Check fuse #11 (7.5 Amp rated); often overlooked. If that is intact, also check that with ignition switched on, the feed from it gets to the 16 way connector at driver's side window motor, pin no.6, a black wire with blue stripe. Convenience mode can work even if this feed is broken. I'd guess with some confidence that this wire is broken between A-pillar and driver's door, in the bellows section where the wires flex.

All engines will have a joiner there, but different (bigger) sizes for the diesels and 2.0 petrol I think.

That's front pipe to midsection though, isn't it? Always a joint there; it's mid and rear sections that come as one.

Which joint? From memory, the front pipe to midsection sleeve clamp is 45mm ID, the mid-to-rear one 38mm. Message me your VIN if OE part numbers may help.

Probably the control module version of the resistor pack failed short circuit. Current part number for RHD cars is 6Q2907521B. Awkward to access/replace on mk2, I seem to remember.

Oops. 😁

Is that you admitting to driving badly? 🤔 If so I applaud your honesty.

Yes, but doesn't excuse their failure to look sufficiently.

The two/four numbers shown in my earlier post are all unavailable from Skoda, but not long ago dropped in the case of the suffix-C pair. LLL parts are presumably finding new old stock in warehouses, temporarily. If you message me with your VIN I can give definite correct part numbers for your car. Pretty sure it's the suffix-C ones, but happy to check.

Odd, on small screen and struggling a bit, but 8 seems not to be listed, and 9 is as shown in the table.

Not sure those are roof rails Lee, maybe just trim bits. Will look at descriptions...

Look near the end of page 2 of this thread, there's a video of how to install rivnuts without spending lots on a tool:

Various sites have ETKA-originated stuff, like this one Skoda Parts catalog - ETKA Online, Skoda EUROPA, original Catalog Skoda EUROPA (7zap.com) LLL parts' one tends to be more up to date. LLLParts

The last image shows a horizontally slotted plastic part just to the left of the thing you're holding; probably where that assembly is designed to be held? The screws that are loose and missing appear to be items 18 and 17 here, but as it appears to be only a belt cover, I'm not 100% sure this will solve your leak, unless the belt runs wet?

While looking at what part numbers to search, I did note that there appears to be two versions, of which the newer one isn't apparently just a supersession of the older (A-suffix). So avoid sourcing from cars that are earlier than MY2003. The changeover was some time in MY2002 (tenth digit of VIN=2). No idea what difference there is but both variants are discontinued:

Dunno if they really have availability, or if you were thinking of spending serious cash to solve this, but LLL parts seem to have new genuine available: 6Y9860025C and Skoda Roof Rail 6Y9860026C - LLLParts both there.

The prefacelift ones seem to hardly ever fail, in comparison to the later ones.

2nd and 3rd images here suggest Mahle is an OEM on this part: https://www.ebay.co.uk/itm/265058476573

Oh, wait, is his pre-facelift? If so window motors not so useful.

Driver's one particularly.

It seems not. Hmm. Any history of trouble with heater matrix leaking? That's immediately above the airbag ECU.

I'll look at the circuits shortly. I wonder if these items share an earth, spliced into the main cabin loom somewhere that might get damp...

Sorry, must have looked too quickly, as I thought I'd seen both faults swapping sides. No idea what connectors there are peripherally, but I think the airbag ECU is pretty unlikely to get damp in its location, so start at crash sensor and seatbelt reel. Where is the relevant crash sensor? Water ingress tend to leave green crusty corrosion products on copper wire and connector pins.

Looks to me like the ECU you bought may be for a LHD car, so it thinks right side is passenger side? Always best to stick to exact part number matches including suffix, unless you have concrete information as to compatibility. You should be able to clear airbag faults with VCDS (including the freeware version VCDS Lite, which you can download from ross-tech.com). Then a cheap (<£20) KKL cable to connect car to laptop and you have tip-top diagnostic capabilities. You'll have to find and fix the problems first though, which I would hazard a guess as being corroded wiring connections.

Depends on your health and lifestyle today, probably.
