Is this the emergency cord for the charge port door mechanism or to release the charge cable lock?
I had a problem on delivery where the door wouldn't close. The emergency cord was already loose. Took it to Audi and it was a 2 day repair, the whole charge port had to be replaced. The repair meant audi had to take off the passenger door (UK car), front side panels and wheel. Fairly big job, hopefully whatever the fix its covered by warranty like mine was.
