You guys aren't mentioning where in the world you are :-)
But almost in all cases if you do anything unofficially to your car, you will void the warranty. Polestar is the only software upgrade you can do that won't affect your warranty. If you are lucky and stay in Germany (and maybe 1 or 2 other close by countries), Heico is approved by Volvo there, but nowhere else.
On the other hand, you can do to your Volvo whatever you want, loose your warranty, and Volvo won't mind, as they don't have to fix your car on their account, as you have to pay for the bill, so in fact they score and still smile.
