Hello , thanks for your question in the autoaid Community.
Your described fault Code means: air mass meter 1 [B2/6], component test
At this fault the air mass could be fault, but often is this a fault it comes from another problem..
Please look at the turbocharger, there is a seal after the air mass and this seal is often oil leaky.
This oil leak leaves down on the intake channel engine and this engines will be flooted with oil.
When this is passed, then comes many faults, one of them is the air mass meter.
I have often renewed the intake channel engine, and the engine wires cleaned from oil, so i know what i say.
Look at the fuses in the engine room, at front left, sometimes there is a fuse burned, because the intake channel engine has a shortcut from the oily part..
