Hi all can any one help

I have got a 530 diesel & I tried to reflash engine ecu after fitting new air mass (with bmw kit from BBA) now the cars a non runner (bba cannot help)

ecu crashed half way through the up grade. I have tried again and again but I am not sure which part numbers to enter to start a reprogame as it asks for the basic no four time s?. I did use a battery support and I did read the TIS. I am using bmw programman sss

Thanks


any advice would be useful
thank you james
