Odd roof error warning

[Deepseaskateboard]

No, if it’s replaced, that should fix the issue.

They sometimes need to add in extra wiring, to fit the new microswitches.

Update
Took the car to local BMW dealers.
Their diagnostic check confirmed all the M/S & senors were working OK.
Despite the local garage clearing the codes they could tell that the 'fault' had been triggered over 250 times.

That seemed a lot to me but I've since noticed that the 'bong' and dash warning only occurs over 25mph.
Under that the red light briefly flashes on the 'down' button.

They are saying there is dodgy connection somewhere in the wiring loom.
It's booked in for early July when they will strip out all the boot trim to find it. Should take about 2 hours

When I originally booked it in, it turned out the service manager lived in the house behind me!
So he's going to take it in and bring it back for me. The dealer is about 20 mile away so will save me having to hang around or go in 2 cars.

Sounds very helpful and potentially relatively cheap...keep us updated pls

Symptoms exactly like mine.....bonged on left hand corners at speed and steep up hill sections.
Mine was the left hand microswitch in the boot

Yeah I read your thread and it was my (and a few other forum members) initial thoughts as well.
Especially when the symptoms were identical - a broken wire seems to lock the boot or at least make the roof operation fail.
But the code was for the rear shell MS, which I've since changed.

Like Pbondar said hopefully a cheap fix
Booked in for 7th July, so I'll update then

I do have a lot of info that Robbie sent to me on fixing that problem, if you need it just give me a shout

About a week ago the roof stopped mid operation again.
It always seems to stop after the boot opens and the roof shell is half in, half out of the boot.
Knowing it was a MS shell 2 issue, I reached in and 'waggled' all the wires I could find and pushed together any connections

I've also noted that if I blip the throttle the roof operation will complete, albeit a bit jerkily.
The next day I had a 170 mile round trip. Not a single alarm or since for the first time in about 16 months
I wasn't brave enough to put the roof down though
So definitely a connection issue, and hopefully I've narrowed the location down a bit for the dealer on Tuesday and they won't need to strip the boot lining out

[obewan]

Hopefully resolved
Dealer had the car today - same two error codes showing after the roof stuck 10 days ago
However, after 2.5 hours the Dealer was unable to trace any faults in the wiring or replicate the fault (either in the garage playing with the wires or on road test)
All micro-switches, sensors and control module confirmed OK
All error codes cleared

The assumption is a bad connection that I rectified when squeezing all the connectors together the last time it stuck.

The Technician said the only other thing they could do would be to strip the wiring loom down to the individual wires. (from MS to CM)
However on checking the loom it was in excellent condition with no routing issues. In his opinion further investigation/disturbance could cause more issues than it solved - especially when all seemed OK at the moment

Time will tell, just need to get my confidence back pressing the button

Thanks to all that offered support and advice

it may be related to broken wires

you could try using the signal of the working side of roof shell 2 to see what happens

Screenshot 2020-06-15 at 15.35.26.png

pin #20 and #23 play part here

in your case the right side is closed (X0710, pin #23), but not the left side pin #20 - see what happens, if you switched them or use the signal from pin #23 in pin #20

you'll find these pins in the back of the A96a connector in the CTM

Hoping someone can help me. I figured I'd reply here than start a new thread.

I have a red light on the roof open button today with bongs and various idrive messages:

*Hardtop not lached
*Roof mechanism impaired
*Roof movement impaired

I opened the boot to find condensation and the foam the roof motor sits in soaked. There's was no standing water, but water has definitely found its way into the boot.

I plugged the car into ISTA D and brings up the following code:

*A692 microswitch, rear end module closed right

Clearing the codes hasn't made a difference.

I believe the issue probably is to do with corrosion forming. Ultimately I'll have to find the source of the leak too.

I'm hoping to replace the microswitch. Can anyone tell me if it's possible to change it with the roof down.

Has anyone had any experience or can give me any pointers/advice please?

Thanks

...Is this the general location of the switch?

Hi! Glad you got your issue resolved. Is it possible to replace the microswitch with the roof up? I've no idea how I'd retract it as depressing the button won't let me.

Disregard what i said, different switch, think code is the mechanical switch, there is fix somewhere on the forum.

[warmasice]

No worries. I've got it booked in with a roof specialist in a few weeks. We'll see if they can resolve it.
