Was this car in an accident?

Did you replace those parts mentioned in the fault codes?

 

I have a 2006 bmw 325i simil codes

Hello everyone I have the following codes and yes the car was involve on an accident not major but I really don't know what was replaced other than the front end parts.

codes.

93B4 DRIVER`S AIRBAG, STAGE 2

93B2 SAFETY BATTERY TERMINAL

93A9 BELT TENSIONER DRIVER

93A8 DRIVERS AIRBAG STAGE 1

93B6 TENSIONER REAR RIGHT

93B5 TENSIONER REAR LEFT

I CHECKED THE BATTERY TERMINAL AND looks ok, if was deployed and don't look like it was, airbargs ar eintact I can see the front en damage all was replaced is the bumber and the metal cross member behind the bumper. headlight wer elittle damaged so I put new ones, so any help will be greatly appreciate it.

 

If the accident was bad enough to replace the cross member, the airbags should have fired. They probably do have some form of fault. And which battery terminal did you check? The ones in the trunk, or the positive terminal under the hood on the driver's side?

 

I cecked the terminal on the trunck and the little ignigter on the positive terminal did not deployed.

 

There is another positive terminal on the front, near the strut brace on the driver's side
