Not sure what i had or what i have now. I was reading that the factory update is one of the better upgrades as far as reliable power.
This is what the paper from the dealership reads
ISTA/P Version: 48.1.002
Integration level (plant): E89X-08-03-520
Integration level (old) E89x-11-03-511
Integration level (new) E89X-12-07-508
Any able to shed some light on all this? Thanks!
