Depending on how much you drive, the way you drive, and how loud your car is (exhaust, etc.), you may not even notice this has occurred until much later, as was the case with me. The dealer told me that this is true for other similar tunes (I can't substantiate that personally, but ok).

-BMW did charge a small labor fee for removing the DME, but the flash and loaner were all covered. Luckily, the OTA did not lock the DME and it was successfully re-flashed.

-The dealer said that there was no way to disable automatic OTA updates at this time. I wasn't able to get a straight answer to the question, "So you're telling me I could have an OTA forced on me without me knowing and it may overwrite the flash again?".

I believe that you can disable the OTA updates. Go to general settings -> data privacy -> individual selections and turn on/off the ones you want. Included in the list is "Remote Software Updates"
