Battery/Alternator issues 2010 528i

I have two issues here My Serpentine belt has worked its way off the Tensioner pulley For the third time in less than a year a local "mechanic" has supposedly replaced the tensioner pulley twice. My belt continues to work it's way off of the pulley. Last night it came off again, however this time. My dash turned on and off the following lights popped up Transmission fail, ABS, Fail, Air bags fail, drive moderately etc etc.... After getting home I shut the vehicle off and it wouldn't crank again. At this point I ran My Carly and received the following codes. 00A559,009CB9,00E714,00951A,00A85F. Anyone have any idea if these two issues are related to one another?

When these cars don't receive the right power level they will throw all types of random codes.

If youíre in the US, go to to find a reputable indie shop that specializes in bimmers in your area. It sounds like your mechanic isnít familiar with bimmers.

Edit: wrong link!
