Engine FailSafe Prog

[acattaneo]

I just started my 03 X5 after sitting for the last 6 weeks while I recovered from major back surger and got this message " Engine Failsafe Prog".
It started right up and runs just fine. I turned it off and started it again and got the same message and it still runs fine.
Any comments?
I havent driven it yet because I cant sit in the seat all the way. I just reached in the started it up .
Thanks in advance.

Oh, No F'n way a Ford can beat an X5, its just too ulgy.

I had an engine failsafe prog show up a few weeks ago. Like yours it popped up spontaneously. If you try to drive it you will notice that it starts out in 2nd gear. There is no engine power from a standstill start. The vehicle is in a "limp home" mode. The common causes are usually one of 2 things from the research I have done. Its either a bad brake switch module or a bad harness to the MAF sensor under the hood. If the brake module switch is bad then the computer thinks you are engaging the brake and gas at the same time, so it throws the engine into failsafe so you can't burn up your brakes. Not sure what happens with the harness to the MAF sensor.I "limped" mine into the dealer, and they could not figure out what the cause was. My brake pedal module was fine and my MAF harness was ok as well. The diagnostics isolated the cause between two computer modules. It suggested that there was a wiring short somewhere between the 2 modules in question. My tech pulled the bus between the 2 modules and found no shorts in the harness or in the modules themselves. He put it all back together and cleared the codes, and the problem went away. That was nearly 3 weeks ago and the problem has not resurfaced. When the problem arose it was really raining a lot here and it was very humid. We had flash flooding and I drove my X through water halfway up the wheels several times. My tech speculated that some moisture in the form of condensation got between some pins on the bus triggering the fault. Everything is now dry and my X is working fine.Anyway.....hope that sheds a little light on the issue.I have a 2002 4.4iMark

I had my wife take it out to the store this afternoon and it didnt come up with any errors.
I did wash it and clean the wheels before my surgery and parked it in the garage without driving it. Maybe some moisture was in the brake sensor like you mentioned. Its been very cool here the last couple of months and not driving it after I washed might have left water around the brake sensor?? what ever it is , its cleared itself up . FM (F'ing Magic)
Thanks again for the reply.
Oh, my wife came back with a 3 foot scratch down the drivers side quarter panel from the market...

You should bring to dealership and updated the computer code. The problem code will be deleted.
