I think the only related error is C102D00 'Tire Pressure Warning' There are others for a low battery in a key and an different intermittent issue that I think is unrelated.

On my 2019 Kodiaq the front right tyre pressure warning keeps reoccurring. I've checked the pressures and they are all fine and not dropping. When I set the tyre pressures as correct it come back within a few minutes of driving. I thought the wheel speed sensor had failed so I swapped it with a new one but it's still happening. Since I swapped it I checked using a OBD reader that the sensors are reporting wheel speeds and they all appear to be working fine and reporting similar speeds. I didn't think to check this prior to swapping the sensor so can't confirm if the original sensor was working without swapping it back. The fault reoccurs really quickly after resetting it so I don't think it would be sufficient time to calculate an actual change in pressure and like I've said they all seem to be fine and not dropping. The next thing I thought is if the wire is damaged and is causing an intermittent drop-out in signal from the sensor. I had a quick look when I changed the sensor but I will check the wire again but just wondered if anyone had any other suggestions? I didn't check under the rubber boot over the plug, potentially the wire is damaged inside the boot or connector. Any help or suggestions appreciated.

A follow up to this post. A few quid on eBay prise tools and on the first nice day I had some free time, happy to report a quick success. The interior panel around the rear seatbelt came away without damage, four (or five?) screws out of the side panel gave me access to the cables and sure enough there's the culprit. A loose cable with a white plug on the end. I'm guessing it was missed in the factory, either that or someone's been in here previously and failed to put it back correctly. Anyway, plugged in, powers on and back together in about 25 min. Thanks again for the suggestions especially to SimonB68. 👍🏻

Thanks Simon, that's really useful. I attempted to remove the trim panel but gave up as I discovered it wasn't trivial as you say! I managed through luck and brute force to remove the socket by unscrewing it without too much damage and recovered the pieces through the vent hatch which comes off easily. It was already slightly damaged in that area where the previous owner may have done the same to attempt to fix the issue. I can't see any cables and have tried both an endoscope and fishing with an extending magnet to find any loose cables or plugs. The socket has three blade connectors on the rear so could either be a plug or loose cables. Instructions on removing the trim panels would be very useful, I can see I would need to start with a section of the roof/side panel that overlaps. I've tried and failed to remove the rectangular cover to the side of the 12v socket that should give access, I'm not sure of it's purpose but it seems very hard to remove even though it moves slightly. Thanks for everyone's help.

The 12v socket in the boot wasn't working, when I eventually got it out I found it had no cables attached. I can't see any loose cables behind it, although they may have dropped down. Can anyone tell me if they are part of a wiring loom if so where does it run from? Or is it a separate cable and is there a chance it was missed off during manufacturing?
