I can't help with the codes but when my ESP/BAS played the light kept coming on it was the brake switch , in england it cost £10.00 and you can fit it yourself .Go the my site for all the information
I can understand you well so hopefully my site will help you solve the problem,
MB will want you tyo keep going back all the time you can pay, if they charge you to cure the fault and it come back take the car back and tell them you paid them to have the fault cleared and your not happy You should not have to keep paying for the same job .
The diagnostics at 100 should have told them what was wrong with the car so why haven't they fixed it for good.
