Check the connection to the airflow sensor (on the airbox). If it's OK, then clear the codes and drive it again. That sensor is pretty big bucks, so you won't want to just throw one at it and hope it works. A few other things might be tripping the airflow meter sensor code. Check the vacuum transducers/switchover valves for the EGR and intake butterfly flap and make sure they're good. They won't necessarily throw a code if they're bad, but they'll definitely throw an airflow code if the EGR isn't working at all, or if the intake flap isn't closing when it is told.

Briefly connect straight vacuum to the turbo wastegate, and check your boost gauge. You should get a good amount of boost. Make sure to not overboost too much...I wouldn't trust your engine and turbo to the overboost protection circuit. If you have good performance with straight vacuum to the turbo, your fuel system (including ALDA) is OK.

If everything else tests OK, you're probably going to have to get a new airflow sensor.
