I'll certainly criticise when I read (as RobbiZ4 would say) these "crazy stories" from uninformed posters.

This is a highlty regarded forum and new or prospective owners come here for informed advice. They should not have to wade through messages and try and decide which is accurate and which is mystery and imagination. Don't you agree?

I’ll tell you what, if your roof motor merely melts & doesn’t actually burst into flame & you feel aggrieved by this (which you obviously would)
I’ll come round & torch your car for you.
Happy now? :P

Next update.

Returned home to Sussex without any further issues. Since we weren't touching the roof, I'd decided to retract the shelf in the boot to give more room for luggage etc and coincidently or otherwise have not had even a whif of an alert for a day or so. Is it possible that the collection of sensors and microswitches regarding latching etc 'shutdown' because a fundamental one connected to the shelf position isn't going to let you try to lower the roof?

Next up is to find an independent BMW garage (don't want to pay dealer prices unless things get desperate) who can have a look at it all.

You may struggle finding an independent garage who know what to do unless it is very simple. Seems to be a dealer, or a roof specialist job from what I've seen.
If you have a decent code reader, are able to do any work yourself, then give RobbiZ4 a shout who will advise on what to do :thumbsup:
All good things come to those who wait. I'm really impatient which explains a lot.

Looks like the infamous microswitches that RobbiZ4 recommends being replaced as service items.

Seems the discussion also suggests fitting of buzzer to warn relay contacts haven't opened.
We have the same in aviation, on the instrument panel the CAA mandate a starter warning light.
Years ago an acquaintance told me he was flying mechanic on board a Dove aircraft.
The starter had stayed engaged and caught fire.
So warning light had to be fitted, but usually only on coil side of relay from what i have seen.
Really needs connecting to the contacts.

Yes, as explained by RobbiZ4 on P1 of this thread:

Yep, in Robbie own words the pump has been burned. I knew I’d read it somewhere.

It does look as though Robbi is suggesting the motor would get extremely hot and melt itself, rather than burst into flames, at which point perhaps the circuit would be destroyed and nothing further would occur? Not sure, I'm no expert on electrickery at all.
However, I do think Rob has a point too. Whilst the motor may not burn, the heat generated by it could conceivably be enough to set fire to insulation etc.
Regardless of whether it melts or burns, I would not want something reaching that temperature in the boot of my car.
Following Robbi's suggestion of disconnecting it would seem wise to me.

Always happy to help if I can.

If the forum helped you, why not help the forum back. Thats the Z4 way! :thumbsup:

No no real-world experience then?

I don't understand why people post their "wonderful advice" when they really don't know anything about the subject being discussed?

See Robbi's advice (above). He actually has the real-world experience.
Just to reply to your rude & ignorant comment about “not knowing anything about the subject being discussed”
I worked with DC motors & electro/hydraulic motors for the best part of 20years, my experience also includes fault finding on relay interlocking circuitry. Prior to that i installed & commissioned battery backup systems for the National telephone network.
I’m not sure what you bring to the table apart from a penchant for sarky comments? Maybe you could enlighten us as to your technical prowess?

Anything electrical has potential for catching fire. I have used a fire extinguisher 4 times on electrical equipment to put fire out.

The subject being discussed is the fact that (according to you), the pumps can burst into flames, if a fault lets them run continuously:
Smartbear wrote: Tue Sep 07, 2021 10:31 pm they can burst into flames!
This has been refuted by other posters, speaking from their experience. You attempted to justify your claim by spuriously quoting RobbiZ4 who actually said nothing of the sort. Overheating and melting of internal pump components is not "they can burst into flames!".

Rude and ignorant?
