Saturday night philosophical question. 

With the new mk4.5 reportedly having 265hp, does anyone know if this is a mechanical difference, or just a tuning remap? If its just tuning, and all the mechanicals are the same as the mk4, in theory if I remapped my mk4 to 265,it shouldn't affect the warranty, as the mechanical components can cope with it. 

Discuss 🤣😂🤣

More bhp but the same 370 Nm.  More magic for the WLTP /RDE2.    If you remap yourd as you see in the warranty t&c,s you are not running factory approved software or hardware.  So invalidate the warranty.   But life is too short. Just do it and if something breaks fix it.

So in theory you could get skoda to upgrade your software to give you 265,then it would be manufacturer approved software? 

That would still be no. That would be Skoda software, but NOT approved for YOUR car.

And no Skoda dealership will ever do that. They are limited by the tools they have and by contracts with country distributor.

No.  In the UK you can not.   There are countries where you get a Remap or Tuning Box that VW approved.   Seat do then or Cupra.   But you can not remap in the UK and keep the manufacturers warranty.      ABT Sportsline.       There were dealers that supposedly did REVO in the UK and said the Warranty was valid.  It was not.  Not the Manufacturers Warranty.

It will probably have the 4th gen EA888 engine with a bigger turbo. As I recall they have moved away from the IHI turbo. So there may be mechanical differences.

Actually i don't think it's the case. VAG is very strict about it now.

There was a time, when in Poland we had a private company that was Seat distributor and they were offering "factory tuning".

But more or less 10 years ago VW/SEAT has ended this deal (in a very nasty way), and they moved Seat distribution to VGP (Volkswagen Group Polska), which belongs 100% to VAG and is now only distributor of all VAG brands in Poland. After this change they of course do not offer this "factory tuning" option.

Might be, that similar setup was used in other countries, but i doubt it's still the case.

There were countries.   I hope that corrects it.
