BlueInjection is the cutting-edge SCR diesel technology from Opel that uses AdBlue®* to further reduce the level of nitrogen oxides and work towards cleaner emissions.
*AdBlue® is a registered trademark from Verband der Automobilindustrie e.V.
By owning a vehicle with BlueInjection technology you are helping to reduce harmful nitrogen oxides (NOx) emissions thus reducing your environmental footprint.
Cars fitted with the BlueInjection system need regular AdBlue® top-ups also in between recommended service intervals. But don´t worry, an indicator in the dashboard will inform you when levels are running low.
Top-up yourself thanks to the wide range choice of bottles available. Or just go to your local Opel dealer for the refill.
AdBlue® (also called Diesel Exhaust Fluid) is an odorless, colorless clean and non-toxic fluid that consists purely of 32.5% urea and 67.5% water.
As it is mostly water, it freezes at -11°C (a 32.5% concentration is the lowest freezing point of a urea water solution), so to allow the vehicle to run under all conditions, all AdBlue® tanks are equipped with a heater that will defrost sufficient liquid for the emission reduction.
SCR means Selective Catalytic Reduction and is a technology used for reducing nitrogen oxides (NOx) from the exhaust gas of diesel engines. It is based on AdBlue® (also called Diesel Exhaust Fluid), a 32.5% urea solution in purified water, which is injected into the exhaust pipe. The urea in the AdBlue® releases ammonia (NH3) with the exhaust gas high temperatures and this ammonia reacts with nitrogen oxides (NO and NO2) in the catalytic converter to form harmless nitrogen (N2) and water (H2O) vapor.
SCR technologies are the latest state of technology on the path towards future emission requirements. It is the reason why Opel decided to implement BlueInjection (Opel's SCR technology) to the entire diesel fleet starting as of 2018.
If the AdBlue® tank is empty, the car will not restart once the ignition is turned off! This is not a fault, but a legally required feature of the system. If this stage is reached the system will need a full top-up before the car can be restarted.
We do not recommend to refill at the AdBlue® pumps that exist in many petrol stations for commercial vehicles (trucks and busses) as the flow rate is too high for a passenger car. In addition, most truck nozzles need to be released by a magnet insert in the filler head of the vehicle, which is not present in any Opel passenger car.
The good news is that there is a growing number of petrol stations across Europe, who offer low flow AdBlue® pumps for passenger cars. Refilling with such a pump is as easy as refilling diesel fuel.
If small quantities of AdBlue® come into contact with the vehicle’s paintwork, for example, wipe them off and if necessary rinse the area with water.
If you ever spill some AdBlue® on your clothes and/or hands, just rinse out thoroughly with clear water.
Opel vehicles do not have this option. For each vehicle there is only one tank size that has been designed to optimize package and weight restrictions.
AdBlue® is a registered trademark of the VDA, for which General Motors (Opel's mother company) has a worldwide license covering all brands. It is manufactured by chemical companies, and only licensed manufacturers and distributors may use the name "AdBlue®".
Each AdBlue® tank is equipped with sensors that will trigger a series of messages when the fluid is running low.
There will be three intervals:
Attention! If the AdBlue® tank is depleted, the system will need a full top-up before the car can be restarted.
