The disqualification from the first race in Skellefteå earlier this year came after a protest from the Lestrup Racing Team when his car was too low at the post-check.
PWR Racing argued that it was due to an injury during the race, something the Disciplinary Committee disagreed with.
But now the Swedish Motorsport Association's legal committee has decided that Dahlgren will get the victory back as he was never heard by the disciplinary committee during the investigation.
The disciplinary committee will conduct a new investigation during this weekend's final, which means that the conditions can change again.
Currently, Roberg Dahlgren leads with a total of 47 points over Andreas Bäckman instead of 24. In the final there are 65 points left to overtake.
