The exhaust system of a car is made up of several key components that help fight pollution. Performing a Car Diagnostics Scanner check can be necessary to inspect them.

Clogged EGR Valve: How to clean it?
Since the implementation of European anti-pollution standards, manufacturers have introduced the “ EGR valve”. This system helps reduce the emission of health-harming toxic gases.
However, despite technological advancements, this exhaust system component remains problematic, mainly due to soot build-up from combustion that clogs the valve and may lead to pollution issues.
DPF: How to regenerate the Diesel Particulate Filter (DPF)?
The Diesel Particulate Filter (DPF) is another commonly problematic part. Like the EGR valve, it needs cleaning to remove built-up soot, which involves triggering the DPF regeneration system in your vehicle.
This system, originally designed for diesel vehicles, is meant to self-clean automatically without mechanic intervention. Unfortunately, many diesel cars used mainly for short urban trips do not allow proper DPF regeneration.
Faulty Oxygen Sensor: How to test a lambda sensor?
The oxygen sensor, also known as the lambda sensor, has been used since the 1990s in petrol vehicles.
Following the EURO1 standard, the lambda sensor was introduced to reduce pollutant emissions and lower fuel consumption.
However, when faulty, the oxygen sensor can cause issues by failing to regulate emissions properly, which can lead to a failed vehicle inspection.
Clogged catalytic converter: How to fix the catalytic converter?
Understanding how the catalytic converter works can be complex. Since the EURO1 standard was introduced, the catalytic converter has become essential for filtering out harmful gases to protect health and the environment.
The catalytic converter was developed to reduce pollutant emissions. Its complex operation makes it a vital element in combating vehicle emissions through a catalytic reaction process.
AdBlue fluid in vehicles: What is it used for?
AdBlue fluid was initially mandatory for trucks and later introduced in diesel cars. Its purpose is to reduce pollutants emitted from the exhaust system.
Since 2015, with the enforcement of Euro 6 standards, AdBlue has been installed in cars. But questions remain about the effectiveness and functioning of this anti-pollution system.
