How to Check for and Fix the P2015 Engine Error in a Volkswagen

Failure of the intake manifold is indicated by the P2015 fault code for Volkswagens

Your Volkswagen will display the message “Intake Manifold Runner Pos. Sen/Switch Circuit Bank X” if it receives a P2015 code. This message may also refer to anything else that is associated with the intake manifold. For the most part, a faulty intake manifold runner or flap position sensor will be the cause of this engine error. This error message is most often seen on Volkswagen engines with a 2.0-liter TSI or TDI displacement that were manufactured earlier. Because VW’s extended warranty will, in the vast majority of cases, cover this code, the first step that you should do, as recommended by us, is to contact VW or your neighborhood VW dealer to find out whether the problem is covered. If your Volkswagen’s warranty has expired, continue reading for a diagnostic, do-it-yourself repair tips, and a list of replacement components for the P2015 engine code.

What exactly is an intake manifold, and why is having one so vital? The primary function of the intake manifold is to provide clean air to the cylinders of the engine. The air intake, throttle body, and intake manifold work together to filter engine air and distribute it uniformly to the cylinders, where it mixes with the fuel. If your intake manifold is malfunctioning, air isn’t being distributed uniformly to your engine’s cylinders, which may negatively impact performance and efficiency.

If your Volkswagen has a P2015 fault code, are you able to continue driving with it? The quick answer is yes, you can do that the majority of the time; but, doing so is not recommended. While the flap motor arm is caught in the open position, there are circumstances in which the vehicle should not be driven at all, and one of them is when it is in this position. This is a common problem that may result in a significant vacuum leak and subsequent loss of boost or even the appearance of lean fault codes in the car (P0171).

P2015 VW Symptoms

  • The Check Engine Light (also known as the CEL) is on
  • Erratic idle
  • Reduced fuel economy
  • Slight reduction of torque at low RPMs
  • Unusual engine misfires

The reasons behind the Volkswagen engine error code P2015

  • Failure of the sensor that detects the position of the intake manifold flap
  • Carbon deposits may be seen on the runner flaps of the intake manifold
  • Failure of the solenoid that controls the intake manifold runner
  • One of the controls on the intake manifold’s runners has popped off, resulting in a significant loss of vacuum
  • Problems with the wiring of the intake manifold are uncommon
  • Intake manifold itself included a mechanical flaw of some kind

When the P2015 error message appears, the intake manifold is almost certainly shot and has to be replaced entirely. This is due to the fact that the components that make up the intake manifold are not supplied individually, at least not for the 2.0t, and it will be more efficient for you to just replace the manifold itself. You may find a “hack” for the Volkswagen 2.0t TDI engine here, and it is something that you can do to make the engine perform better. Call Volkswagen or your local repair shop and submit your VIN to confirm coverage under the manufacturer’s extended warranty for up to 120k miles.

How to Fix an Engine Displaying the P2015 Error Code on a Volkswagen

We recommend repairing it yourself if the car is not insured, since taking it to a shop for repairs would be rather expensive. On the other hand, if you don’t feel like doing it yourself, you may end up with a cost anywhere from $600 to $1,400. The vast price range is dependant on whether or not you go to a Volkswagen dealership or an independent store.

Injector seals, injectors, and intake runners should all be inspected for carbon buildup before replacing the intake manifold.
