Emissions failed again

Hi,

I have a ML230 European and 6 Emissions -Failed this year.
I already change O2 sensor, catalytic converter, spark plugs and MAF.
I spend much money replacing the components and for what?
I already send the car to mercedes and no one can tell me what the problem is

6 Emissions -Failed

IDLE
Co = 1,13 must be <0,5%

3000RPM
Lambda close to the limit = 1,03

Could you help me please?
Thank you in advance
