jordi Dear Forum,

I have a question reffered to the passenger cars database (Monitoring of CO2 emissions from passenger cars
1- What does "AA-IVA" mean in the variable "manufacturer harmonised"? Same for "AA-NSS". Are these missing values? and, if they are, can they be considered random or this missings have some particularity in common?
2- What does the variable "Fuel mode" means? possible values are B, E, F, M (and NA which I undersand as missing value)
PS. I am sorry I loss the previous discussion on this same topic (identifying the car model)
