Mercedes S class W220 2004 Model Srs warning issues on dashboard.

Well got my mechanic to read the fault codes and I’ve copied them here:
It’s Not the Child seat sensor fault.but looks like passenger side air bag issues?
Any more advice please
Thanks

Your buckle receptacle is dirty use a qtip soaked in rubbing alcohol to clean the inside of receptacle with the red release button

if that doesn’t do it you’ll need to replace the buckle receptacle unit

These are "STORED" codes, which mean that they happened at some unspecified time in the past (and it could have been years ago), but they are not a current problem. Some codes, such as these, do not automatically cancel, but must be cleared using SDS or a similar diagnostic system. Did your mechanic clear the codes?

Hi
Yes he cleared previous codes mainly due to passenger side seat Matt issue.
This was sorted by him deleting the occupancy Matt from system.
That was 3weeks ago..now the light came back on with these latest codes.
Im told it’s possibly the passenger side bag??
Thanks

An intermittent electrical problem can be a real pain. tusabes made a good suggestion.

Maxmax

UPDATE.... Replaced passenger side air bag ..bought used from ebay.
Got faults cleared..so far all good.
