check your sensors 1st,all sensors must be good
if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,
check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,
till you read this you had solve this problem definatly,

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

REPLACE THE POSITIVE BATTERY CABLE.BESURE TO BUY SOME FLEXIBLE WIRE CONDUIT.PROTECT WIRE FROM RUBBING CAUSING SHORT.ALSO REPLACE NEGATIVE BATTERY CABLE.DUE TO YOUR CAR BEING PCM CONTROL BY DISCONNECTING NEGATIVE BATTERY CABLE WILL CAUSE STARTING PROBLEMS AND STEERING PROBLEMS WITH NEWER CARS WITH ELECTRIC POWER STEERING.LET VOLKSWAGON DEALER REPLACE CABLES AND STARTER.

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!
