I have had this issue in my Citigo too after around 4 years, and I have read about it being quite common (also in VW Up's and Seat Mii's) I would not remove the heatshield, but I would also not replace it for a new one, as that is quite a lot of work and I'd expect a new one to fail again in the same way. The heat shield seems to be quite thin aluminium, and due to corrosion and vibration it eventually breaks around the washer/clip that holds it. What I ended up doing, which has held so far for more than 5 years surprisingly well, was to improvise my own aluminium washers, from the bottom of aluminium cans (any beer or soda can). The bottom of the can is quite much wider than the original washer, and has a nice dome shape, which fits nicely, specially in the front of the heatshield. Note that I reused the plastic spacer between the new "aluminium washer" and the metal clip, to prevent the metal clip from touching directly the aluminium. The "aluminium washer" does touch directly the heatshield. I had tried first with a bigger steel washer but that only held for less than a year. I think the problem is that the steel corrodes the aluminium very fast, and due to vibration cuts thru the heatshield in its edges. I just added today another 2 of these "washers" in another 2 of the original clips which broke recently. Now only 1 out of the 6 supports is holding on the original heatshield and 5 are helped with these aluminium can bottoms. The exact way I did the washer out of the can was to cut it with a bit off the can bottom ridge, bend the ridge a bit inwards so the rim of the washer was a bit "reinforced", bored a 4mm hole in the centre for the car body stud, and did two perpendicular cuts centred in the hole (so there is 4 flaps that can catch in the stud a bit on their own). Note that even though this new washer holds a bit on its own, I still used the VW clip to hold it in place, as I'd expect it to otherwise corrode around the stud and fall off quite fast. You can see here 2 photos, one of a fully newly installed one and another of one that has been holding there for ~5 years: (The brown color in the car body and heat-shield is just an extra anti-corrosion sprayed coat)

Seems to be the same or related to https://www.briskoda.net/forums/topic/392871-airbag-warning-light/

Would seem like the same issue as described here:

Update: Clearing up the fault without replacing the part did not really help. It just reappeared in a couple of weeks. So I replaced the faulty part (The passenger airbag disconnect switch, in the passenger side, in side of the dashboard, just behind the door. The old one was a 1K0 919 237 E, but that has been replaced in the VAG catalogue by a 1K8 919 237. The part is quite expensive for what it is. Replacing it takes just 2 minutes: Open the side cover: It is just held by three catches, you can start from the bottom where there is a gap to make lever. You can use a wide flat screwdriver but beware that the dashboard plastic marks very easily. After you open the bottom catch you can open the front and top ones just with your fingers (it is not held too tight). The part hinges a bit on the back and you can pull it out. To release the connector from the switch pull the connector blue tab back. To release the switch from the cover push the two metal catches, and slide the connector through the front of the cover. Install the new part in the opposite order. Use a VAG OBD scanner to clear the fault, and you are done. Out of curiosity I took the old part apart: It has a small PCB with 2 switches that are pressed when in the "off" position, released in "on", and 4 resistors.

So I just got last week the same issue in my Citigo: Out of nowhere while driving the Airbag warning light turned on and stayed on. I did a diagnostic fault search (thru the OBD port), and got this fault code: It does indeed seem to be a glitch in the passenger airbag disconnect switch. So, by now I just cleared the fault, and everything is fine. If it does it again anytime soon I will replace the switch (1K0919237D) which should take less than 15 minutes*. But given that it did this for the first time after 8 years, it may take some time before it does it again. * The side panel is held with 3 latches to the console (up, bottom and front). Once freed, the switch itself is held with 2 catches to that panel, and has a cable with a connector in the back. This issue seems to be relatively frequent with Skoda Citigos, UPs, and Set Mis.

The issue continue without any change during this time. Today I run a diagnostic fault search on the car, and I show this one: So I'm left wondering if it may be a faulty sensor, or a faulty cable perhaps Anybody has a clue?

Thanks for the answers guys. Correct. Checked: they are opened after ignition (the outer handle opens the doors just fine) I tried a few things, including removing the fuse for the "convenience system control unit" and unplugging the battery. Did not help. It seems to me there is either some sensor not working somewhere, some broken cable, or similar. Anyhow, as everything just works fine (apart from the unnecessary attempt to open the doors on ignition and the extra clicks when opening) I think i will just let it be. If later I find out what was the reason I'll post it here.

If the doors are locked, and I click in the remote again to lock them, the car only blinks. But if the doors are unlocked, and I click the remote again to unlock them, the locks try to unlock again. It would seem like if it cannot tell when the locks are unlocked.

Here a sound recording of the noise. First unlocking and 1 second later locking. 20190912_175611.mp3

I didn't get you there. Do you mean the difference in the sound if I click the remote twice to close consecutively? The combi/estate version, meaning longer back. The full model type is "545 1F4"

Yep, just fine
