Polestar Engineered for my 2018 XC90 T6

[IMAY2023]

Hi guys, I have a big doubt that both me and my brother own 2018 XC90 T6 and he subscribed to orbit and made modifications on polestar. When he did the modification I saw the following options: polestar optimisation, polestar engineered edition, polestar engineered car and polestar car. My brother chose "polestar optimisation", I don't know if this is the option that adds the most power to the engine. Also I am going to subscribe to Orbit and modify it as well, however I have seen people say that for the T6 engine, polestar on Orbit does not add HORSEPOWER, it only changes the shifting of the gearbox. If I want to add hp to the T6 I need to go to a dealer and swipe in the official polestar software. Is this true?

First, check your VIN number here  , it will provide you the info you need. The part number and the optimization #. 
If you go to the dealer, the MRSP is about 1250$ (only software), this price is same as on VIDA if you purchase yourself.  In addition to software price the dealer is charging you for labor too but sometimes dealers do coupons or discounts. The cheapest I heard was around 900$ + labor. 

Polestar is not possible to load yourself via VIDA - Dealership only. 

If you're in the UK it's £555 at the moment and regularly goes down to as little as £300.

I have no idea why the US charge so much for it...

Not accurate, in US you can purchase it yourself and load it to your car as load as you register yourself as independent garage. It appears under software but it costs $1250 paid directly to VOLVO (bookstore).

If you buy it.. you will be refunded a number of hours later. 

Unless you have tried it and can dispel the above it remains accurate as a number of people have tried.

I can, I purchased it for my friend. He had 2019 S60 T6. At that time the dealer in CA wanted $1385 including labor and tax.  I already had the VIDA subscription back in 2023 March He only paid $1250, still using it. I don't know if it has been changed since than.  FYI. polestar software part number was already showing under additional available software TAB. As I said, it all depends, how did you open your VIDA and volvo bookstore account. If you open it as volvo owner. it may be different. My account is independent mechanic. Another point. I had been told by the dealer and VOVLO private service that Pilot Assist can only be installed at the official dealer but I installed it myself after replacing the Hydraulic unit. It automatically showed the pilot assist part number under Hardware changes TAB. It reloads the whole BSM, ABS and the pilot assist with one package.
