S3/RS3/TT Same Rear Diff?

[DeadxDawn]

My 16' S3 has a bad rear diff clutch, and a local wrecker has a complete diff from a 16' S3, or a complete rear diff from a 17'TT.
Not wanting to put another 2016 diff back in, would the 17' TT have the same rear? The wrecker said its part code PYP...

You don't mean diff you mean Haldex clutch which is used to engage the rear diff , but lets not be picky. I would say yes the parts will be the same on the S3 and TT. Are you sure it's not the Haldex pump that is fault and causing the clutch not to function?

I do mean diff, I want to swap the whole unit in, not take it apart for just the clutch assembly.

Its not the pump, and code aligns with clutch failure.
