Help Less of Power and Error P0101

Hey Guys,

i've been riding my 156 2.4 20V for about 2 weeks. In the last weeks i registered a less of power. So we create a multiscan-log and read the errors.

After deleting the old errors there were these new codes:

1) P0704 - Clutch Switch
2) P0683 - Preheating ontrol unit (Signal Light is also blinking for a few seconds after starting the engine)
3) P0101 - Air flow meter

It looks like there is not enough Air or not enough pressure. But I don't want to change the air-flow-meter without an skilled help. Is there anybody who can help me?

I attached the multiscan-log.

Greetings, Hans

Changing the afm would require to remove the battery from the car.... once done it's only a small step to replace the airfilter.

Oh an btw, according to your log file the airflow on your car is a little higher than allowed.
Plus the turbo lacks response causing overboost as you lift the gas after accelerating hard.

I'd clean the intake and change the airfilter first to see if things get better.

a clogged intake can have some verry odd side effect.
