Hello to all friends, I am writing from Italy to ask for a little help. I have a smart 450 second series 600cc. Fitted with a bosch ecu with code hw 005. Unfortunately during the writing of the flash memory the ecu is dead. I replaced it with one with code hw 004 (smart first series). After coding the key the car starts and it is okay only that the battery light stays on and I noticed that the alternator does not charge the battery. What do you think it could be? I am forced to mount an ecu 005 again? or is the alternator really dead? Thanks a lot to everyone !
