That is strange! Seems to be taking an awful long time if it was built over 4 weeks ago! I'm sure you will get a reply soon and hopefully your car is fine. Keep us updated.
I know this is a different car but my brothers RS5 was built first week of October and was at dealer 22nd!
I know saloons are a longer time frame but in your case you could be looking at 5 weeks or even 6! Hopefully not but either way that's abit on the rediculous side.
Just had the following email from my dealer:-
Hi Andrew
Your car is now in the UK at the port in Grimsby. It will be with us within the next 4-5 days. I will contact you as soon as it arrives.
I am a happy boy!
