P2015 code — how to fix error fast
Illuminate your path by knowing the P2015 code. Harness its implications for the ultimate automotive care.
One of the worst things that could happen to a driver is to get a code like P2015 diagnosed in your car. It’s especially annoying when you don’t know anything about the P2015 code meaning, so most drivers will instantly start adding up huge repair figures in their minds. The “check engine” light that may follow the code doesn’t help there, but having more insight into the code surely does.
That’s why our guide will tell you everything you need to know to get to the bright side of driving again with the root cause fixed and the code erased. Follow us on the mission to help you deal with the code in the most cost-effective and simplest way possible.

What does the P2015 code mean?
The P2015 code refers to a problem with the intake manifold runner control circuit. The intake manifold is responsible for regulating the amount of air that enters the engine. The intake manifold runner control (IMRC) system is designed to optimize the flow of air into the engine by adjusting the length of the intake runners. This is achieved through the use of a valve that opens and closes to allow air to flow through different lengths of the intake runners.
When the IMRC circuit malfunctions, the check engine light is triggered, and the P2015 code is stored in the car’s onboard computer. This may result in a reduction in engine performance, decreased fuel efficiency, and potential damage to the engine over time.
What causes the P2015 code?
Even though the code P2015 is triggered by a problem associated with the intake manifold control circuit, there are some other things that may eventually lead to the code or affect the circuit as a consequent action. So, we’ll do our best to give you a list of all the possible reasons behind it, including the following:
Failed intake manifold runner control valve
The valve responsible for controlling the intake manifold runner may fail, either due to age or wear and tear. A faulty valve may cause the IMRC circuit to malfunction, resulting in the P2015 code being triggered.
Symptoms of a failed valve may include rough engine performance, decreased fuel efficiency, and a noticeable reduction in power.
The wiring that connects the IMRC valve to the car’s computer may become damaged or corroded over time, resulting in a malfunction of the IMRC circuit. This may also trigger the P2015 code.
Symptoms of wiring issues may include intermittent check engine lights, sporadic engine performance, and difficulty starting the engine.
Failed IMRC control module
The IMRC control module is responsible for controlling the valve that regulates the intake manifold runners. If the control module fails, it may cause the IMRC circuit to malfunction, resulting in the P2015 code being triggered.
Symptoms of a failed control module may include rough engine performance, decreased fuel efficiency, and a reduction in engine power.
Which car models does the P2015 code affect the most?
his code can affect various car models, but it is most commonly reported in Volkswagen (VW) and Audi vehicles with a TDI engine, such as the following:
- Volkswagen Jetta: The P2015 code is more likely to appear in Jetta vehicles with high mileage or in areas with extreme temperatures.
- Audi A3: This car has known problems with the IMRC module which is known for premature failure and causing the code P2015 to trigger.
- Volkswagen Passat: Volkswagen Passat models with 1.6 TDI and 2.0 TDI engines are known for code P2015 appearing on models with higher mileage.
How to diagnose the P2015 code
There are a number of ways to properly diagnose the code P2015 and it all depends on the underlying issue that caused the code in the first place. Now that you are prepared to do some more diagnostic work, let’s get into the main methods of pinpointing this code:
You can visually inspect the IMRC valve and wiring to check for any signs of damage, corrosion, or wear and tear. If you aren’t that much confident in your skills, you can leave this to a trusted mechanic.
Check electrical connections
By checking the electrical connections between the IMRC valve and the car’s computer you can ensure that there are no loose or corroded connections.
Scan the car’s computer
The mechanic may use a diagnostic scanner to retrieve the P2015 code from the car’s onboard computer. They will also check for any other codes that may be present. While you can use a scanner tool yourself to read the code, a skilled mechanic will likely have more professional diagnostic equipment needed for accurate readings of other associated codes.
Test the IMRC valve
The mechanic will test the IMRC valve to ensure that it is functioning correctly. This may involve using a specialized tool to manually open and close the valve.
How to fix the P2015 code
Once the issue has been properly diagnosed, you can move on with applying fixing methods that work best with particular causes. Here’s our list of the most commonly used solutions for erasing the code P2015:
Replace the IMRC valve
If the valve responsible for controlling the intake manifold runner is faulty, it will need to be replaced. This may involve removing the intake manifold to access the valve.
If the wiring that connects the IMRC valve to the car’s computer is damaged, it will need to be repaired or replaced.
Replace the IMRC control module
If the IMRC control module is faulty, it will need to be replaced. This may involve removing the intake manifold to access the module.
The cost of fixing the P2015 code will depend on the cause of the problem and the make and model of the car. In general, replacing the IMRC valve will cost between $150 and $400, while replacing the control module may cost between $400 and $800.
How to prevent the P2015 code
Regular maintenance can help prevent the P2015 code from appearing. This includes making use of the following steps:
- Timely replacement of the air filters
- Use high-quality fuel
- Keep the engine clean
Regularly replacing air filters can help prevent debris and dirt from entering the engine and causing damage to the intake manifold. On the other hand, using high-quality fuel can help prevent the buildup of deposits in the intake manifold and valves.
Finally, a regular engine cleaning can help prevent the buildup of dirt and debris in the intake manifold and valves.
As it turns out, the code P2015 may not be as harmful as you may have thought initially, but it’s still equally important to deal with the code and remove it on time. You can do this by taking several different steps, but we suggest you rely on the pieces of advice listed in this guide for having the easiest task possible.
What causes the P2015 code?
The P2015 code can be caused by a number of factors, including a faulty sensor, damaged wiring or connections, or issues with the intake manifold itself.
What are the symptoms of the P2015 code?
Symptoms of the P2015 code can include reduced engine performance, increased fuel consumption, and rough idling.
Can I still drive my car with the P2015 code?
It is generally safe to drive your car with the P2015 code, but it is recommended to have it diagnosed and repaired as soon as possible to prevent further damage to your vehicle.
