What Causes the P2015 Code in a 2015 VW Tiguan?

Several factors can trigger the P2015 code. These range from simple issues like a loose connection or faulty wiring to more complex problems within the intake manifold itself. Carbon buildup, a common problem in direct-injection engines like the one in your Tiguan, can restrict the movement of the intake manifold runner flaps, leading to the P2015 code. Other potential culprits include a malfunctioning sensor or a faulty actuator motor.

“In my experience, carbon buildup is often the primary suspect with the P2015 code in these Tiguans,” says seasoned automotive technician, Paul Sanchez. “A thorough cleaning of the intake manifold can often resolve the issue.”
