So I'm driving down the freeway cruising about 80mph and out of no where all electronics in vehicle turn off. This last about five seconds. While this is going on, the car remains running. I hit the gas and the vehicle still accelerates. Once all the electronics turn back on, everything seems to be reset. Does anyone have any suggestions what this could have been? The car is a 05 325i in pristine condition.(90k miles) :hmm:

start with bat connection in trunk...pull up on cables to ensure they're tight. Look for corrosion too. Also there's a safety off the + terminal that seems to separate at times.

You'll find all ground locations in Bentley if you have one...maybe spaghettidecoder wds lists locations also...IDK
