If you look back at this thread to PG220’s helpful post on September 18 you will see he has detailed all the progress codes on the Audi production system which your dealer can access.
Ordering in early May and knowing it was a likely mid October delivery, I asked my dealer to email me a copy of the system update in August. He did and it was code 10, showing provisional build week 37 and shipping through Grimsby. This proved correct. So the Audi system was accurate.
In my experience of ordering a factory build car over the years, dealers can be reluctant to give one this type of information. But if you are persistent and ask for it specifically they should let you see a copy of the manufacturer’s system output.
I was careful not to pester the dealer for information too often and knowing the build week was mid September waited until later in September to ask for another copy of Audi’s system output, this showed code 38 - the car had reached Emden.
When he asked me to sign the finance agreement last week I asked again and this time he told me that the car was at Grimsby waiting for a transporter to take it to the dealer’s prep centre so I didn’t need to see the system output.
In my case (so long as the car turns up soon!) the Audi order system has been accurate and helpful.
