Air Mass Secondary Air Implausible

At least that's what my Bav-tech says. The CEL is staying on and I don't want to leave it with the dealer again. Can anyone tell me what the fault tree will tell the technician to do?

have you done a tune to you car ?

if not take it back. if yes. then the tuner can help shut that off.
