HOW TO FIND RPO NUMBER

[muresan504]

I have a Citroën c3 from 2002 and the car does not have that sticker where it says the RPO code and the color code, etc. I need the rpo code and I don't know how to find it.

Thx!
I have another question, what amount of air conditioning refrigerant must be added to the installation for this model? The service guy put 500 grams in my system. The air conditioning compressor is new, the radiator is new, the cooling fan runs on both speeds but the air conditioning compressor starts and after a few seconds it stops then starts again and stops, I thought maybe it is not the correct amount of added agent
