2001 A4 1.8T 230K, oil light pressure warning light came on, I stopped driving, replaced pressure sender, no change, removed oil pan, cleaned screen, reinstalled, no change, borrowed oil pressure gauge, removed sender to screw in, started engine, plenty of oil pressure, 60PSI cold, rev engine & oil pressure immediately responds, but low oil pressure indicator comes on still, without sender installed, so it seems pressure is not the problem & there is fault in autocheck system, any suggestions on turning low pressure light off?
