How to refill AdBlue in Mercedes-Benz?

What is AdBlue?

AdBlue is a liquid solution made of 67.5% deionized water and 32.5% urea, which is used to reduce harmful nitrogen oxide (NOx) emissions from diesel engines. It is stored in a separate tank in the vehicle and is injected into the exhaust system to neutralize NOx emissions.

How to refill AdBlue in a Mercedes-Benz car?

You can refill AdBlue in your Mercedes-Benz in four simple steps:

  1. Locate the AdBlue filler cap on your Mercedes-Benz car, which is usually located near the fuel filler cap.
  2. Remove the filler cap and pour in the AdBlue solution, being careful not to overfill the tank.
  3. Replace the filler cap and ensure it is securely tightened.
  4. Your car’s onboard computer will automatically detect the AdBlue refill and reset the AdBlue level indicator.

Can I remove AdBlue in a Mercedes?

It is not recommended to remove AdBlue from a Mercedes-Benz car, as it is an essential component of the emissions control system. Without AdBlue, the car will not be able to reduce NOx emissions and may not be compliant with emissions regulations. Additionally, driving without AdBlue can cause damage to the engine and void the vehicle’s warranty.

With an AdBlue Mercedes emulator, however, you can simulate an entire AdBlue system, including the diesel particulate filter (DPF). While installed, it can keep the SCR system inactive when not needed, keeping the Engine Control Unit from causing loss of engine power.

The device is small and extremely simple to install, does not interfere with the car’s electronic system, and allows drivers to save up money on AdBlue and costly maintenance when driving through countries where it’s not required to have a working SCR system at all times. Therefore, it’s a very efficient solution and one that’s worth looking into.
