Did you try clearing the code and seeing if it reset itself? Also, it seems this code is to do with the turbo and emissions system, so I’d recommend checking your diverter valve and PCV as the PCV is a common issue with the first gen GLAs

I delete the error code and it comes back on the first acceleration, we will review what you told us. Thank you for the information
For sure, glad I can help. If your diverter needs replacing (which I am guessing is the issue, but not certain) turbokits.com and GoFastBits make aftermarket diverters and blow off valves that are more performance-oriented and robust than OEM parts, and are most likely cheaper as well. I am not sure if they are compatible with diesel models though.
