    My friend had an A4 diesel that when under constant, relatively urgent acceleration goes into limp mode. It is a sporadic fault, although happening more constantly, but never happens when you floor it to overtake.

    Does anyone have any ideas? The local stealers can't find anything, and there is no error codes being thrown up.

    Someone in work has suggested post cat lambda sensor, but i thought I'd ask the experts!

    Cheers
