I'm not in VA, but for what it's worth:
Apparently many Leaf techs have wrong info about the part--mine at first said that he was waiting on Nissan to send parts (not true--Nissan sends parts only when the dealer orders them, which happens only when a customer requests the upgrade).
A call to Nissan Support got it straightened out, and after a few days wait for the part to arrive, my TCU was upgraded with same-day service (took it in at lunchtime, got it back after work). This was in Austin, TX.
