Just bought this 2003 530ia at 135780 miles.
After driving it at over 80 mph for seventy miles the oil light started flashing, when I came to a stop light the warning oil press low stop engine.
I stopped it took three quarts 5W30 oil. It seem to act ok until, I then drove about five miles, the warning light flicker low oil pressure then flashed stop engine oil pressure low! I checked oil dip stick it was full! I drive it about five miles and oil warming flickers.
It makes no noise at idle or at speed.
After about five miles the warning light starts flickerin, then when I come to a stop it states stop engine low oil pressure.
If I stop it and restart the light does not come back on, until I drive about five miles it starts flickering, then when I stop the stop engine low oil pressure returns! I checked the oil via the dip stick full!
Not sure what is going on! I am going to change the oil level sensor when I change the oil this week!
what is your opinion as to what to check or diagnose on this M54 engine what might cause this issue???
