Besides using digital manometer to properly test the vacuum level, also look at your oil level the sump. We find a lot of cars simply have too much oil in them, which creates this problem, and also significantly shortens AOS life expectancy. On your digital oil level display, your oil level needs to be at least two bars down from the max level; Porsche released a TSB on lower oil levels in these cars several years ago, and even released updated dipsticks for the cars that actually had one, that also moved the full level downward.
