W211.006 2007 Airbag coding

Hi all....I'm looking for correct seat mat coding please. It gives me different drop downs. 

Or maybe even code it out? 

Can supply chassis number. 

Thank you

The easiest way is to code it out. Use developer data and find corresponding string, smth written in German "Beifahrer seatmat..." Don't forget to disconnect the plug under the seat.
