I recently got my XC '19 T5 AWD polestar optimized. I understand that I have to undergo a registration inspection within 30 days of the change. I contacted Bilprovningen and as per them the workshop should have given me a certificate (intyg) mentioning the change. The personnel at Bilia said that the invoice/receipt is sufficient to prove that the optimization has been done.
Do we know who is right here? If there's a certificate, how does it look like?

You need a cirtificate that shows what engine you have and what changes has been done. I did it on my car a few years ago and did get the cirtificate from my dealer ho did the optimization

The invoice won’t be enough. Call them back and ask for proper paperwork on the optimization.

Thank you @Lockis and @V60ccsummum for you replies.
Followed up with the dealer again and they provided a certificate. The registration inspection was approved.

Love the car even more after the optimization.
