Is this most likely down to a faulty maf?

Can' tell from that I'm afraid as I don't have a Lexia that works, what does it do or doesn't?

That code is usually for a faulty MAF or the wiring.

Take out the air box and MAF and check the wiring from the MAF socket right down to the loom.

You can check inside the MAF for any broken wires, but its not a conclusive test.

Thanks for the reply guys I cleared the codes last month and have done another scan today and the following faults have appeared in this order.
Permanent fault. Air flowmeter signal. Air flow too low coherence P101.

Intermittent fault. EGR air circuit fault. Airflow measured less than reccomended P0401
