What You'll Learn
Seek professional help or do it yourself?
Resetting the anti-pollution system yourself can be a viable option if you are a car enthusiast or simply keen to learn. However, it is important to take the necessary precautions and consult the owner's manual. Acting swiftly is crucial to keep your car running smoothly and to avoid legal consequences.
Before attempting any DIY solutions, ensure you are in a safe environment. Park your car on a flat surface, turn off the engine, and disconnect the battery to avoid the risks of short circuits and personal injury. Basic tools like screwdrivers, spanners, and gloves are recommended. An OBD-II scanner can help you identify fault codes related to the anti-pollution system, which you can then clear to reset the warning light.
If the issue is minor, such as a clogged catalytic converter, simply taking your vehicle for a longer drive may resolve the problem. Adding an adblue cleaner during refueling can also help keep the system clean. However, if the issue is more serious, such as a faulty temperature sensor or problems with the AdBlue ECU, professional assistance may be required.
While DIY solutions can save you time and money, if the warning light reappears, it indicates a deeper issue. Consulting a professional mechanic or Renault customer service may be necessary to avoid causing further damage to your vehicle. Regular check-ups and maintenance can help prevent issues and save you money in the long run. Additionally, keeping your vehicle's software up to date is important, as cars have become more like computers on wheels.
If you are unsure about tackling the issue yourself or if DIY solutions are ineffective, it is advisable to seek professional help. This may involve taking your vehicle to a repair shop or contacting Renault customer care for assistance.

Clearing fault codes
Resetting the Anti-Pollution System yourself can be a good option if you are a car enthusiast or simply eager to learn more about your vehicle. However, it is important to take the necessary precautions to avoid any potential issues. Here is a detailed guide to help you tackle the issue effectively and safely:
First, ensure that you are in a safe environment. Park your car on a flat surface, turn off the engine, and disconnect the battery. Working on an electrical system with the battery connected can lead to short circuits and pose safety risks. It is also recommended to have basic tools like screwdrivers, spanners, and gloves for protection.
An OBD-II scanner is a crucial tool in this process. It can read fault codes from your car's computer, helping to identify the specific issue. Connect the OBD-II scanner to the port, usually located under the dashboard. Turn on your car's ignition but do not start the engine. The scanner should display fault codes, including those related to the Anti-Pollution System, such as P0401, P0402, and P0420.
After identifying the relevant fault codes, you have the option to clear them. This will reset the warning light on your dashboard. However, if the underlying issue is not addressed, the warning light may reappear. If the issue persists, try disconnecting the battery for about 15 minutes to allow the car's computer to reset. Reconnect the battery and start the car to check if the warning has disappeared.
Once the battery is reconnected and the car is running, use the OBD-II scanner again to verify if the fault codes have cleared. If the issue remains unresolved, it may be necessary to seek professional assistance. While DIY solutions can be cost-effective and time-saving, a persistent warning light indicates a more serious problem. Consulting a mechanic or contacting Renault customer service, especially in the case of software glitches, can help prevent further damage to your vehicle.
Remember, regular maintenance and software updates are essential to preventing future issues with your Anti-Pollution System. Keeping your vehicle well-maintained can help identify problems early on and save you money in the long run.

Disconnecting the battery
Locate the battery in your car's engine bay. You may need to refer to your car's manual or seek guidance specific to your car model if you are unsure. Once located, carefully disconnect the battery. It is recommended to leave the battery disconnected for about 15 minutes. This allows the car's computer to reset, which can potentially clear the fault, especially if it is not a severe hardware issue.
After disconnecting the battery, reconnect it and start the car to see if the anti-pollution fault warning has disappeared. This process of disconnecting and reconnecting the battery can help reset the car's computer and clear any temporary glitches that may have triggered the fault.
While disconnecting and reconnecting the battery can be an easy fix, it is important to note that it may not address the root cause of the issue. The anti-pollution fault could be due to various reasons, such as a faulty EGR valve, spark plugs, or sensors. Therefore, it is advisable to use a diagnostic tool, such as an OBD-II scanner, to retrieve specific error codes and accurately identify the problem. This way, you can address the underlying issue and prevent the fault from reoccurring.
If you are unsure about the cause of the anti-pollution fault or how to proceed, it is always best to consult a professional mechanic or seek advice from a trusted car forum or community. They can provide tailored solutions and ensure that your car's anti-pollution system is functioning optimally.

Common fault codes
The "anti-pollution" fault is a generic error that is associated with many issues. To reset the fault, you must first diagnose the specific problem. This can be done by connecting the car to a code reader or diagnostic tool, such as an OBD-II scanner. These tools can retrieve error codes, which will help pinpoint the issue.
Some common fault codes and their potential causes include:
- P1035 and P0031: These codes are related to the air pollution warning message and may indicate a faulty engine ECU.
- Fault codes for the thermostat heater control: These could be caused by the failure of the coolant temperature sensor/gauge, resulting in an overheat warning light on the dashboard and constant running of the coolant fan.
- Fault codes for the oxygen 02 sensor: This could be due to a non-functioning lambda sensor circuit, which can lead to MOT emissions failure.
- P0336 and P0337: These codes are related to the engine speed sensor (crank sensor) and should be addressed first.
- Fault codes for various engine sensors: This could indicate ECU failure, resulting in engine misfires.
Once the issue has been identified and addressed, use the diagnostic tool to clear the fault codes and reset the warning light. It is important to address anti-pollution faults with responsibility and professionalism, as they can have serious environmental and health impacts.

Causes of anti-pollution faults
The "Anti-Pollution Fault" message is a warning that indicates a potential issue with a vehicle's emission control system. This fault is common in Peugeot 207s, particularly those fitted with 1.4 or 1.6 VTI petrol engines. The fault can be triggered by various issues, many of which are connected directly or indirectly to the engine ECU (Engine Control Unit).
One cause of the fault is a malfunctioning oxygen or O2 sensor. This can be due to a failure to receive signals from the sensor because of issues within the ECU's internal circuits. A faulty oxygen sensor can lead to increased emissions and potential damage to the engine. Another cause could be a faulty catalytic converter. A clogged catalytic converter can restrict airflow and disrupt the fuel-air mixture, increasing pollution levels and triggering the anti-pollution fault.
Other causes include clogged diesel particulate filters, incorrect air/fuel mixtures, and issues with the exhaust gas recirculation (EGR) system. In some cases, the fault may be due to a missing signal to the ignition coils, resulting in misfires or a non-starting engine. A comprehensive remanufacture may be required to resolve this issue.
It is important to address the underlying cause of the anti-pollution fault to ensure the vehicle meets emission standards and operates efficiently. A qualified technician should inspect the vehicle promptly to diagnose and resolve the issue.
