Hello,

my E91 2007. 325d was involved in an crash and the seat belt tensioners were deployed and the BST on the Battery to.
I didnt swap them after the repair just let them code out so i dont get the warning show until i replace them to. The BSt was "put" together and the little black wire disconnected.

I changed then the seat belt tensioners on the drivers side and the two in the back. Now i get again the "Restrain System warning" and the airbag light on.

Do i have to code the new tensioners or is the BST cable now the problem? I tested the belt tensioners and all of them showed 0.4-0.5 Ohm resistance witch should be ok as far as i could google out.

You need to code them back on if you coded them off prior to replacement, and clear codes after

I got into a crash. I replaced my seat belt tensioner. No coding needed. I did have to clear the fault codes.
