I checked for exhaust leaks,intake leaks,changed front lambdas,changed MAF sensors and still have CEL.
What else can it be...? Error numbers : P0133 & P0153

who did the repair? your cl63 should be under factory warranty..

damn whoever worked on your car kinda stupid .. throwing parts at it..

ECM updates Per Mercedes dealer should fix all your problems..

you didn't answere my question who throw the parts on the car and didn't fix your code..

If you didnt contact your dealer and ask them updates on your car.. go do so..

there's couple emission updates on ecm for CL63 that shouuld fix that code.

I don't know..
ASk your dealer wether Ecm update will overite your powerchip tune..
