It probably just improved things a bit and disguised the symptoms for a while.
I don't see that acquiring the 10 pin switch should be any trouble at all - personally I'd go to TPS myself and order it, as you'll get a better price than the garage will and you can ensure you order it ahead of time so you know it's in your hands.
It may well be on backorder from Germany, but that usually takes less than 3 days to arrive to your local TPS - worst case scenario a week.
If Audi can't order it, it's a generic ZF part in any case I believe.
