AdBlue is an essential fluid for many modern Peugeot diesel cars. This guide explains what AdBlue is, how it works, and how to refill it in your Peugeot.
What is AdBlue and Why Do Peugeot Cars Need It?
AdBlue, also known as Diesel Exhaust Fluid (DEF), is a non-toxic, colorless liquid composed of urea and deionized water. It’s injected into the exhaust system of diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology. Peugeot uses AdBlue to meet stringent Euro 6 emissions standards by significantly reducing harmful nitrogen oxide (NOx) emissions.
How the AdBlue System Works in Your Peugeot
Your Peugeot’s SCR system works in conjunction with the Diesel Particulate Filter (DPF). After the DPF captures soot particles, the exhaust gases pass into the SCR catalyst. Here, AdBlue is injected and, due to the high exhaust temperatures, transforms into ammonia. The ammonia then reacts with NOx, converting it into harmless nitrogen and water vapor. This process dramatically reduces your Peugeot’s environmental impact.
Refilling AdBlue in Your Peugeot: A Step-by-Step Guide
The AdBlue tank in your Peugeot is separate from the fuel tank and usually has its own filler cap, often located next to the fuel filler or in the boot. You’ll need to refill AdBlue periodically, typically every 6,000 miles, though this can vary depending on your driving style and journey types. You can purchase AdBlue at most petrol stations and auto parts stores.
Important Considerations:
- AdBlue is not a fuel additive: Never add AdBlue to your Peugeot’s fuel tank. Doing so can cause serious damage to the engine.
- AdBlue is separate from DPF additive: Don’t confuse AdBlue with DPF additive. They are distinct fluids with different purposes and separate reservoirs.
Keeping Your Peugeot Running Smoothly with AdBlue
By understanding how AdBlue works and ensuring it’s refilled regularly, you can contribute to a cleaner environment and keep your Peugeot running efficiently. If you have any questions about AdBlue or your Peugeot’s SCR system, consult your owner’s manual or a qualified Peugeot technician.
