P2015 Code: What It Is And How to Fix It (2024)

Modern technology and engineering have brought substantial improvements to many of the basic components commonly found on cars and trucks. Almost all of these advancements are done in the name of increased performance, improved fuel efficiency, and decreasing vehicle emissions. Long gone are the days of basic intake manifolds. Today, many vehicles are equipped with variable geometry air intake manifolds. These manifolds are adjusted by the Powertrain Control Module (PCM) to meet various driving conditions. One common issue reported by Volkswagen owners from 2006 to 2016 involves the P2015 error code, which revolves around a problem with the car's intake manifold. In this article, we are going to cover exactly what this code means, how much it costs to fix, and how to fix it.

What Does The P2015 Error Code Mean?

For many years, manufacturers had to choose between long-runner and short-runner air intake manifold runner lengths. Starting in the 1990s and 2000s, manufacturers such as BMW, Toyota, and Volkswagen began designing variable length intakes. These intake manifolds are capable of altering the runner length during different driving scenarios to increase engine power and fuel economy. Variable geometry manifolds use an electronic or vacuum operated actuator that is connected to the runner flap linkage to control the direction and flow rate of the intake manifold. In the case of the P2015 error code, the PCM detected a fault within the air flow control unit of the intake manifold. This code is specifically set by the PCM when the desired position or flow of the intake manifold flap cannot be achieved.

What Causes The P2015 Code?

The P2015 fault code is most commonly caused by one or more of the following:

• A faulty control actuator
• A clogged or restricted actuator vacuum hose
• Stuck or binding intake flap
• Faulty intake manifold

What Are the Symptoms of Code P2015?

The following are the most common symptoms reported with a P2015 error code:

• Illuminated check engine light
• Failed emissions test
• Decreased engine performance
• Decrease in fuel efficiency
• A rough or erratic idle

Can I Still Drive With The P2015 Error Code Present?

In the case of the P2015 error code, the most notable symptom reported by vehicle drivers is an illuminated check engine light. This means driving with the P2015 fault code will be okay. However, your vehicle will expel increased vehicle emissions. If the vehicle is driven for a prolonged period of time with the fault present, more serious symptoms may become noticeable. We recommend fixing the P2015 fault when possible due to the increased emissions.

How To Fix The P2015 Error Code

When it comes to repairing the P2015 code on a VW or other brand, we recommend confirming the Diagnostic Trouble Code (DTC) is active before attempting any repairs. To confirm the code is still present and active, you’ll need your vehicle's computer scanned. System scans are commonly performed by auto parts stores for free. Repair facilities, dealerships, and emissions testing facilities can also perform system scans which may come with a ‘diagnostic charge’. Once your vehicle’s computer system has been scanned and the P2015 fault code has been confirmed, you can begin your diagnosis.

VW released multiple Technical Service Bulletins (TSBs) in an effort to address the P2015 error code, which contains suggested repairs.

The following are the common repairs for remedying the P2015 error code.

Torn, Missing, Or Clogged Actuator Vacuum Hose

The intake manifold flap(s) are controlled by a flow actuator. The flow actuator uses the engine vacuum to modulate the position of the intake flap. A damaged, clogged, or missing vacuum hose could be the cause of this error code as it would not allow the actuator to function. Inspect the hose for proper connections from the intake manifold to the actuator body. If the hose is missing or not properly connected, replace it. If the hose is properly connected, we recommend removing it to further inspect it for blockages that could require cleaning. To clean the hose, remove it and gently blow compressed air through it.

Faulty Air Flow Control Actuator

If you’ve ruled out the vacuum line as the cause of the P2015 code, we recommend turning your attention to the control valve. The air control actuator/solenoid can fail and could inhibit the actuator from controlling the flaps. You can replace the air control solenoid with basic hand tools.

Replace Faulty Intake Manifold

The air control flaps can bind over time due to carbon, debris, and wear. Some companies offer replacement control flaps, but it’s usually recommended to replace the intake manifold with a new one. Replacing the intake manifold can be done by competent DIYers. Most shop-rate manuals estimate the labor time for replacing an intake manifold to take around three hours. If you’re too intimidated or have some doubts about handling this repair on your own, we recommend leaving it to the pros.

How Much Does It Cost To Fix The P2015 Error Code?

The cost to repair the P2015 code can vary from vehicle to vehicle and is dependent on the exact issue affecting the vehicle. A simple vacuum hose can be replaced fairly cheaply. If you replace the line yourself, you can expect to pay between $5 and $20. If you have a repair shop handle replacing or cleaning the hose, expect to pay $35 to $50. Replacement aftermarket solenoids can cost as little as $20 and go up to as much as $400 from the OEM. An intake manifold replacement can be rather costly, with OEM manifolds costing as much as $800 and labor costing an additional $700. According to RepairPal, a new intake manifold gasket for a Volkswagen Jetta will cost between $630 and $720. As mentioned, though, the cost of an intake manifold repair can be a lot more for another model.
