Your assumption seems correct to me.

In the Fabia guides section there is a guide for changing the aircon evaporator temperature sensor. Find it and read. To get to that sensor you have to remove, or at least move the CCM it's up above clutch pedal on RHD cars.

Agreed, but knowing the motor trade, they'll battle to avoid any cost to themselves.

Assuming the latch with microswitch is in the moving/tailgate part, it could also be a wire between that microswitch and the BCM, broken in between moving tailgate and body?

Not sure, I searched my document for 'torch' and 'flashlight' and found reference to neither, so suspect it is a feature newer than the diagrams I have.

I think your wiring loom will be very incompatible with such an item.

I don't have latest diagrams for Superb so it may have changed, but the microswitch for the luggage compartment lighting is within the 'rear lid lock unit' F256 on the ones I do have. Such microswitches can fail either mechanically or electrically, although your car seems very young to have suffered such a 'wear and tear' problem.

Fair enough. Would've been clearer if I'd written "on the same circuit board".

Isn't that exactly what I said? Or is this a Greenline?

CAN gateway will be a sub-module of the vehicle voltage control unit above accelerator pedal on that age of Fabia, I think, same as on mk1.

Radio PIN code might be stored in instrument cluster (on mk1 Fabia?). I think I read that somewhere once.

Scroll past instead of posting, and they soon die...

I believe @Crasher has a lot of experience in this area.

That thread actually has a link back to this one. An even scarier pic halfway down page 1

Not necessarily a good place for a cheap sensor, the genuine ones may not always be able to survive the environment. https://forums.tdiclub.com/index.php?threads/dpf-pressure-sensors-melted.514897/ To be fair, I haven't read that thread to know if that was an OEM one.

Found one of the threads where relay faults have been found to cause fan issues: Radiator fan coming on randomly... - Skoda Superb Mk III - BRISKODA Don't think it's the exact thread I was thinking of, but it looks like it could be relevant to at least part of the OP's troubles.

Ask the garage to remove a little.

No, but they may have simply refilled with a bit too much. What oil does the invoice say they used and what quantity? When you checked it and found it to be just within range, was that with a cold engine, or once warmed up?

The way I read the OP, it happened a long time after the engine last ran?

How would explain fan running when engine off?

I'm having a vague memory of a (engine ECU?) relay in the engine bay fuse/relay box that's been responsible for odd fan behaviour from time to time, replacement fixing it. Anyone got a good enough memory to track down such a thread? I remember expressing doubt that it could possibly be involved, and emerging with egg on my face.

Look to be, item 15 on same page, just the one part number for all.

Handling ought to improve once sorted!

Wiring info shows 2 EGR valves, so probably true. Not sure on the physical arrangement though.

How did it get bent, that must've been quite a knock?
