Does the car have a towbar? I had a problem some years ago when water got into back of the towing socket (grey one) which had a permanent feed and drained the battery somewhat. The kodiaq factory electrics seem to turn off the supply when there's nothing plugged in (at least the permanent feed isn't, and only comes on a few seconds after connecting the plug).

I'm going to be a pendantic 'person' here: DLR = Docklands Light Railway. DRL = Daytime Running Lights. (Or lamps). I do know that for certain LED headlamps within VW AG, they made sure dealers could repair them with repair kits and training. No idea if that's still the case.

Do they not also indicate which belts are fastened or not? So that you know if the rear seat passengers have fastened their belt?

First thing to try is as said, make sure the maps are the latest. If not update them. The issue is it's not a fault as such, just that the information in the database hasn't caught up. That will always be an issue, for example a limit near us changed the middle of last week so there's no chance the change will be even in the most up to date database.

You can see the bulb check happening on the instruments. It's turning on and almost straight off. So most likely the start stop switch is faulty.

But again, while someone, somewhere in the organisation would for sure be able to respond, it still involves someones time somewhere and therefore money (time is ALWAYS money). So there is a difference between able to respond, and willing to do it, especially for nothing. The 'experts at Skoda HQ' have plenty to do already. On the other hand, a forum like this is the place where you might get the answer. I don't have this information for Kodis but maybe somebody here does. I have current flow diagrams for older models (up to about 2012) and have looked up the info for people. Even then it can take half an hour or more just to research, and is information that I had to pay to obtain, though it's info that I can still get at. No issue with you asking for help, but I don't agree with your opinion on the support from SUK and dealers.

It depends on what they mean by 'the latest diagnostics'. There are many systems, most are generic diagnostics to work across lots of models, and most of these can't do the specific jobs like this however up to date they are. There are a couple of other ways. There is an independent but VAG specific tool called VCDS. I don't know if this can support doing this on the Kodi, but I used it when fitting the towbar on my 2012 Superb. The other possibility is that some independent garages do have the same diagnostic kit as the main dealers, and pay to get access to the same databases as the dealers so can do exactly the same work. And yes, fog has been on the 7 pin electrics for over 30 years. The same pin was used years before for a permanent battery feed which gave some problems when things wired to the later standard were plugged into vehicles with the new version.

What is and isn't fed from Kl15 and Kl30 will not be obvious. Just because something is only active when the ignition is on, doesn't mean it has a Kl15 supply. If it's CAN or LIN node then it might well be Kl30 fed and shut down via bus signals. I have come across accessory power sockets that are switched, but don't switch off straight away that ignition is switched off. So they leave power on for a while (I never found out how long) but do switch off after a while just in case you left something plugged in and went on holiday. It's possible they even use the battery condition monitor to work it out. I can see that a 230v inverter might use a similar strategy and keep running for a short time, depending whether there's a load plugged in or not. If I'm honest, I wouldn't expect anyone to hold the kind of information you are after in their head. The current flow diagrams are extremely complex (actually to my mind also very difficult to follow too). And different for every model. For the most part a technician wouldn't need to refer to them either. So essentially in order to answer your question, they need to go and search through to find the right part of the current flow diagram and spend the time to understand it and find the answers. Have you offered to pay them for this? The paid for service to get your own access to these diagrams has been offered, why are you not prepared to pay for that?

At a guess, trapped wires shorting out the squib. If you decide to investigate yourself, be careful how you do it. If done incorrectly you might get false readings or worst still trigger a bag accidentally.
