Smart 451 airbag ecu - Martin1234 - 02-05-2019

i am having trouble changing vin in a replacement  airbag ecu ,
trw A4518202485  smart 451 2010
i have even tried Avdi  but that cant read the replacement when its on the car because of the vin  being different,
all air bags changed and still steering air bag light on, no errors in das / xentry, and thats with either ecus installed, the original or the replacement,
thanks

try swap eeprom 95320 from old ecu to new one
