I did think the air flow meter, I've read a guide on another site that tells you how to clean them, could be worth a shot?
I think it was the pre-cat they changed, it was done as part of the service. Everytime it was plugged in it said lambda sensor, then the last time it said IMRC. Its not been a major headache just the light will stay off for months then be on a few days but the runnings not affected.
