Mercedes-Benz Genuine AdBlue® is composed of urea and de-ionised water. It is injected into the exhaust gasses of selected diesel engines as a post combustion process. Mercedes-Benz vehicles using AdBlue® technology are identified with the ‘BlueTEC’ symbol. AdBlue’s® purpose is to reduce the percentage of harmful NOx (Nitrogen Oxide) found in the vehicle’s emissions. With BlueTEC technology, Mercedes-Benz has been able to heavily reduce exhaust gas emissions while at the same time maintaining the performance of diesel engines in terms of power and torque output.
Mercedes-Benz Genuine AdBlue must only be poured into the vehicle’s separate AdBlue® tank – AdBlue® must not be put into the diesel fuel tank. Do not mix AdBlue® with any additives and do not dilute AdBlue® with water.
The vehicle will not operate unless there is sufficient AdBlue® in the vehicle’s AdBlue® tank. The size of the AdBlue® tank has been designed so that a customer should not have to refill AdBlue® in between service intervals, however an individual vehicle’s AdBlue® consumption may be higher depending on operating conditions.
On average, 1 litre of AdBlue® should last around 1,000km, however usage can be higher depending on how the vehicle is driven and the conditions that the vehicle is subjected to.
• Every A Service AdBlue® tank is refilled / topped up
• Every B Service AdBlue® tank is drained and refilled
If the amount of AdBlue® in the vehicle reaches the minimal level before an A or B Service, a message will appear on the instrument cluster.
No. You should use all of the Mercedes-Benz Genuine AdBlue product in the bottle at the one time and then put the empty bottle in the recycling bin. Once opened and exposed to air, AdBlue® bottles with leftover AdBlue® fluid cannot be stored as the purity of the fluid will be compromised.
Yes. Due to the limited durability of AdBlue®, AdBlue® has a 2 year lifespan from date of production. It is essential that AdBlue® is stored between minus 5 degrees and 20 degrees Celsius. AdBlue® can decompose if it is stored at 30 degrees or more for extended periods of time - ammonia can form in such instances.
