Just to add to that as a precaution to members with a similar issue, dont mash on the roof up and down button, should the relays fail.
This relay issue can cause your motor to overheat and explode.

Don't think that will happen as there is a thermal cutout, unless that goes faulty.
What puzzles me is the fault codes that came up saying that 5 or 6 sensors on the roof were faulty, when they all worked fine.
My business partner had a 2012 car with only 8k miles and it's roof was constantly failing, even though BMW replace probably all the micro switches on three separate visits. When fixed they said they had cycled the roof many times without problem.
Yet when driven away and used for a few weeks, the roof would fail again.
If on failure all they were doing was reading the codes and then just replacing the (faulty) sensors, then finding the roof was working, was that just coincidence?
The relays i replaced worked fine on the bench.
Or is there something wrong with the controller?
Or is it a symptom of the power cable call backs BMW have instigated.
I have ignored the call back, but perhaps should have it done.

With this tool I'm able to identify component or wire failures even if the roof doesn't work anymore.
Let's have a diagnostic session here in Munich to check your roofs.
Serious respect!

Those graphs seem to tie in with the readout on the Foxwell reader i have.
Early cars like mine have 3 solenoids yet the later models seem to have 4.
The later wiring diagrams show a 4th solenoid.

No idea original source.
Wiring diagrams seem a bit easier to understand than Tis.
The Foxwell just a reader but also shows real time graphs.
Only just got into it, to fix my roof problem.
I wonder if the new solenoid anything to do with operating the roof on the move.

Yes full wiring diagrams are much better when trying to understand a total system.

I have a roof opening problem too, the roof will stack the rear window on the roof but not open the boot, I'm not sure if the boot not opening is blocking the roof unlocking or the roof not unlocking at the windshield is blocking the boot opening. We can shut car off, pull key , lock car, unlock car, restart and the roof will let me reverse/close the roof back down and lock roof in rear so I can drive as a roadster. I have a little OBDII reader but it hadn't thrown any codes, BMW dealership replaced one of the microswitches on the right side/passenger side but that didn't fix. I think the wire bundle got out of the channel when a ziptie broke. We found one brown wire that was broken and resoldered in the right arm holding the rear window. After reading posts, maybe try replacing relays attached to pump? Open to any other suggestions, thanks

Sorry if this has been posted - I think it might be in one of RobbiZ4's German threads?
Is this the part we should be looking at replacing (the salmon relays - two of them):
BMW part number 12631742690 (12 63 1 742 690)
Thanks.
