The first seems to suggest that the airflow is lower than expected, it could be a faulty or dirty sensor. The airflow & temp senors are in the doseur / throttle body just after the intercooler. The flow sensor on mine was quite mucky with oil, I cleaned it with brake cleaner IIRC, there are other posts on here about cleaning them so maybe worth a read.
You can check if the boost is ok via the OBD reader with the Torque app or similar.

The second fault code is maybe the glow plug relay, mine has the same fault and I couldn't find anything wrong so I've left it alone. So long as the engine starts & runs ok, I'm not too fussed.
