Mein Auto: BMW 750i
2011 BMW 750i F01

Hey guys, i had recently posted of a problem with my F01 with several lights on the dash, Abs, brake, steering, engine, lost my power steering, lost speedo, etc. well first i took it to the dealer and for about 140 bucks they told me my DSC Hydro unit was bad, 4800 parts and labor. which i'm going after them for my 140 bucks, cause they diagnose my car wrongfully. Well here it is, the problem was a bad battery, that's right battery. What i found out is these cars now the computer shuts down other unnecessary systems when your battery is going bad in order to allow you to start your car and not be stranded. So i replaced the battery and you must have the battery register to your car, this tells the computer that there is a new battery and the computer then resets all systems and you'll be back up and running. Hope this helps anyone with the same problem.

Thanks for sharing. What's wrong with these German car diagnostics? Had same issues and spend a lot of money with my Porsche 911. Thousands of dollars.
