Does a VW Golf need AdBlue?
The Volkswagen low emission system uses a DeNOx catalyst, diesel particulate filter and injection of AdBlue. It is recommended that AdBlue is added to your diesel engine every 10,000 miles or every 6 months, whichever comes first. In general, it is advised to check the AdBlue tank level every time you fill up with diesel. If the tank is low, refill it in order to ensure that your engine is running cleanly and efficiently.Like putting diesel into a petrol car and vice-versa, adding AdBlue to the diesel tank, or diesel to the AdBlue tank, can have catastrophic consequences for the engine and fuel/AdBlue system. Either scenario will set off a chemical reaction and pollute the tank.AdBlue is commonly mistaken as a fuel additive when it is actually an exhaust fluid that should never be mixed with diesel. AdBlue has its own tank and is stored completely separately to your vehicle’s fuel. Adding AdBlue into your diesel fuel tank can cause thousands of pounds worth of damage.Impact of AdBlue on Engine Performance The use of AdBlue helps ensure that the engine continues to run efficiently by reducing exhaust emissions. By ensuring that the exhaust system operates at its best, the engine can potentially perform better, which can indirectly affect fuel efficiency.Diesel Exhaust Fluid (DEF) also known as AdBlue®, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, it is injected into the exhaust system to clean exhaust gases.
How much AdBlue to put in a VW Golf?
A passenger car can consume approximately 1. AdBlue® every 620 miles (1. Passat and Passat Estate). The truth is that this depends on the car’s engine, how many miles you do and how you drive. A general rule of thumb though is that 1 litre of AdBlue is used up every 600 miles.Cars and SUVs: Typically, passenger cars consume AdBlue at a rate of about 1 liter for every 600-800 kilometers. The exact rate will depend on the engine type and driving conditions. Trucks and Commercial Vehicles: These vehicles tend to have larger engines and may require more frequent AdBlue top-ups.The average distance that a full tank of AdBlue will last is 6,000 to 7,000 miles. Typically, 1 litre lasts for around 600 miles but your driving style may impact this. Since travelling between 6,000 and 7,000 miles will empty your tank, we recommend topping up every 5,000 miles just in case.On a VW T6. AdBlue tank can hold 13 litres. This will typically last you 6000 miles. Like your fuel, the AdBlue level can be displayed on your dashboard anytime you need to check it.
What is the AdBlue warning on VW Golf?
The white warning will appear when the remaining range of AdBlue® is approximately 1,500 miles, and is repeated every 62 miles until the range reaches 1,000 miles, at which point the warning turns amber. This warning is repeated every 31 miles and is accompanied by an audible tone. On average, 1 litre of AdBlue® should last around 1,000km, however usage can be higher depending on how the vehicle is driven and the conditions that the vehicle is subjected to. If the amount of AdBlue® in the vehicle reaches the minimal level before an A or B Service, a message will appear on the instrument cluster.
How do I know if my VW needs AdBlue?
The amber warning will appear when the remaining range of AdBlue® is approximately 1,000 miles. This warning is repeated every 31 miles and is accompanied by an audible tone. If these warnings are not acted upon, the warning turns red; once this happens the car will not restart once the ignition is turned off. Consequences of Running Out of AdBlue: Running out of AdBlue may trigger a reduction in engine power and efficiency, affecting the overall performance of the vehicle. Warning Indicators and Reduced Speed: Most vehicles with AdBlue systems are designed to display warning indicators when the fluid level is low.Technically, a diesel engine can still operate if it runs out of AdBlue; however, in practice, most modern diesels are designed to prevent this. When AdBlue is low or absent, engine performance is often restricted to “limp mode,” limiting speed and power to encourage refilling.Checking your AdBlue® level Finding out whether you have an adequate amount of AdBlue® in your tank is usually straightforward enough – an amber dashboard warning light will typically alert you when your tank needs a refill.If you run out of AdBlue™, your vehicle will not re-start after you turn off the engine – this is a condition of the EU6 emissions legislation and applies to all types of vehicles. The AdBlue™ tank will need to be refilled with a minimum of approximately 3-5 litres of AdBlue™ before the vehicle will start.
Do Volkswagen diesels use AdBlue?
The system uses a Diesel Oxidation Catalyst (DOC), combined with a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) which utilises the periodic injection of the AdBlue® solution. Does running out of AdBlue™ damage the vehicle’s engine? No, the engine will not be damaged if you run out of AdBlue™. You can proceed to the next AdBlue™ distribution point or use your emergency supply at the next safe stop if you have this on board. However, engine performance could be affected until you fill up.When used correctly, AdBlue does not damage diesel engines. It plays a crucial role in reducing NOx emissions and ensuring compliance with emission standards. However, mishandling, contamination, or adding AdBlue to the fuel tank can cause significant problems, including damage to the fuel system and SCR components.AdBlue™ is not compatible with many materials so it can corrode the pipework and components in the fuel system. This can cost thousands of pound worth of damage, not to mention the loss of use of the vehicle until a professional gas drained the tank, flushed out the system and carried out all repairs.Improved Efficiency – By reducing NOx emissions, AdBlue helps improve engine efficiency and performance. Longevity of DPF System – AdBlue works alongside your DPF to ensure the exhaust gases are cleaner, reducing the harmful particles that cause DPF blockages.
Can I run my diesel without AdBlue?
Adblue is not physically required to run an engine, but running an engine without it will cause the vehicle emissions to exceed what’s legally permitted, so the vehicles are programmed to refuse to start if it runs out. Some will restrict performance if the adblue runs low, again to reduce emissions. If you ignore the warnings and run out of AdBlue, your power and performance will be limited until you top up again. If you’re completely out of AdBlue, your car won’t start. So if you are running low, make sure to top up your tank to avoid the inconvenience of a breakdown.You should never allow your car to run out of AdBlue. If it does, the engine will go into ‘limp’ mode, drastically reducing power to keep NOx emissions within legal limits. A warning will appear on the driver’s display, and you should refill the AdBlue tank as soon as possible.What Happens if I Run out Of AdBlue? If you run out of AdBlue while driving, the engine’s performance will be reduced to limit emissions. Once stopped, you cannot restart the engine if the AdBlue tank is empty. The car or van will give you plenty of warning that the AdBlue tank’s running low.Technically, it’s safe to drive to a refueling station if you still have AdBlue left, but if you completely run out, the vehicle will eventually prevent you from driving to avoid damaging the engine. It’s essential to top up the AdBlue as soon as possible to avoid these issues.
