i8 Activation HV system after accident

Hello Who can help me? I bought an i8 accident car and rebuilt it so far.Now I have a huge problem. In the accident, the crash sensors took the HV system completely out of operation. In level 2 , where the entire system is switched off and can only be unlocked again with special software and codes. So here it is not about that only the unlock plug is locked again. I then had the vehicle with a The BMW dealer, who, however, failed in the unlocking and did not want to continue. Who is able to help me? I live in Nuremberg and I like to take the car where I am helped and of course also pay generously for the help. I also like to bring the car abroad, the main thing is someone who can help me. I can’t manage to sell the repaired car. Please call me either 0179 8100090 or write to me by e-mail [email protected] I hope I can find a specialist who can help me and make the vehicle run
