B6 recaro's in a B7 now AIR BAG light stuck on

[onedumslack]

I just installed some B6 recaros into my A4. I did the bladder swap and everything went well with it. Front passenger airbag turns on and off when someone sits in it and I replaced the passenger footwell fuse with a 30 amp fuse. However whenever the rear seats are plugged in I receive and AIR BAG light on the dash and it's throwing the below code in vag com. From looking this up it appears at least for the front seats this was common issue that if I cut the connectors off for the airbag and replace with butt connectors will fix it. However I didn't see anything for the rear seats although the connectors looks the same. So before I started cutting my rear seat connectors off I wanted to check to see if anyone more experienced in these seats knows if there's another issue I should be looking for. Whenever I plug in my old regular a4 seats the AIR BAG light immediately goes away. Is there possibly any coding changes I need to do since they're B6 seats? Something else in the seat that may be faulty rather than the connector?

You have a 2008. Only year with a different rear seat belt tensionner. Switch tensionners or put the proper resistance to foul the system.

Yeah, you need to swap the middle belt out of your old seat. 05.5-07 B7s get lucky here. It's not terribly difficult, just takes a little time (small hands help).

Damn, handn't anticipated that. Thanks guys.

1 a4 rear seat destroyed while I figured out how not to destroy the recaro. Thanks again. All airbag lights working as they should now.

Edit: there's also another diy for this in addition to the pics link from axis. And you can probably get away without popping off the headrest guide caps and risking breaking them.

I'm curious how to find out the resistance needed and how to make that happen? ie:parts needed
