If additional lights come on, stop the vehicle and arrange recovery to your dealer. Don't continue to drive as there is a risk of fire! If the light doesn't go off consult your Volkswagen Retailer. The light on your dash board will look like this.ĭrive the vehicle for approx 15 minutes keeping the engine revs between 2000 - 2500 rpm.įor automatic vehicles use the 'S' setting in order to keep the revs up.

At this point you should contact your recovery company or Volkswagen Assistance on 0800 777192 if your VW is under 1 year old (Phaeton & Touareg have a 3 year breakdown cover). If the Emmission Control Light and/or the Engine Managment warning light come on at the same time as the DPF there's a more serious fault. At this point the vehicle must be taken to a VW dealer (See - "What happens if I ignore the light")
When the filter reaches a certain percentage full it can no longer clean itself and neither can you by driving in the correct style. Worse still the Cat/DPF will get so hot in it's attempt to burn off the soot, it can catch fire! If you have a fleet of trucks that have been imported to your country where DEF fluid is not available, your trucks will fail and lose half the power, this is where our DEF delete module comes in and will fix your truck. It won't be covered by warranty and you'll have no change from £600+. The good points for removing the DEF from your truck, one it will save you a lot of downtime when the truck goes into limp mode when the DEF system fails. Firstly the filter will become so blocked it can no longer be cleared, even by your dealer. The simple answer is DON'T! If you continue to drive and simply hope the light will go off (which it won't) you risk two things. Keep the car in a lower than normal gear (use 'S' on an automatic) in order to keep the revs up. You should drive your vehicle for approximately 15 minutes keeping the engine revs between 2000 - 2500 rpm. How to clean, clear and reset (regenerate) the system It's at this point the warning light will come on and your intervention is required. In normal driving this will happen without you being aware but on continued short journeys the particals can build up and remain 'stuck' in the system. The filter collects a certain amount of these harmful deposits and then burns them off at an extremely high temperature (450 degrees c). You may have noticed that modern diesels no longer leave you in a cloud of smelly black smoke when they accelerate off. The Diesel Particulate Filter (DPF) is part of your exhaust and controls the 'soot' that would otherwise be expelled from the system. How it works and why the light may come on
If you attempt to reset a brake service warning without replacing the brake pad warning sensor along with the brakes the vehicle will log a fault code which can only be reset at a BMW dealership. DEF allows the engine to use less exhaust gas recirculation (EGR), and maintain higher oxygen levels for better combustion.Īnd because this process happens automatically in most highway applications, you don't need any special training-saving you both time and money.How to reset/regenerate/clear your DPF warning light (Diesel Particulate Filter) Dont reset services which you havent performed, especially not brake services. The DEF and catalytic converter change the harmful nitrogen oxides into harmless nitrogen and water vapor, and the truck’s NOx emissions register at near-zero levels. Next, before the exhaust reaches the catalytic converter, diesel exhaust fluid (DEF) is mixed in. Here’s how it works: high-NOx/particulate exhaust flows from the engine to Volvo’s diesel particulate filter (DPF), where much of the exhaust’s particulate is removed. Volvo’s Selective Catalytic Reduction (SCR) system is a superior solution to the EPA’s emissions standards, not to mention a fuel- and cost-saving innovation for your fleet. The one-box configuration provides better thermal encasing of exhaust energy, and improves muffler efficiency. Volvo’s “one-box” exhaust aftertreatment system offers smaller system packaging and reduces weight by 17 pounds compared to current systems.
