I did a deal, a couple of weeks ago, on a car which was built and in transit. The dealer gave me the order number, but said that it may be a couple of days before the tracker picked up that he had released the car to me. It was actually a week before the tracker recognised my order number and confirmed that my car was in transit, stage 5A, en route to Emden. A couple of days later I got an update on the app to say that it was at stage 5B, awaiting a boat. Emailed my dealer and mentioned this, to which he replied that the car was actually in Grimsby, so at stage 6, awaiting a transporter to him! That was last Tuesday, so I’m awaiting the phone call to go see it.
The tracker has always been like this. Let’s just say that it’s a low priority for VW.
Your dealer’s tracker is more reliable. Better to check with him.
