Great!

 

Thanks, Ralph. Can we determine build week as well?

 

as you know, on you driver side b-pillar is a sticker with the month. if you want to know the build week, your dealership can tell you (they need to look into the file) or your service manager needs to call the audi-rep. they have access to all information such as built-week, export-port, entry port, truck load date, arrival dealership, transport damage etc.<ul><li><a href="http://www.theracestore.com">TheRaceStore</a></li></ul>

 

BZ, okay? As far as the assembly plant number in position 11, seems most of us have a "one" -- was thinking that they really can't assign a letter code as that would denote only one country and the TT is produced in two places, Gyor and Ingolstadt.... think the "one" in position eleven is probably peculiar to the TT because of this.

Thanks for doing this....hope you had a good day at the races.

 

You should add this to the FAQ page!

 

my 2000 180 FWD is

T R U T C 2 8N 4 Y 1 xxxxxx

 

will see that undrway posted a "T" for that position and he is a 2001 FWD Roadster. Hard to keep straight when they change from year to year.

 

yes, the tt is built on two places. most people do not know this. my compliments!

also, just for those who are interested, the A3 (ingolstadt + brazil) as well as the A6 (neckarsulm + china) the only other audis built outside of germany.<ul><li><a href="http://www.theracestore.com">TheRaceStore</a></li></ul>

 

I mean, this is an enthusiast forum!
