I connected the Durametric scanner since my airbag light ha been on for a while. (I forget we had one)  I cleared the codes but the light came back on.  The codes shown are:

23 Belt tensioner Driver

25 Belt tensioner Passenger

64 Seat Occupancy Detector Passenger

72 Child Seat Detector


Can anyone provide any info as to what the issue I need to look at?   I've read that the contacts at the buckle and the plug under the seat can oxidize so I will get some cleaner to spray on them.

Porsche produced a TSB for this.

Chances are you have bad grounds under the seats and/or worn/dirty seat belt buckles.


If the TSB (for the grounds) has been done then likely that your buckles are worn out.

Thank you so much!  I'll check that out.  


I hope I didn't err in replying to another post with a similar issue 😯

I've read the TSB and it applies to codes 45, 46, 48, 49.  


It reads there was a production change (8/27/99) for Zuffenhausen production from  WP0...YS620308. My car is 620317.  


Would the codes still be triggered if the latches were not inserted into the buckles?


Thanks, Judi

I had a 2001S made in Finland. It had recurring air bag warning lights and I went through the buckle replace, ground replace TSB sequence and it still came back. Then a master mechanic came up with a new technique (the details of which I was never able to find out) and it was fixed finally.
