I just got my car back from the BMW dealer after they did the 50% off Dinan ECU tune. I plugged my laptop with ISTA+ to the car and it shows I have I-Level E89X-16-03-502. Does this mean I'm still on the DME 240E or later engine software? Or is the I-Level irrelevant after a DME flash tune?
I've never used INPA, but I do have it loaded on my laptop. Is that the only way to read what the actual DME software is? Still learning...
