• Ignition OFF
• Disconnect wiring harness connector from:
  B69 Air Mass Meter
• Ignition ON
• Measure voltage between the following terminals:
  B69 Air Mass Meter
  Wiring harness connector (wiring harness side) terminal 2
  &
  B69 Air Mass Meter
  Wiring harness connector (wiring harness side) terminal 3

NEEDS TO BE GREATER THAN 11v


Then:

Measure voltage between the following terminals:
B69 Air Mass Meter
Wiring harness connector (wiring harness side) terminal 4
&
B69 Air Mass Meter
Wiring harness connector (wiring harness side) terminal 3

GREATER THAN 4.8v

Maf voltage errors are normally just down to them not having the connector fitted properly. Try reseating the connector, I searched this error a while back and this was advised of this and it worked.
