a lot of codes there, airbag it seems you didn't follow procedures and pictures to show you how,
other codes could be bogus stored codes and need clearing,
ABS and you hammered the bearing in? that's not good practice ( did you remove the ABS sensor intact and the ring gear ) most have a cog/gear type fitting and toothed so if you damaged that the ABS and any other system linked to it will fail ( 00283 speed sensor or front left g47 ) and the unit will need replacing
