Historic codes still present but this does not affect anything. ( eg the computer still "thinks" that there are misfiring codes stored etc....no, it doesn't work that way).

I'm sure this is correct but I did have that exact experience. I got bad missfires and limp mode, had all coils and plugs changed, limp mode returned in <50 miles and persisted. Makkan from this forum checked the codes for me and they had not been reset at all. Reset and all has been good for 15k miles.
I'm not saying your wrong and it might just have been a coincidence. Just saying that this happened to me and I'm sure Sam will also remember it (and the rather spirited drive to try and replicate the problem after clearing the codes).
