I have a fiesta 1.4 tdci mk6 on 57 reg
the seats have been changed and the airbag light is constantly on any help on getting it fixed would be great

 

Have you had the fault codes read?

 

Did the old seats have side airbags?
Have the new ones got them?

Did you plug them back in under the seat?

You may have to take the airbags/s out of the old seat/s and fit them in the new seat/s, if the new one/s are no good.
