DS3 injector

[Lakielotz]

Hi, wondering if someone could help! I’m new to these forums so please bear with me.

Had cyl 1 injector replaced in my DS3, it’s been re coded in but now coming up with configuration, the mechanic has followed the coding procedure (driving, getting it to the right revs etc) but yet it’s still saying it’s been unsuccessful. Is there something we are doing wrong?

Thank you for any help

Make sure the correct injector is being coded number 1 is not at cambelt side its the other end
