A car’s evaporative emission control (EVAP) system consists of several components like the purge valve. It prevents the fuel vapours from escaping into the atmosphere. When pressure accumulates, the purge valve directs these vapours to combust in the engine, reducing the car’s emissions. That said, a functional purge valve is necessary for a vehicle’s good fuel efficiency and overall performance.    

Here, we have penned the importance and working of a purge valve, the factors that affect its performance and how to fix these issues. 

Where Is the Purge Valve Located?

In most car models, the purge valve is connected to the charcoal canister, which stores fuel vapours from the fuel tank. The valve is mounted on or near the intake manifold or car throttle body, as it needs to be close to the engine for efficient vapour delivery during combustion. However, in some cars, the purge valve location is found in the canister. Professional car inspection services by dubizzle can also help locate the purge valve.

How Does A Purge Valve Work?

A purge valve in a car manages and reduces the release of fuel vapours into the atmosphere. The system captures and stores fuel vapours from the fuel tank in a charcoal canister when the engine is off, preventing them from escaping into the air. When the engine runs, the purge valve opens and draws the vapours into the engine’s intake manifold and burns them during combustion.

Moreover, in modern cars, the engine control module (ECM) or car computers control the purge valve. It determines the optimal time to activate the valve. Besides, factors such as engine temperature, throttle position and the status of the evaporative emissions control system are taken into account.

By analysing these inputs, the ECM optimises the purge valve function for efficient combustion of fuel vapours. This control mechanism helps the vehicle comply with environmental regulations and maintain optimal fuel efficiency.

Reasons a Car’s Purge Valve Malfunctions 

A car’s purge valve may malfunction due to various reasons and these issues can impact its ability to effectively control fuel vapour emissions. Some common reasons for purge valve malfunctions include:

Mechanical Failure

Over time, the purge valve experiences mechanical wear and tear, leading to issues such as sticking, binding or failure to open or close properly. This disrupts the normal operation of the valve and affects its ability to control the flow of fuel vapours.

Electrical Problems

The purge valve is often electronically controlled by ECM. Electrical issues, such as damaged wiring, faulty connectors or problems with the ECM itself interfere with the purge valve function.

Vacuum Leaks

The purge valve relies on a vacuum to operate. If there are leaks in the vacuum lines or connections associated with the purge valve, it can lead to a loss of vacuum pressure, affecting the valve’s performance. 


symptoms of a bad purge valve and why it happens
The buildup of dirt and debris clog the valve and hinders its movement and operation

Dirt, debris or carbon buildup in the purge valve hinders its movement and compromises its ability to open and close. Contamination can occur over time, particularly if the engine is exposed to harsh driving conditions or poor-quality fuel.

Auto Anatomy: EGR Valves

  • EGR Valve Working
  • Causes of a Failed EGR System
  • Symptoms
  • Fixes
  • FAQs

Since air contains nitrogen, oxygen and inert gases, a human breathes nearly 78% nitrogen from the air alongside oxygen. Besides, a car needs air to burn the fuel. That said, if the engine combusts the air-fuel mixture at high temperatures, it can produce nitrogen oxides (NOx), which is harmful to the environment. However, conventional vehicles come equipped with exhaust gas recirculation (EGR) valves.

The valve improves fuel efficiency and reduces the NOx ofconventional cars. But how does it work? Let’s find all the details on the EGR valve, its working and the symptoms of a clogged valve.

How Does an EGR Valve Work?

Functioning of the EGR valves
An EGR system circulates the exhaust gases in the engine’s combustion chamber to reduce the temperature

The EGR valve is a component in the engine’s intake manifold. Controlled by an engine control unit (ECU) or car computers, the function of an EGR valve in the car is to regulate the flow of exhaust gases into the intake manifold.

It receives signals from the ECU to recirculate the optimal amount of exhaust gases. That said, it increases the engine efficiency. At a steady acceleration, the valve opens and allows the exhaust gases to flow into the intake manifold. Then, these gases mix with the fresh air-fuel mixture. 

Since exhaust gases contain low oxygen content, they are difficult to burn. It reduces the engine combustion temperature. With lower combustion temperatures, the EGR valve helps inhibit the nitrogen oxide (NOx) formation. 

Different types of car sensors, such as engine load, temperature and speed sensors, send signals to the ECU. This helps function the EGR valve accordingly. Moreover, the load will be high when climbing the hill. In that case, ECU sends signals to close the EGR valves. This allows the engine to operate at higher temperatures and produce optimal performance.

Reasons Behind EGR Valve Failure

Reducing nitrogen oxide and improving vehicle performance and fuel economy, the EGR system can be subject to malfunction. Before we delve into its symptoms, let’s learn about the causes of EGR valve failure.

Carbon Buildup and Clogging

Over time, carbon can accumulate on the valve and its passages, restricting proper operation. This carbon buildup can occur due to incomplete combustion and the recirculation of exhaust gases. Besides, the valve can get clogged with debris, dirt or soot. Obstructing the flow of exhaust gases, clogged EGR valves affect the performance. Clogging is a result of poor fuel quality, engine oil contamination or general wear and tear.

Faulty Valve Position Sensor

The valve includes a position sensor to monitor its opening and closing. However, if this sensor fails, it gives incorrect valve positioning, affecting the engine’s performance. Electronic issues, wiring problems or sensor failure may contribute to the malfunctioning EGR valve.

Vacuum Leaks

Many EGR systems rely on vacuum pressure to operate. However, the valves won’t function correctly if the vacuum or EGR diaphragm leaks. You can detect vacuum leaks from the causes, including cracked hoses, loose connections or deteriorating diaphragms.

Mechanical Failure

EGR valves can experience wear and tear over time. The wear and tear occurs due to oil contamination or excessive heat. These can lead to damaged seals or sticking valves, causing failure in opening and closing.

Symptoms of a Failed EGR Valve

While these symptoms can indicate various common car issues, here are the symptoms of a failing EGR valve.

A rusted EGR valve
A corroded valve can show signs, such as a check engine light or unusual sounds from the car

Check Engine Light 

A malfunctioning EGR valve often triggers the check engine warning light on the car dashboard. The ECU detects the issue with software calibration that causes unusual opening and closing of the valve. After that, it causes the check engine light to illuminate.

Poor Engine Performance

A failed EGR valve can cause rough idling, stalling or hesitation during acceleration. It may also become a cause of sluggish acceleration. These performance shortages happen due to the malfunctioning EGR valve that causes a bad air-fuel ratio. 

More NOx Emissions

Since the engine won’t be at the best performance due to EGR valve failure, the engine temperature will soar. That said, it will produce NOx emissions and pollute the air. It is to be noted that nitrogen oxides are very hazardous to health.

Excessive Exhaust Smoke

With uncontrolled functioning of the valve, the intake manifold receives an uneven air-fuel mixture. You can see white, grey or black smoke coming out from the car. While it can be due to several other issues in cars, you can check what the different car exhaust smoke tells.

Knocking or Popping Sound

You should not ignore car sounds. These sounds tell about the car problems. That said, a malfunctioning EGR system causes a knocking or popping sound due to the carbon buildup in the engine. 

How to Fix an EGR Valve

A malfunctioning EGR valve causes multiple problems, such as poor performance or excessive emissions. For that reason, it is essential to fix it. Here’s how to fix it.

Troubleshooting Codes

Check the troubleshooting codes using an OBD scanner. If you receive the car diagnostic codes from P0400 to P0408 or P1403 to P1406, that means the EGR system is malfunctioning. These codes indicate the exhaust gas recirculation flow problems, such as excessive or insufficient flow or solenoid problems.

You must replace the EGR valves to reduce the emissions from the car

Steps to Replace the EGR Valves

After checking the codes from the OBD scanner, you can replace the failed EGR valves. Here are steps to replace it:

  • Remove the engine cover and remove the electric connections and cable on the valve
  • Inspect the EGR mounting surface since a failed system is a cause of carbon buildup or corrosion
  • Clean the mounting surface and supply port of the valve
  • Take a new EGR valve with the bolt holes and gasket
  • Fix the valve and fasten the screws according to the manufacturer’s recommendations
  • Connect the electric cables and connections
  • Use a car diagnostic scan tool to recalibrate the system and reset the check engine light.

You must recalibrate the system for accurate opening and closing of the valve to achieve better vehicle performance.


What Happens When the EGR Valve Goes Bad?

You can detect multiple symptoms of a failed EGR valve. For instance, poor engine performance, different car smoke, knocking sound, and higher engine temperature are due to the bad EGR valve. Moreover, a failed exhaust gas recirculation valve can be a reason behind car temperature gauge fluctuations.

CAN EGR be Cleaned?

Yes. You can follow the steps to clean the EGR valve. It is necessary to clean the EGR valve after the car achieves the 50,000 mileage mark. 

These were all the details about the EGR valve. You must ensure that the EGR valve is functioning properly when you buy a used car in the UAE. Besides, it can cause the car to start for a second and then die due to the uneven air-fuel ratio.

What Happens When You Put Diesel in a Petrol Car?

  • Wrong Fuel in Car Consequences
  • How to Fix Misfuelling Problem
  • FAQs

Petrol and diesel are the two types of most commonly used automotive fuels in the UAE. They have very different chemical compositions and cannot replace each other. The type of fuel used in a car helps the engine perform and impacts its longevity, preventing wear and tear. Owing to all these performance and longevity-related factors, a car should always be run on the correct fuel. 

That said, what happens when someone accidentally puts diesel in a petrol car or vice versa? To find out, let’s understand the consequences and precautions to take in case of incorrect refuelling.

What If You Put Diesel in a Petrol Car: Misfuelling and Its Impact on Engines

Exploring the diesel in petrol car consequences
Using the wrong fuel type can clog spark plugs and other key components

Whether you have filled diesel in a petrol car or vice versa, the consequences can be pretty serious. If the mistake isn’t rectified timely, it can lead to engine damage. Let’s find out more about the two misfuelling scenarios.

Diesel in Petrol Car Consequences

The very first thing to avoid misfuelling is noticing the size of the nozzle. The nozzle of a car’s petrol tank is noticeably smaller than a diesel dispenser’s nozzle. Nevertheless, in case a petrol car gets filled with diesel, the chances of mechanical damage start building up. Petrol is a much more refined form of fuel than diesel. It is ignited by a chain of reactions in spark plugs. 

If a petrol car is started with the wrong fuel in its tank, it can clog spark plugs and the fuel system. The fuel filters that are not meant for diesel’s greasy properties will be among the first few parts to be affected. Misfueling can also lead to car engine misfires. Misfiring is often followed by a heavy amount of discoloured car exhaust smoke, which can be a critical sign of engine damage.

Petrol in Diesel Car Consequences

Unlike petrol engine functioning, diesel engines work by compressing the fuel to ignite. The fuel is then pushed in to lubricate the critical internal components of a car’s engine compartment. However, in case of misfuelling, the problem starts here. If petrol is circulated throughout the integral parts of the diesel engine, it would be hard to get rid of it.

Since petrol has less viscosity and different chemical properties than diesel, the car’s performance becomes unstable. The most concerning part is that it takes time to show misfuelling signs in diesel cars. Consequently, by that time, black smoke would probably start blowing out through the car’s exhaust system, while its movement gets sluggishly.

Petrol in a Diesel Car or Vice Versa: How to Fix It

How to Fix Putting Diesel in a Petrol car
Here’s what to do if you put the wrong fuel in your car

It is important to handle the wrong fuel in car consequences with extreme care to prevent diesel contamination in a petrol car and vice versa. Here’s what you can do, depending on the misfuelling situation.

  • If the fuel tank is filled up with diesel for under 5% of its total capacity, fill up the rest with petrol and drive the vehicle normally. Diesel can mix with petrol and cause no harm in this case. That said, it is recommended to completely drain the diesel from the tank to avoid any fuel contamination risks.
  • In a case where the amount of diesel exceeds 5% of the tank’s capacity, do not crank the engine. Instead, call a roadside assistance company in the UAE. Get it towed to the nearest workshop. Make sure to follow these tips to safely tow a car. The diesel should be drained entirely. Make sure to drain while flushing the fuel tank. Once the wrong fuel is flushed and cleaned thoroughly, fill it up with petrol again and everything will be good to go.
  • However, in the case of having petrol in a diesel car tank, do not turn the engine on at all. Due to low viscosity, even a very low amount of petrol can cause serious problems to engine parts that are not meant to run on it.
  • The worst-case scenario would be realising the refuelling mistake after driving the car for some time. Stop the car immediately and turn the engine off. The car should be towed to the nearest workshop. Besides getting rid of the wrong fuel, get the fuel filter changed as a precautionary measure. 
  • To effectively tackle the misfuelling problem in a diesel car, clean the fuel lines as well as the injector. Go for a well-reviewed fuel injector cleaner available among a variety of other used car accessories and parts for sale in the UAE
  • Moreover, to avoid misfuelling incidents, make sure to be well aware of all the differences of a petrol vs diesel engine.

Signs of Wrong Fuel in a Car

Here are common symptoms of Diesel contamination in petrol car or vice versa

The sooner the misfuelling mistake is realised, the better. Watch out for these symptoms of putting the wrong fuel in a car

  • Engine Misfire: If you experience irregular engine firing or jerking during acceleration, it can be because of the wrong fuel type. It is mainly because of the disrupted combustion process. Engine misfiring is one of the key diesel in petrol car symptoms or vice versa.
  • Excessive Smoke: An unusual amount of smoke, especially dark or black exhaust. This is another common sign of using the wrong fuel in the car.
  • Loud Knocking Sound: An incorrect fuel running through the engine has a high impact on the combustion process. As a result, the engine would start producing a high knocking sound.
  • Difficulty Starting the Engine: Using the incorrect fuel can lead to difficulty starting the engine, as it affects the ignition process. This problem can also occur with a car that has not been used for months. Here are some useful tips for starting after a long time.
  • Engine Stalling or Loss of Power: Wrong fuel can also be one of the reasons why your car engine keeps stalling. Moreover, misfueling can result in a noticeable loss of power while driving, indicating a disruption in the fuel delivery system.


What happens if you put diesel in a petrol car?

If diesel is mistakenly added to a petrol car, it can lead to engine damage. Diesel, being less refined, can clog spark plugs and fuel filters while causing engine misfires. The visible sign of these problems is discoloured exhaust smoke.

What happens if you put petrol in a diesel car?

When petrol is added to a diesel car, the lighter viscosity of petrol can lead to unstable performance. Signs may not be immediately apparent, but over time, the engine may produce black smoke and the vehicle’s movement can become sluggish.

How far can you drive with petrol in a diesel car?

The answer is a definitive ‘no’. A diesel car should not be driven with petrol in its tank. It can cause severe damage to the car’s mechanical internals.

How much is the cost of repairing a misfuelled petrol vehicle?

The repairing cost of a misfuelled car may depend on its make and model, as well as the intensity of the damage. To get an estimate, you can head over to these popular car garages in Dubai or your respective emirate.

These were some of the potential misfuelling scenarios, entailing problems and their quick solutions. To avoid such costly mistakes, make sure to be aware of the common car fuel myths. 

Whether you are looking for a new or a used car for sale in the UAE, beware of its fueling, oiling and fluid requirements. Refer to the car owner’s manual for all the necessary instructions.
