix the problem? Thanks.

 

[TheNine90]

Disconnecting will reset the modules. You can try initialising after disconnecting battery.

The initialisation is carried out through the switch of the panorama glass roof.
The switch must be operated in the "vent position" direction during the entire process.
Panorama glass roof can be initialised in any position.
Initialisation:

• Switch on ignition.
• Press and hold the switch in the "vent position" direction
• Initialisation occurs after approx. 15 seconds
• first the panorama glass roof closes depending on the position
• Panorama glass roof opens and closes once completely
• Initialisation of the panorama glass roof is completed
• the roller sunblind closes next
• Roller sunblind opens and closes once completely
• Initialisation of the roller sunblind is completed
• release switch when the roller sunblind is closed

You can also use diagnostic tool to initialise the sunroof.

Thanks so much thanks so much TheNine90. I will try that and get back with the results.

So, I disconnected the negative cable for about 25 minutes. I then reconnected the cable. I held up the vent button for 15 seconds. The panorama glass opened and closed all the way, but the shade open 1/4 and stopped and did not finish reset/initialization. The results are the same as before. I can open the shade little by little all the way. Just the one touch switch doesn’t work as intended. Please tell me if am missing any step in initialization. Thanks.

Initialization
Initialization must be performed on the panorama glass sunroof anytime the MDS looses positioning of the glass panels or the headliner or if the any component of the sunroof assembly is replaced.
The control button is pressed and held in the position to tilt the sunroof. Initialization begins approximately 15 seconds after pressing the button. The initialization process may take over 2 minutes to perform.
Note: The control button MUST be held in the tilt position during the entire ini¬ tialization process. Failure to hold the button will result in the initializa¬ tion procedure to be cancelled.
During initialization the panorama sunroof will operate as follows:
• Both sunroof panels enter tilt position(Headliners enter Vent Mode)
• Both Headliners open
• Both sunroof panels lower
• The front sunroof panel opens then closes
• Both Headliners close

Hello guys! I have tried to make my sunroof react but none of the reset procedures work. Do anybody knows if there is a relay or what fuse is for 2011 BMW 128i Coupe?

Ive had a few BMW and all have done this problem along the way. Every time the reset fixed the issue until the most recent last month. I have a 2013 535xi. I tried the reset and it moved a bit then went back to the fully open position. Checked the fuses, disconnected the battery and tried a reset with no success. Finally did a slow/trickle charge on the the battery over night and the sunroof worked the next day. So, it seems a low battery will impact the operation of the sunroof.

Key on position, engine off for me. In my 2003 530i (USA sold stock i6 3.0L possible M sport package); I was having trouble closing moonroof due to needing lubrication & sligtly adjusting the wind flappy thingy. I saw about the relearn process on the internet & held the moonroof button forward (towards the headlights) for like 30 seconds & the moonroof adjusted itself during that time so I thought it was all done but I kept holding for another 10 seconds or so. I then let go thinking the realern was done and tested to find that it would open fully then close only 3/5 of the way. I tried holding button towards the headlights many times and it would close then tilt after like 20 seconds of holding then same thing again. I then read this thread and tried holding the button towards the TAILIGHTS and it fully completed the process!!! I have a few tips tho... My vizor is fairly tough to move and if I dont help push it forward, the moonroof seems to struggle to close more so (Tip #1: Help guide the vizor closed as your moonroof glass is closing) (Tip #2: Keep constant hold of moonroof button towards the tailights for about 1 min or so and the process should happen and help move the vizor along as it closes.) (Tip #3: Before moonroof closes, try pushing the wind flappy thats on the outside roof down a few times "front outside edge of moonroof opening towards the headlights while moonroof is open".) (Tip #4: Lube the tracks and seals before for greater probability) (Tip #5: HOLD the button towards the rear of the car for at least 60 secoonds or until the moonroof opens and closes and tilts. Do not let go at all during this! Hold langer just to be safe. While holding I heard some very very very feint clicking of electronics from various places before it started closing.) (Tip #6: Key in ON position, engine OFF meaning the car is not running but my key is in and turned just before the start. The lights o the dash should be on.) This process worked for me when I followed other instructions and videos and they didnt work. Most imprtant for me was helping the vizor along while holding the button a long time thru the whole process
