Gearbox 01E Differences S2 S4

[Christoph]

Hello

What is the difference between the drive shafts in the gearbox of the Audi S2 and Audi 100 S4?
Part numbers would be:
01E311105H
01E311105J

Thanks for your Help

Well looking at the part numbers, they're the same part only the one ending in J is a newer revision.

VAG uses an X at the end to denote a refurbished part.

In the 01E boxes all these main input shafts the same other than the later a4 01E boxes?
As in narrow, wide, flex narrow and fel wide
they all interchangable.
I wasn't sure if bearings or the cut gear was different.
