Yes. We cannot exclude site extension location.
India also had faced similar situation. Refer attachment for your reference.
Now, there is another confusion –
As per your email dated 23 April – the other address is mentioned as site extension location (refer page #2 ). Today, I downloaded the copy of certificate from IATF DB to cross check, the other location is printed as Support location (refer page #2). I attached both certificate copies for your reference.
If the support activities are shifted to manufacturing site, then we can exclude support site. Otherwise, we will have to audit support site. Pl check & confirm.
