Two different S6 Avus Wheels?

[Leeds]

My S6 Avus wheels are 7 1/2x16, et37, and I've been offered a set that are
7x16, et40. Does anyone know if Audi had two different spec S6 Avus wheels,
and whether they line up in the wheel well the same? My current ones are on
my 200q, and I'd want to use these for same.

TIA,
Kerry

P.S. Still haven't heard from the lister with the NOS A/C programmer, so I'm
getting ready to buy a new one and let inquiring minds know if that solves
the weird A/C symptoms.
