I didn't get to finding that module yet, have you or anyone had it out?
It looks like it is on the floor under the console, I havn'y come across any info on how to removal the center console.
Also, I stopped by the local Chrysler dealership today and asked service a question. They answered as I thought they would, I asked if they had a tech that wad qualified and experienced on the Xfire, ha you should have seen the look on his face! The answer was no.
Then I stopped by the MB dealer up the road and met with the service manager. After sharing my tail of woe about the air bag light not going off he smiled and said he really wished he could help but Chrysler used it's own code and that MB diagnostic's can't read our cars, bummer.
