This is why I said "on the pump" (etched 8E0 614 111 T). There's also the piece connecting to pump (Bosch sticker with a barcode), and the under dash piece (also a sticker 4D0 907 389 E).
Matt tells me again, that since I have a module under the dash, that I have 5.0. According to everyone here, since I have ESP, I have 5.3.
Directly from Matt:
[The part connected to the pump is just the solenoid pack - there's not really much to it. The control module portion is what's under the dash. The 5.3 units actually have the control module bolted directly to the ABS pump whereas you just have the solenoid pack.
Thanks,

I just sent Matt the photo I posted here; we'll see what he says.
I emailed Shokan (they have a 8E0 614 111 T pump in stock) and asked them for the part number on the black part (they call it a module, and I have THE EXACT SAME PUMP). I'm expecting to see something like
0 273 004 ??? (the last 3 digits are the key according to Modulemaster and cheap ABS).
Module master has a link to Bosch 5.3 with ESP...not repairable:
