Help on a wk140 600s The passenger side air bag light is now on all the time, with or without passenger. Before the light was very inconsistent. What are the next steps?
Thank you for your help

Of course you should have the SRS system scanned for codes with MB scanner.

Yes, well the last scan showed at times a malfunction in the seat wiring. Does the whole seat need to be rewired or replaced? Thank you for your reply

What year car? & what was the code (number)?
