Audi A4 8EC Readiness Code

Hi guys! I have an Audi A4 8EC BFB engine code with fault codes P0507, P1171, P1297, i checked everything for leaks, i test a used throttle valve but faults come again after one week. I bypass the wiring of the throttle with new cables and when i try to make the readiness code P1112 system too rich code appear. I changed the MAF sensor after some other checks and the code done correctly in the guided fault finding. My problem is now when i read the readiness from the self-diagnosis the second digit is 1 (01000000) and i don't know what that means. Does anybody knows i make the settings 3 times and all the systems are ok.
Thank you.
Regards
