You can delete the codes through the JB4 itself or a on OBD-II hookup, but you have to know what the codes are, and which ones NOT to delete. For the X1 the full code set has, to my knowledge, not been documented in public yet.

Not quite.
You don't pick and choose which codes to delete, you just press clear codes. This clears even shadow codes. I can confirm this with 100% certainty.
Also, the complete N55 code list is well documented in public and I can confirm they match with the N55 in the X1.
All bets are off for the N20.
