On a Volkswagen, Audi Seat or Skoda vehicle the fault code your likely to see with a fault relating to an EGR valve is 16785 rather than P0104 Exhaust Gas Recirculation Insufficient. This fault code is telling us that the engine ECU has detected the flow of exhaust gases through the valve is too low.

Unscrew the two screws coming into the bottom of the EGR (holding a metal pipe). 6. Unbolt the metal pipe where it connects to the engine and remove. 7. Remove the three bolts which hold the EGR onto the inlet manifold. 8. Unclip the pipe into the EGR. 9. Code 2002. Quote: Originally Posted by Rod_MM.

I haven't taken off anything on this car. As per the other posts and youtube video, you can apparently essentially minimise its function all together with the correct value in VCDS. Basically as close to a delete as possible without physically modifying the car.
