After that, in order to get the DINAN tune again, you'll have to have them retune the car on 240E as your previous DINAN tune was on an earlier version and no longer compatible.
For cars under warranty, had anyone had any issues with the dealership when they see that the car has been updated to 240E but don't have any record of performing the software update? It's the automatic tell that the car has been tuned by someone other than a factory authorized dealer. Just curious.
