B-Class Euro 6: Specifications at a Glance

To give you a clearer picture, here’s a look at typical specifications you might find in a B-Class Euro 6. Please note that exact figures can vary by model year, engine variant, and specific options.

Note: WLTP (Worldwide Harmonised Light Vehicle Test Procedure) is a standardized method for measuring fuel consumption and CO2 emissions. AdBlue is essential for the SCR system on diesel engines to meet Euro 6 regulations.

Understanding AdBlue for Diesel B-Class Models

If you’ve opted for a Euro 6 diesel B-Class, you’ll encounter AdBlue. This is a crucial component for meeting the strict NOx emission standards.

What is AdBlue?

AdBlue is a liquid solution composed of de-ionized water and urea (approximately 32.5%). It is not a fuel additive; it is injected into the exhaust system of diesel vehicles.

How AdBlue Works (SCR System)

1. Injection: A small amount of AdBlue is sprayed into the exhaust stream before the Selective Catalytic Reduction (SCR) converter.
2. Heating: The heat from the exhaust gases converts the urea in AdBlue into ammonia.
3. Conversion: Inside the SCR converter, the ammonia reacts with harmful nitrogen oxides (NOx) from the exhaust.
4. Output: This reaction converts NOx into harmless nitrogen gas and water vapour, which are then emitted from the tailpipe.

Managing Your AdBlue Levels

Refilling: Your B-Class will have a separate AdBlue filler cap, usually located next to the diesel fuel filler cap or in the boot.
Range Indicator: The car’s onboard computer will alert you when your AdBlue level is low, typically when it’s around 2400 km (1500 miles) from empty. It will provide increasingly urgent warnings as the level drops further.
Crucial Warning: It is vital to refill the AdBlue before the tank runs empty. The car will not restart if the AdBlue tank is empty and the engine has been switched off, as it’s a legal requirement to meet emissions standards.
Where to Buy: AdBlue is readily available at most fuel stations, car accessory shops, and online.

Using the correct Diesel Exhaust Fluid (DEF), often branded as AdBlue, is essential for the system to function correctly. You can find more detailed information on the European Automobile Manufacturers’ Association (ACEA) page.
