Security - if the doors don't auto-lock then when you stop at traffic lights or a road junction then some scrote can open the car doors and steal anything inside the car e.g. shopping, laptop, briefcase, coat with wallet, etc.

Sounds like the HVAC thinks your car is LHD?

IIRC the O2 sensors have a heater, maybe the heater in you O2 sensor is FUBAR?

At the time the engine is built (which is on a separate production line and probably in a different factory which could even be in a different country - my previous Audi was built in Germany but the engine was built in Hungary) it's very unlikely that they would be aware it's destined for a car being shipped to the UK.

Best person to advise is @pab567

Not necessarily, Skoda fitted EFB batteries to many(most?) Octavia 3's with stop/start. Why? They're cheaper than AGM batteries

... and while you're on there download every file about your car (wiring diagrams, repair manual, parts information, etc.) onto your PC.

So it's still not real world, which IMHO makes it little better than the original pre WLTP system.

It's not just Cd that matters but CdA which includes the effective frontal area too - making the vehicle lower and narrower also reduces drag, but wouldn't be popular as too many people like high and wide SUVs now.

If staying OEM is important then several people have updated to a MIB2 Amundsen or Columbus, @pab567is the best person to advise on details and cost.

Wasn't aware that you could have stop/start without battery management??? The only certain way to know if coding is needed is to do a scan with a diagnostic tool (such as VCDS) and if a battery management module shows up (either as a slave of the CAN Gateway at #19 or a stand-alone module at #61) then it needs coding, if neither of those modules exist then there is no BMS and hence nothing to code.

I won't be holding my breath - there are no map updates for the equivalent infotainment systems in VW cars either so it looks like a VAG decision not a Skoda decision.

They didn't have a Battery Management System, so there is nothing to code! AFAIK they didn't have stop/start so didn't need a BMS.

The 20 and A5 mount differently onto the windscreen, so as well as the different camera you need a different windscreen - unless (like some have done) you are happy with a less then 100% secure mounting for the A5.

On the Octavia 3 you need to follow the section titled 19-CAN Gateway using CAN

It's unlikely that the factory will know what discount any customer has negotiated with a dealer - the contract is with the dealer not the importer and certainly not with the factory.

If Halfrauds don't automatically do this simple change then they really shouldn't be fitting batteries to any vehicle with stop/start (AFAIK they all have some form of Battery Management System).

If the battery is the same Ah rating and the same type (EFB or AGM) then it's simply a matter of changing the battery serial number in the BMS module by 1. That's tells the BMS that a new battery is fitted.

Three drivers being spoken to by the stewards for not taking notice of waved yellow flags at the end of Q3. Verstappen passed 2 waved yellow flags which would in normal circumstances mean his lap time would be taken away - but I'm not expecting that to happen in this instance...

Be much easier to help if you tell us what car you have and what model year it is.

That's exactly what happened on my Vauxhall Corsa GSi 16V - the dealer replaced the cambelt but not the tensioner then 2 days later the tensioner failed and 12 of the 16 valves got bent. Fortunately I had taken out the extended warranty so had a new head & valves fitted at no cost to me.

They are in several forums e.g. Octavia 3, Ask A Tech, Diagnostics & VCDS, ....

??? You implied in your previous post that you have access to VCDS ???

A VCDS Auto-Scan will tell you...

There have been many reports on briskoda of the OBDEleven apps making incorrect coding changes - so I think it would be prudent to upgrade to the Pro version and manually make the required changes yourself.
