Engine Fail Safe Mode Questions

[Cangelo629]

Looking for Advice :) Was Driving Yesterday About 2 Hours At 65 To 75 Miles In Heavy Rain With Wipers Air And Xeon Lights On I Was Coming Down A Steep Grade And All Of A Sudden I Picked Up A Engine Fail Safe Program And I Also Picked Up The Yellow Service Engine Soon Light Car Just rolled Past 67,200 As This Happened When The Light Came On I Lost No Power No Funny Noises Shimmys And All The Car Functions Were Working Properly. Well I Was Stuck Anyway As I Was In A Construction Zone Miles And Miles Long So No Where To Pull Off. Finally I Pulled Over Turned The Car Off Waited A Few Minutes And Then Started The Car Still Had The Fail Safe Mode Again No Noticible Issues So I Continued Driving Just Keeping The Tac At 2grams Or Less Had No Problems With Engine Power If I Needed It And Continued On For Another 45 Minutes To My Destination. I Pulled In Waited 10 Min Or So Turned The Key The Fasten Seat Warning Came Up First Then Fail Safe (I May Of Still Had My Seatbelt Attached The First Time I Tried This Back Up On The Turnpike.) Let The Car Sit Came Back Late 9 Hours Later Turned The Key No Warning And No Service Engine Soon Light, All Was Good.:clap On A Hunch And I Cannot Tell You Why Started To Look At The 2 Selonoids Or Sensors (Guessing They Are) Attached To The Oil Filter Housing Behind The Driver Side Headlamp. One Is On The Top The Other Attached On The Bottom They Are Attached With A Rubber Dampers Hanging Off The Side. Well Bingo All Of A Sudden I Started To Hear A Flutter Clicking Sound:help Sure Enough Had A Engine Fail Safe Mode Still No Service Engine Light I Flicked With My Finger It Fluttered Louder So I Turned The Car Off Waited Turned It Back On Warning Was Gone. The Fail Safe Warning Showed Up Today Intermittently Early On The Way Home Then Just Disapeared. We Stopped Evry 30 to 40 miles A Couple Of Times For Some Site Seeing The Car Started Everytime With No Warning Lights And Again All Funtions Of The Car Appeared Normal, No Loss Of Power Mechanicaly Or Electrically As Best As I Can Tell. Eventully It Just Disapeared 250 Miles Later No Warning Lights All Seems Ok But I Know It's Not. Question ? Is The Fault Stored In The Car And Does Anybody Know What The Sensors/ Selonoids Might Be? It Is Obvious I Need To Have Them Check Out And Replaced But what Would Cause Them To Do That. I Did Try To Check On Reolm But Just Located Generic Sensors And Selonoides. Any Help Is Appreciated.Thanks Carmen 01 740iL 67,465 miles And Quiet For Now :think:
