MAVA need explanation please

Hi,

Could you please explain the "Airflow Offset Drift Code" .................

I have never seen this code on other MB CDI's, (Cars), but have recently had a 2009 Sprinter with OM646 which was throwing that code, and now this week a 2011 Sprinter with OM651 which too has the same code, but both Engines it was very different causes

I have found various articles that suggest there can be a lot of different causes, and my current understanding is all that code is really telling me is that the Airflow from Air intake, through filter, MAF, Turbo, Pipes, Intercooler, Pipes, Butterfly, Intake, Cylinders, Turbo, Exhaust is wrong !!

Common cause is Air Leak, Boost Leak and sometimes EGR Fault, but it can be a whole lot of other things ??

What is your take on this code please ????????????????

TIA,

Cheers Dave
