What is the mysterious BMW OEM "repair kit" for the ASC control unit?

After a week now, I can report that I don't have the symptoms of intermittent speedometer but I do have all three DSC or ASC, ABS, & BRAKE lights lit on my instrument cluster after a period of time after I start the 2002 E39, so it's looking like either the 4 wheel-speed sensors or the ABS module itself.

If it's the ABS module itself, it looks like REALOEM lists it as:
E39 525i ASC hydro unit/control unit/support
01 Hydro unit ASC 34516756341 $2,003.22
02 Repair kit, control unit ASC 34526756343

Do you know what this BMW OEM "repair kit" is? It's not mentioned in the ABS fix DIY which says it can be repaired by these two companies:
1. Module Masters
2. BBA Remanufacturing

So, I ask, what is this BMW OEM repair kit anyway?

Also, do we have self-repair instructions handy (the bimmerfest search button is broken - it constantly reports "connection to failed".
