2011 F25 "To flash or not to flash, that is the question"
I have a 2011 F25 X3 35i with these options:
Premium, Technology, Convenience, Cold Weather & Dynamic Handling packages, HUD, Premium Sound, SAT radio
The I-step is F025 10-12-503 for all three steps so I assume it has never been updated since built. There is nothing wrong, everything is working. I coded the sport display (HP/Torque) hoping to use that feature, but I never got it to display, so I don't know if flashing the CIC would enable the sport display or not. I don't want to upgrade just to upgrade since there is some risk involved, but if the newer firmware has some improvement, I'd be interested in upgrading all applicable modules. Maybe the sport display will work with the upgrade? The vehicle production date is 2011-02-10 so with an I-step of 10-12-503, it's pretty old. Any advise is appreciated.
I looked through some of the flash procedures using e-sys and it looks doable.
I'm up to date on for the software I downloaded from BMW for:
> MX-3.5.4, TX-3.5.8
> TX-2.6.6
> MX-1.12.0
