What is the use of AdBlue on our cars?
AdBlue is used in many current diesel automobiles to meet emission requirements. This is true not only for trucks, huge commercial vehicles, ships, and tractors, but also for various sorts of passenger vehicles.
AdBlue, also known as Diesel Exhaust Fluid or AUS 32, is a clear mixture of demineralized water and pure urea (32.5 percent). It is intended to convert dangerous nitrogen oxide (NOx) emissions from diesel automobiles to non-hazardous gases in order to meet more strict emission requirements.
FAQS About AdBlue
AdBlue: How Does It Work?
AdBlue is injected in trace volumes into the exhaust gas stream. AdBlue decomposes into ammonia and carbon dioxide at high temperatures, acting as a catalyst to convert toxic nitrogen oxides to innocuous nitrogen and water.
How do I top up my car’s AdBlue?
Most AdBlue tank filler spouts are situated next to the diesel filler, and they usually have a blue cap. Other common places for fillers include the boot and spare wheel well. The owner’s handbook should tell you its location.
What Happens If You Run Out Of Adblue In Your Car?
If you run out of AdBlue while driving, the engine’s power and performance will be lowered to ‘limp home’ mode to prevent emissions, and the engine will not restart until the AdBlue tank is replaced.
The dashboard will notify you when the AdBlue tank is going low – normally with around 1500 miles of supply remaining, followed by an amber warning light when the tank is nearly empty.
What Should I Do If I Accidentally Fill The AdBlue Tank With Diesel?
Avoid starting the engine and instead contact your dealer or breakdown service provider to arrange for the tank to be emptied. If you start the engine, you risk causing damage to the selective catalytic reduction and AdBlue injection systems, which may need the replacement of these components.
What Should I Do If I Mix AdBlue With Diesel?
In the event that I put AdBlue in the diesel tank, what should I do? Do not start the engine, since doing so could result in the engine and fuel system being completely destroyed. In order to have the car’s fuel tank emptied and flushed out, contact a breakdown business or misfuelling service provider.
The procedure for resetting the AdBlue warning light
There is no way to manually reset your AdBlue warning light – the only thing you can do is top it up with more AdBlue. Following a successful replenishment to the bare minimum, the warning light will be turned off.
Alternatively, if the AdBlue has not been reset, OBD Diagnostic tools that support the AdBlue Reset, such as the Launch X431 OBD Diagnostic Scanner, can be used to do a reset.

- Wait for the glow plug light to stop blinking. Then turn off the ignition.
- Wait 10 seconds with the ignition off.
