I na previous post I mentioned that after getting the X5 Detailed, all kinds of warning and Failsafes popped up then wouldnt start. After sitting for a few hours, all was fine.....until 2 days ago.
I was driving and all of a sudden my Radar Detector starting flashing "Low Voltage". Thought that was weird so unplugged and replugged. Same thing. Switch to plug in rear seat, same thing. I started wondering if the warnings were going to rear its ugly head again. All was fine for about 20 more minutes, then..."DING" Radio/Nav went black, Transfailsafe, Engine Failsafe, DSC, 4X4, Low Tire Warning, all popped up and truck went into limp mode. I crawled back home. About 10 minutes later on my way back, Radio popped back on and Failsafes were gone. Pulled in the driveway and turned off X. Restarted and all was fine except Headlight indicator flashing, and the 4X4 warning light indicator. Next morning all was well.
Anyone ever experience this????????

Had something very similar with another car. In that case it turned out to be weak battery contacts, only showed up when the car was warm; so I would check those first.

Play it safe and take it in for diagnosis. That warning can mean a number of things...some can lead to bigger issues.

My edumacated guess would be the battery or alternator need to be replaced.

It looks to me like the alternator output harness is loose......

Did you clean the engine bay? did you clean it with the engine running? could be that you fcuked up your alternator
