Im going to say MAF sensor.
Can you log your car with vag com?
or, if your friend has a similar car, use his MAF and see if that works

Lean is never good but your 02 sensor is detecting it and adding fuel accordingly to create a better stoichiometry. I just had this issue recently and came down the the MAF after killing $20 in gas for logging engine data.

You technically shouldn't drive with this but if you must, DON'T go into boost.
