Here try this solution...You posted P1479. ...When this fault is stored in conjunction with misfire and system lean fault codes check the PCV system and any other possible sources of engine mechanical vacuum leaks. Although PCV failure is most common on the 1.8T engines equipped with the auxiliary vacuum pump, any engine with low vacuum can cause that electric pump to run excessively - resulting in this fault code. Good luck.

This sounds like a "brake light switch" failure in a 5 speed manual transmission car. Please tell me your car has a manual transmission. A scanner, or code resetting tool will not fix this problem. I'm surprised that a dealer would allow this to get out the door without telling you that this car qualifies for a "campaign," or "recall" replacement of the brake light switch under the "N4 program" guidelines. In fact, this program is actually called the "N4 campaign." Good luck.

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.
Good Luck!

First of all you need to get all the code stored in the ECU. It would also benefit us if you do an auto scan that would go through all the different address words of the system not just in address word 01 (Engine Electronics).

Hi,
It is a wiring fault, but they are looking on the wrong end. You will need to have a VW dealer "repin" the electrical connector at the throttle body. What this means is, the dealer will take apart the connector, cut off the old pins and crimp on new ones and reassemble the connector. This is a common problem on drive by wire VW's. The dealer has a bulletin on the problem and I don't know why they missed it. They will probably have to order the connector kit however. Good luck!

I wouldn't trust changing the MAF sensor out first. The make a cleaner that you can spray to clean the MAF. If this gets a little dirt on it, the air flow will be scattered causing the vehicle to ****, shut off, not start, etc. These are very sensitive and it REALLY don't take but your hand about 1 foot away from the air flow of this sensor, and your engine shuts down. Clean it first then go to option B...
