The turbo causes an increase in the compression ratio and the higher octane fuel is needed to prevent detonation or knocking. The engine can typically compensate for this by backing of the spark timing, but this means you lose quite a bit of power and fuel efficiency. I’m in the same boat with a Passat that has the 1.8T engine. Sorry for the bad news.
