Finding the RNS-E before removing the unit

Hi - just PM'd you....

To get the code you'd have to take it to a dealer or use one of the ebay suppliers.
If you're putting the RNS-E back in your car after you've removed it, you "shouldn't" need a code as it should be matched to your VIN.
If you're selling it, then the new owner will need the code.
My dealer didn't charge to retrieve the code for me when my car was in for its last service but don't know if this is true of all dealers.
I've not used the ebay option.
Might be worth sliding the unit out without unplugging to see if there's a sticker or something on top of the unit with the code on...
