Four teeth of slippage sounds like major damage that will require a major rebuild. Dubious that it's worth it. Probably cheaper to swap a known good engine in, trouble being finding one that's known to be good at a decent price.

Maybe check cylinder compressions?

When was the car built, and how many km has it covered? Has the fuel filter ever been changed, do you know?

Acoustics of a big wide hole in cabin letting sound of fan motor out better? Will be less pumping loss too, not having to pull through bonnet vents, so will probably run quicker also?

Start by replacing passenger door switch.

It goes through the pollen filter in either mode on Fabias. Yetis too I think?

Same thing.

I believe in English English there are only two esses in gases.

Select reverse gear and the A/C switches to recirculation mode. Stops you breathing your own exhaust.

Super easy, once you get the lower dash trim off in the driver's side footwell. There's a good guide to doing that in the guide for changing evaporator temperature sensor. https://www.briskoda.net/forums/topic/61180-fabia-evap-temp-sensor-how-to-with-pics/ Download the pdf version to see the pics. Clutch switch just turns 45 degrees to release from above pedal, opposite twist to fit new one.

Yep.

Just a hard push to fit, from memory.

You can get refurb kits but a whole new replacement linkage is probably not much over £30 for aftermarket/pattern part.

Yes, 507 00 is correct. Beyond that, it doesn't matter.

Can also be dirty and/or corroded connections at any point. Green copper corrosion residue can be the clue to look for.

The £400 quoted was pre-VAT apparently, which ties in closely with what you see here.

Sure to be available still, I'd think. Ping me your VIN in a PM and I can look up part number and price if you like.

I looked at parts catalogue, and for the fronts there are different part numbers for vRS vs non. Rears same though. Some strong gaffa tape on the inside surface will probably work as a repair

It's fused at 20 Amps, probably, no harm will come from plugging in anything 'normal' charger-wise.

If you wish to know its exact build date (might be close to some of the changeover dates in the files), I can look up for you if you let me know the VIN.

@ArtisticlyFunny what year is your Citigo? Have you clicked on the above links to download the files?

@RoddersUK gave you the solution. Just do it.

I give up. If you cut it and it's the wrong one, you can always rejoin it!
