I have recently purchased my 2009 A5 S-line. The engine light just came on, however the car seems to be running perfectly without any seeming issues.
Took the car to mechanic who connected it to the diagnostics and the following codes came up:

P2070 Intake manifold tuning valve bank 1 stuck open
P307A Intake system airflow too low
P0068 Map/Maf throttle position correlation

I did a bit of research and it appears it might be caused due to carbon build up in the hose connected to the air filter or the intake. maybe map/maf sensor needs cleaning/replacement?

No one seems to comment, anyone have any ideas please?
