FL Audi S8 left side hub part no.

[SilverS8]

Good evening.

I need a new hub since the aluminium that clamps one of the control arms are broken off and not sure it will last another year(so far so good)

But when checking ETKA there are several different hubs for the facelift and i can find the one i need. ( I have Brembo's)

The choices are

4D0 407 257 K (etka says for model PR-1LT?)
4D0 407 253 (Erka here says its for 6-8 cyl but no mention of S8)
4D0 407 257 AD (For cars with 20" wheels) so prob not this one


I have sourced a used one that seller claims is the correct for my S8.
Part no is 4D0 407 257 0. Other no's he found on it was
A.S 2.1
+GF + HE
K1373

Appreciate any help
