Install the new battery, making note of its technology and capacity in Ah. Start the car to ensure it actually works, maybe do a 10min drive. Install the Car Scanner app on your phone and upgrade it to the pro version. Plug the ELM327 dongle you've bought into the car's OBD2 port, turn the ignition on (no need for engine to be running) and connect to the dongle with the app. Code the new battery's technology and Ah (if different to currently stored) in the app. I don't think manufacturer matters. Roll the battery serial number on by one - this is important, as it ensures the car knows to reset the battery management system. Close the app connection, turn car off, job done. Optionally, reconnect to the dongle and double check the current battery details are showing as you just set them. This may be useful: https://www.youtube.com/watch?v=_qAHF5nMDis

I used a generic wifi ELM327 dongle that cost me £6.50 in 2016, worked perfectly fine. If buying new now, I'd probably go with one of the Bluetooth ones recommended by the app: Choosing OBDII adapter – Car Scanner ELM OBD2 The Vgate ones are about £20 on eBay.

Ideally as soon as you can, use something like Car Scanner ELM OBD2 to register the new battery, and change the type back to EFB if needed. Be surprised if it's actually been registered as AGM in the first place, they probably just slapped it in - which may well be why it's died.

Ask/pay for the refrigerant recharging again. If it passes an initial leak test but only works for a day or two, there are two probable causes: If you're fortunate: leaking from condenser due to stone damage. ££ If you're not fortunate: leaking from evaporator, which requires full dashboard dismantle and reassembly. £££££ PS: it could also be leaking from somewhere else of course. However you should note that the compressor on these is belt driven and runs all the time, so be suspicious if a garage immediately tells you that needs replacing (get a second opinion).

@oldbloke Sent you a PM.

The high level brake light comes out with some trim removal tools, just need a wide and thin one to work in and lever it out. It doesn't seem like it'll come out at first but be patient and it will. Be gentle so you don't snap the clips. It's worth ensuring the area is pretty clean first, so you don't scratch the surrounding paint by pressing on any grit. The hose comes in from the left and goes across the light to the nozzle on the right hand side.

Kick off and threaten to invoice them for your wasted time whilst they went about trying to find moneymaking problems to solve that you didn't ask about in the first place. About £600 per hour should cover it I reckon. So annoying.

Our 2016 Mk3 estate did not have a grille, hence why I bought one. 👍 When I read up on it, I found a load of posts on the Drive2.ru site whose car was the same. Perhaps ours was just lost, apologies if this is not the case across the board. Can't edit my previous post now.

Ah maybe the facelift has the grille as standard, ours is a 2016. 👍 The scuttle cover is fixed into a channel at the bottom of the windscreen, just lift/bend it up rather than trying to remove it from that channel. As far as I'm aware the drains just go straight down into each wheel arch, easy enough to test by using the front washer and watching it dump all over the floor. 🤣 PS: the aircon serves as a dehumidifier, not using it at all times may be adding to the problem. I get your concern though, I would suggest taking it somewhere to be looked at because it sounds like a pretty serious drainage issue for the carpets to be getting wet.

You don't need to fully remove it to get your hand under, just pull off the rubber trim at the bottom edge and lift up the cover from the corner. The rubber trim holds the cover and metalwork to each other. Another thing you definitely should do is clear out any crap behind the front wheel arch liners (the side behind the wheel, nearest the doors). Only a couple of torx screws to remove. I bet there's a ton of rotting material in there, holding moisture. There was on ours. Just to add to your other post, there's no grille/filter on the intake opening as standard. If you saw a cover, you may have had the AC set to recirculate which physically closes the hole off. I think it's a bit ridiculous for the intake to be completely open so I bought a VW grille, same part fits various models and it just clips into the opening. Part number is 5Z0819044.

£97, flipping 'eck. Glad you're sorted but I think the OEM part is Mahle/Behr, they're £30-£40 on eBay etc.

Looks like a Mk2, 2015 registration but matches this diagram from the 2014 model year. https://www.startmycar.com/gb/skoda/fabia/info/fusebox/2014#anchorfusebox1 You need to rotate the image 180deg for RHD.

Could you not just buy a single 16in alloy wheel? Loads on eBay.

USER ERROR! 🤣 Just remembered that I'd previously disabled wireless Android Auto in the settings, on the assumption we'd never need it. Turned that back on and of course it works. What a clown. 😂

FWIW my cheap dongle appears to work (and I was able to update the firmware etc), but literally nothing happens when I connect to it via Bluetooth. I then have to factory reset it for the car to even recognise it again, which is a convoluted process of connecting wifi, wifi direct, forgetting networks etc. Hot garbage, straight in the bin. At least it was only £4.
