The AdBlue system is a crucial part of your 2013 Volkswagen Passat’s emissions control system. It helps to reduce harmful nitrogen oxide (NOx) emissions, which are detrimental to the environment. However, you may encounter a situation where the AdBlue light illuminates on your dashboard, indicating a problem with the system.
This light can be triggered by a number of reasons, such as low AdBlue fluid level, a faulty sensor, or a software glitch. The good news is that many times, a simple reset of the system can resolve the issue.
How to Reset the AdBlue Light
Here’s a step-by-step guide on how to reset the AdBlue light on your 2013 Volkswagen Passat:
- Park your vehicle on a flat surface and engage the parking brake.
- Turn the ignition key to the “ON” position but don’t start the engine.
- Press the accelerator pedal to the floor and hold it for 10 seconds.
- Release the accelerator pedal and turn the ignition key to the “OFF” position.
- Wait for 5 seconds and then turn the ignition key to the “ON” position again.
- Start the engine and check if the AdBlue light has been reset.
If the light persists, you might need to take your vehicle to a qualified mechanic or a Volkswagen dealership for further diagnosis. It’s important to address this issue promptly, as driving with a malfunctioning AdBlue system can lead to performance problems and potentially damage your engine.
Why You Might Need to Reset the AdBlue Light
There are several reasons why your AdBlue light might come on, some of which can be easily resolved with a reset. Here are some common causes:
- Low AdBlue Fluid Level: The most common reason is simply running low on AdBlue fluid. The system will notify you when the fluid is getting low.
- Faulty AdBlue Sensor: If the AdBlue sensor malfunctions, it can provide incorrect readings to the system, leading to the light illuminating.
- Software Glitch: Sometimes, a software glitch within the AdBlue system can cause the light to come on.
