can i register my french plated european renault car in norway

You can register it anywhere that has a legal registration law.

Yes if you have the paper work on it in your name.

You can but u will have to pay the avgift on importation

They have an online calculator, but l warn u that it generally is not cheep!

It is only in Norsk, but enter ur car type - Personbil
The CO2 emissions if u know them or if its a petrol (benzin) or other type
The weight of the vehicle in KG
The engine power in KW or Hk
CO2 in g/km or engine volume in CC
The year of first registration
then a valuation for MVA (VAT)
Then click on Beregn
Hope this helps

Unless it is a veteran car, this will be very expensive.

There used to be special rules if you owned it when you immigrated. They are gone.
