Someone with specialized electronics tools, usually on a "bench" will access the internals of the FRM and code/flash it.


BMW will deny a warranty at one day past 10 years. You could try, but the C__Suckers at dealerships will usually say "happy encouraging talk, give us $150 for diagnostics and we will try and get BMW to cover it". Then screw you .... "yeah we tried as hard as possible but BMW refused- $1200 plus 3 hours, or $1800 total". IMO
