I recently had to jump start my BMW 740i
I recently had to jump start my car. Now, the Gas gauge is acting funny (back and forth and I can hear it click as it goes empty, full, empty, full BLA BLA BLA) and the dashboard gearbox position and mileage screens are OFF.
Paul, I recently had the same issue with my E53 series X5. I found a youtube video which helped me immensely. Try this. https://youtu.be/MUr_eGCJ7wU Chris
