The simplest to try is to tell your dad it's just cool: it's like in the Shadow Edition now.
If that doesn't work, you might want to try populated compatible model forums as well, like these:
- https://www.2addicts.com/forums/forumdisplay.php?f=578;
- https://f30.bimmerpost.com/forums/fo...lay.php?f=429;
- https://f80.bimmerpost.com/forums/fo...play.php?f=631.
Search for your "carly" and the fault code there (using the Search facility in the page top menu) first of all, and/or take the burden of asking them too.
