Great - good to know, thanks FMIB!

Hi everyone! I just joined the forum, so pleased to meet you and I hope I can enjoy and learn a lot being part of this.

As a first step, I would like to help some of you with this problem with the automatic trunk cover in the G31. It happened to me as well two or three times and it is quite easy to solve by yourself, there is no need to go back to the dealer.

The way the car knows that the cover has been completely deployed is a sensor (I guess something like a magnet) in the left rail of it (right in the end of the slope, in the apex from where you have to manually remove the cover if you wished to take the cover off).

When the cover loses this setting point (because something inside the trunk did not allow it to reach it) you just need to manually move the cover during few seconds (maybe 5, maybe 40), putting in contact the cilindrical stick of the cover that rolls inside the rail within that apex, touching it. After some seconds, the magnet recognizes again the cover and both "plastic things" that were stuck in the middle way of the rails will move completely up and down. You can now place again the cover and it will come to the top of the trunk and will work as it used to.

With the boot open, pull the boot cover towards you until the stansions slide out of the grooves so that there is no pressure on the moving parts.

Now, with the easy access window open but the rest of the boot closed, hit the remote key close button and the moving parts will retract allowing you to put the boot cover stansions in the grooves again and the system is reset.

If this doesn't work try starting and stopping the engine and opening and closing the boot before the above.

I discovered it on holiday after bringing too much booze back from France. It's actually a proper design feature that the cover will lock with too much pressure so that a) the moving parts don't break b) it's by product is useful in that the cover can hold your stuff in place (although probably not it's primary design)

Thanks Mephistocles - worked for me

I also tried Aachener's fix but no joy in my case.

This worked perfectly for me! MANY thanks!

Hi Aachener,

Holding the load cover at the bottom of its travel for 5 seconds worked perfectly! Been driving me nuts that it wouldn’t reset. So simple when you know how. Thank you.

Great thread! Not my issue so I didn't participate but meaningfully useful information was provided by our members.

This is what a forum like ours should be all about.

[Aachener]

Happy to know the info was usefyl, guys.

Cheers!

Hi
Very very useful page, but I tried both the Mephistocles and Aachener tricks without success.
I patiently waited minutes with the Cover pulled to extremity of rails but first the stops roll up to end, I release cover to top and it scrolls down back to middle where it’s been stuck for past three weeks.
Than I tried with Mephistocles’s alchemy, opened back easy access window without opening booth, hit the closing button on keys, nothing happens.

I had also electric roof losing its zero point, it did not close to end, but in this case I followed instructions on manual and by clicking the electric roof button for 15 secs it runs a cycle all open / all close that resets the system and it was ok.

Bmw dealer is closed for summer holidays, anybody with other possible solutions?

Thanks in advance for helping!

I've previously fixed it by trying various combinations buttons/boot/east access window opening closing, but nothing this time, it looks like a visit to the garage is due, will push to get a S/W update done at the some time if it looks like this has been resolved in a newer version..

mephistocles unfortunately your suggestion not getting me anywhere here..

I have the same thing on my June 2017 g31. Been to the dealer many times, but they don't have a solution...

Hi, thank you all for posting on this thread. I have the same problem on my 2018 G31 touring. I took it to the dealer where they updated the software but the problem came back. The cover sometimes retracts properly but sometimes not ! Took it back to the dealer and their suggestion is to replace the control unit or drive because they think the motor is being overloaded - I am not convinced this is the answer. Did anyone else here have the drive/ control unit replaced and did that solve the problem?

I tried this method and it worked after about 10 seconds.

Just bought a 2020 G31, it came with the parcel tray, (but it wasn't fitted).

I fitted the assembly, but when i slip it into the rails, it just slides all the way to the top... I see the mechanism behind the rail go back n forth, but I suspect a little clip or whatver that holds the cylindrical rod in the rail is missing. Does anyone have a photo of what it should look like?

Thanks
