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.
oh interesting. I hope that isn't the case. A while back I asked my BMW rep about updating to the latest software and he mentioned that after the update, they would re-download or re-program with my DINAN tune. But good question to ask so good point. Thanks!
