Hello , thanks for your question in the autoaid Community.
Your described fault Code means one of the following:
P2004 Hot Film Mass Air Flow Sensor [B2/5] or
P2004 Coolant Temperature Sensor
Look in the actual values for these both Items and look if one of them shows false values
Could you see if the temperature of the engine is correct? Maybe you can see if its false.
But at this engine i had renewed often the air flow sensor.
