Let me save you the time. I am an insurance agent, and pursued a similar claim for my E92 M3, in CA against Allstate AND Progressive.

CA law doesn't require an insurer to pay a diminished value. If the structure of you car was not damaged etc, you really have no claim whatsoever. You can Google, call, email as much as you want, you're not entitled to it (by CA law), you'll have a hard time proving actual diminished value until you sell the car. Long story, don't lose sleep over it. It happens to us all, it happened to me, you won't get a dime unless there is major structural damage and your vehicle was totaled or something along those lines. Exactly why I leased my new M4, if nothing happens I may buy it but if there's an accident not my problem now.
