ECUs from that era are coded to the original vehicle they left the factory on. Ideally, if doing an ECU swap you'd need the ECU, key, ignition barrel, steering lock & maybe another couple of bits.

An MB independent specialist would be aware of the coding & associated issues.

Hi mate,thanks for reading.i have replaced the ecu,key, ignition barrel,and steering lock,but he still can't get the airbag light to go off with his diagnosis tool

Is it a Mercedes Star diagnosis tool?

Airbag systems are quite complex. In addition to the drivers steering wheel airbag and passenger airbag there may be other sensors and other airbag units to be taken into account. Things such as seat occupancy sensors and curtain/pillar/knee airbags. The car the ECU originated from may have had these additional units and the system in your car is now registering them as faulty/missing. As Neilrr has said the codes on Star may help

Just wanted to say mate he isn't a mercedes specialist so maybe it's not, maybe if I speak to a mercedes specialist they may be able to help me
