ADBLUE® – MAKING YOUR DIESEL BMW THE CLEANEST YET.
BMW continually strives to reduce emissions by making exhaust gases cleaner. That also applies to diesel emissions, and today’s Blue Performance Diesel engines are BMW’s cleanest yet – thanks to AdBlue® technology*.
Meeting stringent standards
To help meet European legislation (EU6), the latest BMW Blue Performance diesel engines are fitted with Selective Catalytic Reduction (SCR technology). This uses Diesel Exhaust Fluid (DEF), also known as AdBlue®.
The system injects a small amount of AdBlue® into the exhaust system as you drive. BMW’s advanced diesel engines already achieve lower CO2 emissions than comparable petrol engines, and with SCR technology the levels of NOx emissions are closely comparable too. So you can choose BMW Blue Performance diesel with a clear conscience.
How AdBlue® works
AdBlue® is a non-toxic solution that is stored in a separate reservoir on the car. As you drive, small amounts are injected into the exhaust, breaking down nitrogen oxide (NOx) emissions into harmless water vapour and nitrogen gas and reducing the levels of NOx emissions by up to 90%.AdBlue® technology is proven, fuss-free and does not affect the driving experience.
Which BMW models use AdBlue®?
BMW has been using SCR technology since the 2016 Model Year on its larger-engined diesel models, and from Spring 2018 all new BMW diesel models were equipped with SCR and use AdBlue®. Your BMW service technicians will be able to tell you if your BMW diesel uses AdBlue®. Alternatively, simply consult your owner’s handbook.
Refilling the AdBlue® reservoir
Typically, a litre of AdBlue® lasts around 800-1,000 miles, depending on how you drive. For most drivers a refill will only be needed around once a year or when your BMW is serviced. Your BMW’s driver information panel will give you advance warning when your AdBlue® level is low in plenty of time to book a refill.
If you need an AdBlue® refill before your next services is due, simply drop in on your nearest BMW Centre and they’ll refill your tank for just £1 per litre. Alternatively, most filling stations sell AdBlue® in top-up bottles.
Where do I find the AdBlue® reservoir filler?
AdBlue® is stored in a separate tank; please refer to your Owner’s Handbook to identify the filler location or drop in at your BMW Centre and ask them to show it to you.
What happens if I run out of AdBlue®?
It’s extremely unlikely that you will ever totally run out of AdBlue®: if the reservoir is running low you will receive clear warnings on the driver display, giving you ample time to purchase a top-up either from your BMW Centre or a local filling station.
If the ADBlue® reservoir does run dry, the car will not start. This protects the SCR technology and prevents the car coming to any harm. Refilling the reservoir will allow you to continue driving.
