Sorry if this isn't the correct place, but I recently got a Airbag Fault Code: Unknown DTC: 28. Does anyone know if this is related to the airbag in the steering wheel and/or the airbag retaining frame? I have a 2000 Boxster 2.7.

Possible cause of fault

Has the door panel been off for anything recently?

That would make sense. I had the panel off about 2 months ago to replace the window regulator.I guess my next step will be to remove the panel and inspect the connections. Unless you think there are other steps I should take.

Thanks so much for your reply. There isn't any info out there about this error code.
