    EGR Duty Cycle stuck on 99.6 %


    I have a 3.0TDi A6 (2010) CDY engine code and am getting pretty low MPG figures. I ran a VCDS log of Group 003 on my last trip to work and noticed that there constantly seems to be around a 200 mg/str difference between the actual and specified MAF values - actual being consistently higher. In addition, the EGR Duty Cycle does not change from 99.6%.

    No fault codes showing in VCDS.

    Any ideas on other tests I can perform? Thinking something not right with these readings.

    Thank you.
