*need help with low oil pressure light
I have an 05 545i 6spd man...with 91600mi.... been running great...had a rt bank emissions light come on...but flushed out vacum lines with seafoam...all good
well now changed oil with recommended amsoil and mann filter...been using amsoil for yrs in other cars...low oil light is coming on and going off...anything below 2200 rpm casual city driving...no light...freeway driving and medium acceleration and light comes on and goes off....
Replaced oil pressure switch $12. ...no change....replaced 6 oil check valves...found mechanic bulletin on possible failure. ..all looked good but replaced anyway cause of bulletin. ..$140...preventive maintenance. ...mann filter and oe filter are different. ..so I replaced with oe filter
Still have light coming on and goin off at 3 k rpm...not enjoying this wonderful car at the moment. ...please help?!
