OK, pilot bearing. Is there damage to the shaft that it supports or guides? It looks like it might be a needle bearing. If its trashed, surface on shaft should be messed up.
I have Z E R O DSG experience. But the damage in your DMF pic's is looking like engine to trans misalignment flexed that plate to failure, cracking. Same damage scenario each time? The splines in the hub, the profile, is is washed out? throwing a burr on the tooth flanks? both dowel sleeves in place? trans dowel holes OK, not shaved and sloppy? Did I say I have Z E R O DSG experience, still true.
Does true complete engine rotation exist in this pilot like a conventional manual trans during release or is the only rotation a back and forth motion as the DMF is allowing a few degrees of movement?
