A dead short on the CAN bus at the diagnostic connector indicates a short on only the Diagnostic CAN, the CAN Gateway acts like a CAN equivalent of an EWthernet switch so a short on the Diagnostic CAN does not necessarliy mean there is a short on any of the other CAN buses in the vehicle (Powertrain CAN, Comfort CAN, Infotainment CAN, etc.)

As previous posts have mentioned, Skoda tune for the lowest emissions rating not for drivability. Drivability has never been the main concern of car manufacturers, 35 years ago when I worked at an automotive consultancy and engine management was relatively new client car manufacturers didn't want drivability just low fuel consumption - the only difference now is they want low emissions.

MY23 refers to cars made from approximately July 2022 (usually after a summer shutdown but not always) with a VIN year digit that indicates 23 as the model year.

I'm speaking for at least me and @langers2k , two of us so that makes it correct to say "we" and not "I".

Then we're unwilling to help you as we don't support owners of clone cables.

For VCDS unless you want to connect to the car using WiFi then go for a HEX-V2 which is USB only, the HEX-NET is USB and WiFi.

When you installed VCDS did you tell it to install legacy drivers? You need those for a HEX-CAN and earlier cables. As Langers2k has said you'll only have limited functionality with a HEX-CAN on a 2023 vehicle (VAG made so many changes in the CAN protocols that the HEX-CAN simply cannot be upgraded to fully work), so you should consider using the Ross-Tech upgrade offer to get a HEX-V2 or HEX-NET.

Probably not applicable to the Mk4.5 facelift, but shows that Euro NCAP share concerns about too many functions being on soft keys not proper buttons. Vehicles need fewer screens and more buttons

The remotes are very sensitive to battery type and age but I do have to ask, since you say the red light doesn't show, whether there is a clear plastic film left on the battery?

What version of VCDS did you have on the old laptop, and the new laptop? And when you purchased VCDS did it come with a CD or not?

The standard spec of Bolero over the years has not included sat nav, until MIB3 it simply wasn't possible to add sat nav to a Bolero you had to swap to an Amundsen or Columbus head unit - so being able to add sat nav to a Bolero (at a cost) is a step forwards.

With all the supply chain problems in recent years, they don't have left over bits at the end of a model run. Remember they've been quietly removing some bits from the standard spec as they couldn't get the parts.

I ran a 2004 Skoda Fabia for 12 years with no visible rust, and a 2006 Audi RS4 for 10 years with no visible rust - massive improvement on several Austin/Morris/Rover/ARG cars that would show visible rust within 18 months.

That's for LHD cars, as you're in Wales you have a RHD car so it should be Mirror control in L

Not software updated, but (at least depending on equipment) the 5F will need recoding to tell it a camera has been installed.

Yes.

On the PFL Octavia 3 (not sure about the FL) you have to cut off a plastic section at the rear of the headlamp to gain access to the indicator bulb. Skoda dealers sell a repair pack that incudes a screw on replacement cover.

Which is why it frustrates me that some on here (not spcdust) quote the infotainment software version number when talking about a different module - it's irrelevant!

Water pump and timing belt on opposite ends of the EA211 engine, so there never has been any need to change both together. New guidance of 140k miles and no time limit for cambelt applies.

Only if the ECU mapping includes timing backoff that takes advantage of the higher octane, I've owned several cars where the use of 97/98/99 made no difference whatsoever to performance, because the ECU mapping did not allow sufficient change in the ignition timing to get any advantage. Agreed.

Whether 97/98/99 gives any performance benefit is down to whether the ECU has mapping to take advantage of the higher octane and lower knock. I've had 4 VAG cars (2x S4, RS4 & O3 L&K) which both benefitted from better performance and better mpg when using 97/98/99 - better mpg by around 5% compared to 95. So in my experience if the criteria is cost then 97/98/99 needs to be no more than 5% more expensive than 95, but if the criteria is performance and the 2.0TSI has mapping for 97/98/99 (my 1.8TSI Octavia 3 definitely does have the mapping so I think likely that the 2.0TSI will) then 97/98/99 would be the choice IMHO. Just my £0.02

I agree, I have the auto-dim mirror in my current Octavia and in my earlier RS4, really missed it in my last Octavia.

Two things to check with VCDS: 1) Is a direct TPMS module being shown in the Installation List? If so remove it from the CAN Gateway coding (unlikely unless the CAN Gateway was also retrofitted at the same time as the infotainment). 2) Check the coding of the infotainment (this is where a direct vs indirect TPMS incorrect coding will cause the option to reset not appear)

I also wonder if the coding of the retrofitted infotainment is incorrect and it's expecting a direct TPMS system not the indirect that nearly every Octavia 3 has - and hence the infotainment isn't showing a TPMS reset button.

A VCDS or OBD11 scan will tell you which ABS sensor is faulty.
