How to Replace Roof Sensors

[Fatb10ke]

Beeping fixed, speaker wire cut! Simple.

We had a very stormy camp overlooking the sea in summer 2021, and forgot to bring the roof cover, so it turns out the driver's side took a good good soaking of salty spray.

Fast forward to 2025 and we started to get the warning bongs that the roof is still up, and the roof open icon on the control screen. Thanks to this thread, I identified the most rusty sensor (in fact the top bit fell off when I checked it).Then ordered the part. Cut the wires and soldered to the new sensor one by one. I didn't bother disconnecting the battery or removing the relevant fuse, just was extremely careful not to short the wires to ground or each-other.

1hr later and all working fine again. See photos.
Thank you to all for the instructions.

Just did all this on my California today, ordered from BMW, £67, fixed it within an hour.
Can't thank you all enough.

Mine has just developed the same problem. Code 1000 that won’t clear. I can’t open the roof though!! Any ideas how to do it manually so I can get to and change the sensors?

Roof jammed whist on holiday

I wonder if anyone can help, I'm currently on the west coast of scotland in my 2007 california All was well till this morning, we'd woken up but were still lying in the upper bed when there was a loud clunk from the L/H roof support. Subsequent investigation showed that the hydraulic ram...

Just had mine replaced by Kernow transporters. Richard fitted them while I went for a coffee down on Marazion beach ( overlooking St Michael’s mount) which is a 10 minute walk away. Cleared the front drivers drains while he was at it! Took him about 2 hours as the roof was locked down and had to be raised electrically after removing part of the roof lining.
Great service. All for £325!

I've read through the tread, can anyone say if this applies to the VW cali 2023 model with the large control panel with a rotary knob? My fault seems to be slightly different. I'm not getting the 1000 code just a message saying Errorop-up roof. Please visit workshop.

Mine sometimes sticks half way down and i need to switch the ignition off for a while before it will clear the fault and let me put it down.

I've read all the info and im ready to replace the sensors but not sure its the same fault. If it was the closed sensors, why does it stop half way down.?

Hey all,
I started getting the dreaded Bongs last year in September. I had travelled/lived in it for 4 1/2 years but rarely used the roof so when I did decide to raise it, last year, it was reluctant to come back down again. Eventually it just about managed to convince itself to lower and lock but I wasn't in a place to investigate (and was in an apartment provided by work).
To temporarily stop the bongs, I performed a Roof "Delete" from the console diagnostics page. There, you can simply tell the controller there is no roof and it stops trying to monitor or warn about it (no bongs!) and stops displaying a roof symbol of any kind.
Its just a menu option that you can turn enabled or disabled, for my late 2017 T6 Ocean, anyway.
Ive now had the needed hall sensors in my possession for the last 2 months and will be swapping the sensors tomorrow. Hopefully Ill find a 12v feed to piggyback if I need to manually raise the thing!
Big thanks to all who have journeyed this particular path before me and have taken the time to document it.
I'll do my best to record something useful.

Sadly another owner now with this problem! Exact symptoms as others, 2018 Ocean.

DIY not my strong point at all so wondering if anyone has had this repair done in the Essex area? I could travel a couple of hours out, so Suffolk, Kent etc all fine, just hoping there might be a recommended company / person that others have used that could do this for me.

Can't stand the thought of having to give VW a huge amount of money for something that seems such a common fault.

Thanks

Hi Egena - thanks for replying.

I dont seem to be able to message you, not sure if it is because I am not a VIP member ?

Only VIP members can use this service.

So a decision. £1000+ to VW or £14.99 for Forum membership?

 

[Lambeth Cali]

I used these people to fix my sliding door. They may do sensors if asked.

Does anyone know where I can get 4 hall sensors from?

I tried Synter bmw which came up when I googled the part number but they have said these are no longer available.

Any tips?

Got mine from EBay.
With BMW official you had to claim to own a BMW.

 

[Rooney1000]

I have been searching today - only place left to get them seems to be ebay and they are on their for £118 each ! I think they retail at about £18 if other places have them in stock.

Anyone aware of somewhere that might have them ?
