New FRM under warranty, will dealer wipe my DDE tune?
Just found out my FRM is fried and it's covered under the extended warranty. However I've heard that in order to code in the new FRM, they have to re-code the entire car, which will wipe out any engine tunes. Can anyone confirm?

I had to borrow a battery jumper pack from the techs and reflash MHD on the spot (long flash). And lost all the custom coding I did. Spent at least a hr the next day redoing all that too.

However, if your DME has outdated software, or you had the PPK installed by anyone other than BMW, then it WILL be flashed and returned to the latest OEM version. |

Yes, can confirm that the warranty replacement of my FRM module did include a full re-code of the entire car, including DDE. Thankfully the folks at AA Rodriguez were able to re-flash it and have it back to me the next day.
