Volkswagen and Audi models have a tendency to give drivers a P2004 or P2015 error, which is basically a “Flapper Sensor Failure” code.

If this error appears, chances are it's the Variable Intake Manifold Adjusting Unit. Volkswagen models have a Variable Intake Manifold that is simply brilliant. The variable intake manifold features a flap system governed by the engine control unit that meets both those demands, channeling the air via the long intake manifold at low revs and through the short section at high revs. Yet, like most things, there are areas that will break, but Euromotiv has the part you'll need to fix that right up.

Direct from VAG, this new adjusting unit will have your car performing like new again.
