Hi folks,

hoping someone here can help me understand. I’ve contacted service waiting for them to pick up the car. It appears then goes away.

48v vehicle?
Several 48v system connection issues and I’ve seen a few alternators as well.

Its not a 45e its the gas 4.0.
Thanks for your replies.
My guess then is either your battery faulty or the alternator is wonky, or there is a loose wiring harness. EdIt...forgot about the mild hybrid setup. Dang these cars are complicated.

Is it a 48v? ( do you have a big purple wire in your engine compartment? )
I hope this thread gets updated with the result. 2 guesses, Alternator or Drive belt issue where oil has gotten onto it via the crank seal or intake pipe leaking

i will update this forum 100%. I am having it picked up for service on Monday.

i dont think i have the 48v. I have the x5 xdrive40i, msport runs on gas. Apologize for any misinformation.

i actually love the car, its my third bmw, had the time to custom build this one with M sport, shadowline trim, air suspension.

whats weird is this error appears for 1 day and only when I accelerate quickly and let go of the gas pedal. Then the warning disappears.

Thanks for keeping us updated. What year is yours? Starting with MY21 the 40is got the 48v mild-hybrid system.
