This step of keeping the ignition ON is very important. I mean Ignition ON from Cold start.

This is what happened with me.
I turned the Ignition ON and started coding. after a few ones, i started the engine to test them. went for a ride around the neighborhood, returned happily and switched off the engine.

Started coding again. - Mistake.
In 3 minutes or so, my Ignition went off (as per the normal operation of the car)

I was in the middle of the coding!!! i started the ignition ON again but got errors in Error Report of step 15.

I just prayed to all heavens, disconnected the ESys, connected it again and went through the coding steps. i saw that the value was still nicht active, so changed it to activ and completed the remaining steps . thank god, everything went well.

Moral - Ignition needs to be switched ON from Cold start. not the one subsequent to the Engine OFF.

Happy Coding!
