14 GT3 19K miles , oil level shows max level exceeded safe to drive , last time drove had 3 bar above min. no oil has been added , anyone have issue with this

 

Common issue. Drive harder (including launch control), Open rear deck lid for couple minutes, Open Oil Filler lid (not with engine running) seem to be common fixes.

If none do it, you can siphon a bit of oil from filler or loosen oil filter and let some spill out under the car and re-tighen filter (20NM or 15 ft-lbs).

 

That oil measurement is about as picky as some folks are about their 'preferred pronoun'.
