#555 of 678 Check engine light keeps coming on
by brohun

I have a 2007 X5 3.0. My check engine light came on at near 50k miles. The dealer 1st said it was a loose gas cap! the truck has been at the dealer 8 times with no fix yet. They replaced the gas cap, reprogramed the computer a couple of times and now BMW wants to test the gas tank and possible replace! I'm told that there are several other vehicles at my dealer with the same problem! Has anyone else had this problem?? Is there a fix??

My 2001 X5 4.4 light would come on momentarily for no reason. Dealer said while filling the gas, I should have radio turned off. It does not sound intuitive! Dealer also changed the gas cap, the light still turns on momentarily.
While gas price was high a year ago, I started to use regular unleaded 87 gas. The light stays on, until I changed to premium gas 91. I wonder if the light turns on because the octane level was low in the gas?

Since two years ago, my 2001 X5 started to loose columns in the dot matrix display. This includes display in the instrumentation panel, and the radio. A few columns are permanently gone and, a few columns would go on and off. Anyone knows how to resolve the problem?

Thank you. Did you jump start your car before this happened?

Good point. Yes, this happened after I jump start the car. BMW manual had the instructions to prevent high voltage surge during jump by turning on lights and fan. This could be one of the consequences.
One jump also caused my added CD player to fail, another caused my added subwoofer amp to fail. Note that my previous post on the sleep mode 1.2A leakage that started the whole event!
My other thought is that the battery jump position is in the engine compartment, while the battery is in the rear trunk. The large surge current with the inductance of the wiring can cause the high voltage surge. I think the jump hook up should be to the battery in the rear trunk. A design issue!

That's it, but with all the engeneering that BMW has shouldn't the have thought about this potential issue? I heard that there may be a recall for this issue? Does anyone know? .
Regarding the inductance of the long wire to the back is not it, I thought about that and I did the jump right at the battery.
Anyway, if someone had the solution please le us know
Thanks

I have lost all power to the front passenger side door. No power to the door lock, window or outside mirror. The fuses are fine. The dealership took a quick look at it, but didn't find anything obvious. Does anyone have any ideas before I take it back to the dealer for a more thorough and expensive look? Thanks.

I would suggest either bad electrical connections or a defective switch.
