  1. DPF Blocked value constantly at 0.0%

    Alfa 159, Brera & 946 Spider
    Since i bought my car ive been keeping an eye on the DPF, as far as I know the last 12,000 miles ive done it hasnt done a regen. The blocked value on MES is always showing as 0.0% does this suggest a faulty sensor, the DPF is regenerating too often or possibly the DPF has been modified in some way?
