Immingham Mulberry is where Kia’s national distribution centre and is where the PDI’s take place.
Kia has had issues at Immingham, as it was not excepting any more ships which meant they had to dock at Teeside. This caused extra delays as it took 3 weeks to get the cars transported from Teeside to Immingham. I don’t know if they are experiencing issues but, I guess it could have been missed with all the upheaval.
Just explain to your dealer, its not something you can do as you don’t have the equipment to do it and you want it booking in asap.
When did you order the car?
