Well today is the day. They did say i needed to bring all keys with me as they would need to be mapped to the new unit. So it sounds like the thing will be replaced... i dunno if there is a way i can verify that for sure though.

They changed it - that's why they asked you to bring your keys with you.

Cool - Gotta go back in for another tweak tomorrow, as the mileage counter flashes when the engine is running lol, but they have the fix now
