THE CAM SHAFT ACTUATOR IS LOCATED IN THE CYLINDER HEAD ON THE FRONT RIGHT HAND SIDE JUST ABOVE THE POWER STEERING PUMP. AFTER YOU REMOVE THE ACTUATOR CHECK TO SEE IF ANY OF THE SCREENS ARE DAMAGED OR MISSING. IF SO REPLACE THE ACTUATOR. ALSO CHECK THE CRANKSHAFT END PLAY. IT SHOULD BE BETWEEN 0.0044" - 0.0153". if excessive crankshaft end play is causing this concern, it will be obviously out of specification by as much as.050" or more when a pry bar is used to move the crankshaft back and forth. IF THIS IS THE CASE AN ENGINE REPLACEMENT IS RECOMMENDED DUE TO THE AMOUNT OF DEBRIS IN THE ENGINE. IF NO EXCESSIVE CRANKSHAFT MOVEMENT NOTICED REPLACE THE CAM ACTUATOR. IT WILL ALSO BE NECESSARY TO DO AN OIL CHANGE.

yoy need to change both the Air Mass Sensor and throttle valve actuator to eliminate this problem. The actuator is pretty pricey but thats the ONLY solution i'm afaraid.

the truth about thse engines is they are hard to work on. if the valve covers are unbolted and still ****, try getting a rectangular peice of wood and putting it on the side of the cover neer the gasget, tap on the other end with a hammmer from all angles to try to break the seal.
this is a common problem with valve covers that havent ever been removed and they heat up, and cool down so many times they practically bake onto the head

First, to read VW codes you will want to get yourself a $50 VAG tool. It will read all your systems, not just the ECU.
Electronic Power Control can go out for several reasons. Check your brake lights with the car running. Check you radiator fluid level. If the car is running bad, you could have bad spark plugs/ wires or ignition coil.
The traction control is tied into the ABS system and often causes problems here as well. Each wheel has a speed sensor and magnet wheel in the hub. You can check these for damage by removing the tires for access. The sensors come out by hand, and inside the hole they come out of is the place to check the magnets with a flash light. Apply a small amount of wheel bearing grease to the sensor.
The control unit goes out in these systems at an alarming rate. They can be easily removed, and repaired for under $200 at modulemaster.com
Since it is intermit, I suspect most likely a loose sensor, or electrical connector.
If your brakes feel squishy at all, bleed the brake lines of air and contaminants.
