    I have EGR issues. This is the fourth time. The VW shop said that the carbon build up in the manifold is what causing the smell in the interior of the car and also the reduced feul milage as well as power reduction.

    Build up of carbon was so great that when starting the engine, the noise mimiked a bag of rocks being moved around. After a week in the shop, the mechanic said there was just build up and there was no way to prevent this from happening again.
