A4 B7 Wheel Security Stud Key

[Dindiesel]

Hello everybody,
I have an A4 B7 from 2007.
the tyre fitter seems to have fancied my wheel security stud key, and kept it. (yes i know, i shudda changed for studs years ago......long fingers n all that.)
i bought a set on ebay, but while it fits, its a poor fit and soft quality and is slipping now.
I took said key to audi to order one.
of course NOOOOO, CANTTTT, WONTTT featured alot.
i said could you show me the box od master keys and ill select the one to order, (£50).
They want me to bring in the car (130 mile journey). Not sure they understood the lack of the third wheel!
If i post a pic does anybody know how i could odtain the fabled part number?
Thanks in advance.
Din.

Is there a number or letter on the one you have that fits? That should lead to a part number. For example 4F0698139C 801 is "A" in one of the ranges from that era through to ... 820 being "X" (with I, K, O and U left out).
