Hello everyone, someone knows about the airbag control units? Why are there so many different parts numbers of the control units? Mine is probably defective. Now I asked my dealer for the part number which I would need. But the number I was told doesn’t match the number which control unit is now installed in my Laguna. Now I got a used one from a car dealer and the number doesn’t match either. he….the vehicle from which the airbag control unit was built is exactly the same as mine. Year of construction…Key number…kw/ps…usw. Normally I could install this control unit. Or are there other opinions? VG Heiko
