I need some help. I already have changed the battery and the alternator. thats what the dealer recommended. Still the same issue keeps coming up . After the car sits for awhile it drives again for some distance maybe a couple to few miles and same issue comes shows up . Looses power and the display says reduced power the throttle doesn’t respond well and all the lights show up in the dash like it’s Christmas It’s 09 X5 4.8. I believe the voltage regulator was built in on the alternator so I was told. Any ideas??

So I read the thread on this issue and went with changing the throttle body and the harness. (Had to cut and tie the new one) . Drove it around for a 3 hours and so far it is still working ok . I will keep you posted later with any other news.. thanks ard
