Check engine

[racebreed]

car went in to vauxhall last week for a service wasnt due for awhile but was getting high oil pressure at high revs up to 5 bar when cold and 4 bar when warm.

Got in it yesterday and it said "service due soon" and then "check engine" "safe mode activated reduced power". i turned it off again and then on and it went away and has not returned? is it out of safe mode again?

any ideas on what it could be? apart from taking it back to vauxhall. They are waiting for a new belt and tensioner and a new drivers seat due to stiching coming out already

well its gonna go in to get sorted i was just wondering if the safe mode continues until its reset or does it reset automatically?
