Leaking aft caliper

I did the windback with my own vagcom. Really straight forward. But thanx for the reminder.
I did the isolation procedure to find out where to get the seal set from the "gold smith" (nick name for the local Audi dealer. Same weight to price ratio - hence the name) or from e-bay. Gold smith didn't supply the seal for the input shaft/axle. I'd go for the other if it was the forward side(piston) that leaked. This not being the case I was "forced" to wait for the parts from the UK.
Does anyone know wether the refurbished ones have a new input shaft/axle?
I'll make sure to "confess" when the caliper starts leaking again so that others can learn aswell. (it's not a if but a when)
I hope it will hold up until spring next year - that will buy me some time to figure out a fix that will last a bit longer...
