Does “Restore OEM” wipe a dealer-installed Polestar Engineered Optimization? - bubinatar - 08-02-2026
Hi all,
I’m about to buy an OrBit subscription, but there’s one thing I need to clear up first, because it could be an expensive mistake for me.
Background: I bought a used S60 (3rd gen,).After buying it I had the Polestar Engineered Optimization installed at the Volvo dealer — the official paid one, not a config activation. It cost real money, so losing it is not an option.
My question: if I use OrBit to change some settings and then hit Restore OEM before a dealer service visit, does the dealer-installed Polestar optimization survive that reset?
What makes me unsure is that OrBit itself exposes “Polestar optimisation” as a config item, and as I understand it Restore OEM doesn’t write back a per-car backup — it restores the standard OEM config logic. So if any part of the Polestar activation lives in that config layer rather than purely in the ECM/TCM software, I assume a reset could switch it off. Is that correct, or is the dealer version a genuine ECM/TCM reflash that Restore OEM never touches?

Polestar is your OEM configuration.
You'll be fine with restore
