What is the definition of the codes for a 2006 Mercedes-Benz with P2190 and P2188?

Question

What is the definition of the manufacturer specific codes for a 2006 Mercedes-Benz with P2190 and P2188?

I understand that the second digit in an OBDII code means the code is manufacturer specific. I have a 2006 Mercedes-Benz C230 Sport. It set P2188 and P2190 codes. I am pretty sure they mean rich at idle for banks 1 and 2 respectively, but can\'t find it anywhere to make absolutely sure.

What do these codes mean in a Mercedes-Benz?

Thanks!
