What is the fault code for AdBlue?
Some common fault codes related to AdBlue include P20EE, P205C, and P20B9. P20EE indicates a malfunction in the AdBlue system, specifically a low exhaust gas sensor; P205C indicates an AdBlue fluid quality issue; and P20B9 indicates a low AdBlue line pressure. Repairing the AdBlue system can be a valid option — especially if your equipment is road-legal, under warranty, or operating in regions with strict emissions enforcement.AdBlue injector issue: The AdBlue injector may be clogged or damaged, causing the system to not be able to properly inject AdBlue into the exhaust system. AdBlue pump issue: The AdBlue pump may be malfunctioning, causing the system to not be able to pump AdBlue into the exhaust system.One of the most frequent issues with AdBlue is crystallization. When exposed to air or not properly managed, AdBlue can crystallize, leading to clogged injectors and filters. This blockage can cause the system to malfunction, leading to increased emissions and potential engine damage.AdBlue systems are designed to reduce emissions, so if you notice increased exhaust smoke, particularly white or grey smoke, it could indicate that the system isn’t working properly. This is often a sign that the injectors are clogged, preventing the AdBlue® from mixing correctly with the exhaust gases.AdBlue Injector Problems: Blockages or malfunctioning injectors affecting the flow of AdBlue into the exhaust system. Sensor Failures: Issues with the AdBlue quality or level sensors that trigger warning lights or system shutdowns.
Is it illegal to disable AdBlue?
DISCLAIMER: Deleting and removing Adblue from a vehicle will deem it illegal for road use and can fail an M. O. T. We Also offer Adblue diagnostics and fixes for your Adblue system. Get a quote above. If you run a diesel vehicle on public roads, an AdBlue delete is not worth the risk — the legal, mechanical, and environmental downsides are too great.
Can I drive with no 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. Over time, your AdBlue® system can become clogged or less efficient, leading to issues that may affect both performance and emissions.If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to limit its emissions. Once you’ve stopped, you won’t be able to restart the engine if the AdBlue tank’s empty. The car will give you plenty of warning that the AdBlue tank is running low.AdBlue added to the fuel tank with the engine running Drain the tank and dispose of the fuel correctly.

With AdBlue, you’ll notice that the car does achieve a higher level of efficiency on the roads and that your car lasts for a lot longer than the typical vehicle.The AdBlue system does not affect the running or performance of the engine itself, it purely exists for emissions control reasons. We can repair, replace or remove your vehicle’s AdBlue system at a fraction of the cost of main dealer prices. Main dealers often have big delays for parts, which mostly don’t affect us.
Can you drive with an AdBlue system fault?
If you run out of AdBlue, your diesel vehicle will not be able to start or continue driving for long. AdBlue is a fluid used in diesel engines to reduce harmful emissions – so, if the AdBlue tank runs dry, the system detects this and triggers a warning on your dashboard. DTCs Present: P20E800 – Reductant Pressure Too Low. The owner reported that he had already topped up the AdBlue (Diesel Exhaust Fluid) but the warning hadn’t disappeared. It is important to note that AdBlue warnings on the dash can be triggered by 2 means: Low AdBlue fluid level. Fault within the AdBlue system.The diagnostic trouble code (DTC) P20E8 indicates “Diesel Intake Air Flow Position Sensor Circuit Low. The powertrain control module (PCM) will trigger this code if the diesel intake air flow position sensor (DIAFPS) sends a signal that doesn’t match normal engine operating conditions.
Can I drive with an AdBlue system fault?
If a SCR-equipped vehicle runs out of AdBlue, it will fail to start. It your vehicle runs out of AdBlue while you are driving then it may enter ‘limp home’ mode, which will reduce engine power to limit its emissions. The injector sprays AdBlue into the exhaust system. If it clogs or fails electronically, the SCR system can’t function properly. You may see a warning like “Check Urea System” or “Engine Start Not Possible in X miles.
