What is BlueTEC diesel engine technology?

BlueTEC engine technology by Mercedes-Benz reduces emissions from our cutting-edge diesel engines while at the same time lowering fuel consumption.

BlueTEC brings together an array of advanced technologies for the effective reduction of fuel consumption and emissions in Mercedes-Benz diesel vehicles, including the after-treatment of exhaust gases by a SCR catalytic converter (SCR = Selective Catalytic Reduction) with the injection of an additive called AdBlue. This technology converts harmful nitrogen oxides in the exhaust gases into natural constituents of the air we breathe: nitrogen and water.

BlueTEC technology has proven itself in a wide range of Mercedes-Benz passenger cars and commercial vehicles, having first been introduced in
Mercedes-Benz trucks at the beginning of 2005, and then in passenger cars in 2008.

Reduced emissions.

Thanks to BlueTEC technology, the Vito, V-Class and Valente already meet the future stringent Euro 6 emissions standard. Euro 6 requires a reduction of harmful nitrogen oxides by 55% compared to the current Euro 5 standard, making the Vito, V-Class and Valente some of the most sustainable diesel vehicles on the road today.

Reduced fuel consumption.

As well as being more sustainable, the new BlueTEC engines are also more fuel efficient. With fuel consumption from 6.0 L/100km the new Vito is up to 26% more fuel efficient with BlueTEC technology

Improved performance.

Performance is not compromised in delivering less emissions and reduced fuel consumption. In fact, the new BlueTEC engines deliver up to 6.5% more torque, contributing to your long-term success every kilometre of the way.

To function properly, BlueTEC diesel engines require AdBlue to comply with the stringent Euro 6 emissions standard and maintain the vehicle’s performance. The following is general information on AdBlue, however for further information please refer to the vehicle’s Operating Instructions, or contact an authorised Mercedes-Benz Dealer.

What is AdBlue?

AdBlue is an aqueous solution of urea and de-ionised water. AdBlue is not a fuel additive and must not be added to the fuel tank.

Where does AdBlue need to go in the vehicle?

AdBlue must only be filled into the vehicle’s separate AdBlue tank. The AdBlue filler neck is located behind the fuel filler flap near the passenger door.

How often does AdBlue need to be used?

Similar to fuel consumption, AdBlue use can vary depending on your driving style and the vehicle’s operating conditions. On average, 1–1.5 litres of AdBlue should last approximately 1,000 kilometres, however this may vary.

If the supply of AdBlue is almost empty, the display shows the Refill AdBlue message in good time. If you continue driving without refilling the AdBlue tank, you will only be able to drive the vehicle the maximum distance shown.

If you operate the vehicle without AdBlue, the emissions standard will no longer be met, and the engine management system subsequently prevents the engine being started again until AdBlue is added to the AdBlue tank. Therefore top up the AdBlue tank regularly during vehicle operation or, at the latest, after receiving the first warning message via the on-board computer.

Where can I get AdBlue?

AdBlue is available from authorised Mercedes-Benz dealers and many service stations, for example Shell (

During the manufacturer’s warranty period of your Vito, Valente or V-Class, or whilst under a Mercedes-Benz Service Plan, AdBlue Refill is complimentary from any authorised Mercedes-Benz Vans Dealer.

Remember to top up the AdBlue tank regularly or, at the latest, after receiving the first warning message via the on‑board computer.
