I also think the EPB is necessary for TJA to work. Why? Because when the vehicle is stationary in a traffic jam TJA needs to be able to apply the 'parking' brake otherwise the car will either creep if left in gear with the clutch engaged or will roll if the clutch is disengaged, and hence needs the EPB.

IMHO that's very bad - service history WAS available until they "updated" the app in December 2020, so to not restore a feature that was working for up to a YEAR is IMHO ridiculous. I've also contacted both Skoda UK and Skoda in Czech and had a similar response that "it's been referred back to the developers".

Remember to connect the charger to the battery positive terminal ans IMPORTANTLY NOT the battery negative terminal but the tag on the body where the negative lead from the battery is connected (this is to avoid confusing the battery management system on the car).

This was quite a common problem a few years ago on Audis - the heated rear screen was used as an antenna as well as a heater. To prevent the interference getting into the radio signal Audi fitted an in-line filter that separated power and radio signal - this filter would fail and produce exactly the symptoms OP describes. IMHO worth checking if this combined heater/antenna arrangement is used on the Mk3 Superb and if it is then I would get the filter replaced.

BIOS updates only happen infrequently (unlike Windows updates which can be one than one per month). Unlike a failed Windows update - which can be recovered from by a (painful) reinstall - a failed BIOS update will often brick the computer, so the best advice IMHO is to only do a BIOS update when absolutely necessary. I've only had to do a BIOS update once in nearly 20 years of PC ownership - when the original BIOS wouldn't support more than 2GB of RAM and a BIOS update added support for up to 16GB of RAM.

I had the direct TPMS system on the Audi I had before my Octavia - after 9 years and 6 sets of tyres (it was an RS4 so it needed new tyres every 10k - 15k miles) it was still working perfectly when I sold the car.

The 1.0, 1.4 and 1.5 TSi engines ALL have a timing belt which Skoda UK recommend should be changed at 5 years. The 2.0 TSi engine has a timing chain.

You're misunderstanding the feature - for mirror dip to work the mirror switch MUST be in the position pointing to the passenger side and only the passenger side mirror will dip (to help you see the kerb). As others have said if you don't have the memory option the mirror will dip but when returning will in most cases NOT return to the same position - this is why I tried this feature and then disabled it as adjusting the mirror most times after selecting reverse was a PITA!

Did you have the mirror switch on the drivers door set to the passenger side mirror?

The 'key' is a software code that has to be entered into the infotainment unit, not a physical key.

The official maximum height is 100mm on public roads, but some councils are 'not too careful' and have speed bumps in excess of that - plus in private car parks etc. there is no maximum height limit.

Since the aerial has already been replaced it sounds like the GPS receiver in the Columbus is faulty, I would be pressuring the dealer to replace the glove box unit (which is the 'guts' of the Columbus - the screen is just a screen).

No Skoda UK" = Skoda UK, the importer. Dealers, like Marshalls, should follow the recommendations of the importer - but some choose to regularly try to up-sell.

Haynes have recently said that with sales of printed manuals collapsing all future manuals will be digital only. Haynes to cease publishing new Workshop Manuals

When my cars are out of warranty I always take them to a local VAG specialist or independent - no need to pay dealer prices!

First comment is that they are mounted so low that using them would only be legal in fog to use at other times they need to be at least 500mm high- not what you want I'm guessing? IMHO rectangular lights would look better.

Take a look here

Not sure I'd be 100% sure about that branding...

Where did you get the new thermostat from? Is it a genuine part or a pattern part?

Only Skoda UK recommend such an early change of the cambelt, no other Skoda importer nor the Skoda factory (nor VAG as the engines are used in most VAG marques) recommend a change so early - some VAG documentation even suggests that they are "lifetime"? It's been asked on here many times what makes the UK such a bad environment for cambelts? The conclusion, so far, has been it's Skoda UK doing some covering of their rear end

The 2.0L petrol has a timing chain but the 1.0, 1.4 & 1.5 petrols have a timing belt.

If it's got navigation then it can't be a Bolero! Can't help on the camera, not done the retrofit myself.

That looks like a MIB2 Amundsen to me. To update the maps (which MUST be saved on a genuine Skoda SD card - if you use the one you have then save the contents on your PC first as a backup) then visit the Skoda Portal here then enter your VIN and it will show you the latest available maps to download. Once downloaded follow the instructions to uncompress them then copy all the uncompressed files onto the SD card AFTER clearing it first (I use fast format as that's quicker than deleting all the files).

Drive mode needs an FEC (Feature Enable Code) - if you told the supplier of your hacked unit that you have Drive Mode they SHOULD have activated it. Sounds like whoever hacked your new unit didn't do a thorough job.
