W203 C220CDI
W203 SRS issue
Hello,
I'm having some issues with my recently bought w203 c220cdi my01.
I've got fault codes of my both rear side (door) airbags.
B103B - R12/12 rear side airbag squib resistance is too high
and
B1039 R12/11 rear side airbag squib resistance is too high
The thing is that my car doesn't even have rear door airbags installed so I'm out of clues here. Although I have two theories.
1. Programming issue (I wonder if the car can lose original coding). So fix in this case would be reprogramming rear airbags as not installed.
2. Issues with the SRS control unit.
I don't know how the wiring is done when there are no rear airbags installed so I wonder if there are just some wire loops somewhere in the car or is it just a matter of coding.
