Whoaa - does the dealership say the modules were not wrecked in the accident, or the insurance company?

If you can honestly say all was well before the accident - sue the insurance company! You paid them to insure against damages of an accident, now they have to pay! I hope you did not sign any releases with them. In either case, consult a lwayer specializing in this type of scam.
