Common Faults

AdBlue is a diesel exhaust fluid that reduces harmful emissions from diesel engines. AdBlue faults can occur when the AdBlue system is not functioning properly, resulting in engine power loss, warning lights on the dashboard, and reduced fuel economy. Common AdBlue faults include low AdBlue fluid levels, faulty AdBlue injectors, or a malfunctioning AdBlue pump. Regular maintenance and proper use of AdBlue can prevent these faults from occurring and ensure compliance with emissions regulations.

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. Other codes related to AdBlue may also refer to issues with the system's pressure sensors, heater circuit, or injector circuit. These fault codes can be diagnosed and fixed by a qualified technician using diagnostic equipment.

Mercedes AdBlue Faults

One of the common faults that Mercedes vehicles can experience is with AdBlue, a solution used to reduce emissions of nitrogen oxides (NOx) in diesel engines. The AdBlue system can fail, causing warning messages to appear on the dash and potentially resulting in reduced performance or even the car going into "limp mode." In some cases, the issue may be related to the distance traveled since the AdBlue tank was last filled, with some models requiring regular top-ups every few thousand miles. Regular maintenance and ensuring the AdBlue tank is kept topped up can help prevent these issues.

Adblue faults in Mercedes vehicles refer to issues with the diesel exhaust fluid system that reduces harmful emissions. These faults can cause warning lights to appear on the dashboard, reduced engine power, and even prevent the engine from starting. Common causes of adblue faults in Mercedes vehicles include faulty sensors, contaminated or low-quality adblue fluid, and issues with the adblue tank or injector system. Regular maintenance, including adblue fluid top-ups and system checks, can help prevent adblue faults and keep your Mercedes running smoothly.
