Is it worth replacing an EGR valve?
A new EGR valve may improve performance by helping the engine to run more smoothly. It may also help to reduce emissions and improve overall fuel economy. The EGR system reduces harmful emissions by recirculating exhaust gases into the combustion chamber. But when the EGR cooler malfunctions, it can result in hot exhaust gas entering the cylinders, potentially causing engine damage and increased emissions.The cons of an EGR delete include the potential for potential fines (EGR deletes are illegal), decreased horsepower, increased exhaust gas temperatures, and increased chance of engine knocking and damage.Most diesel cars only go through a visible smoke test, so an EGR delete often doesn’t cause an MOT failure. However, future MOT rules may become stricter, increasing the risk of detection.In addition to the potential for engine damage, deleting the EGR system may also result in other issues. For example, some vehicles may experience reduced fuel efficiency without the EGR system, as the engine may not be able to run as efficiently without the recirculated exhaust gas.
What is the lifespan of an EGR valve?
You can even experience engine knock or detonation inside the combustion chamber, which damages the engine and will reduce its lifespan. Generally, an EGR valve has a lifespan of about 10 years or 100,000 miles, whichever comes first. Regular cleaning every 50,000 miles or so will extend that lifespan. If it malfunctions, your engine won’t run smoothly, leading to more fuel consumption and higher emissions. While you might be able to drive with a faulty EGR valve for a short time, getting it replaced at an auto repair shop can help you avoid severe engine performance issues down the road.If your vehicle has a faulty EGR valve, it might still be safe to drive for a short period, especially if the issue doesn’t significantly impact performance or safety. However, driving with a malfunctioning EGR valve can potentially affect your vehicle’s emissions, performance, and fuel efficiency over the long run.In general, it is a costly repair, and it can be a complicated task for the mechanic if for example the EGR valve is connected to the cooling system in the engine.If your EGR tube is dirty, cleaning it would solve most issues. However, if it’s damaged or there are other problems reducing its performance, it might be better to replace it.
Can I replace my EGR valve myself?
If you’ve never done an EGR valve replacement, have no fear. It’s a fairly straightforward job any DIY mechanic can tackle using a few basic hand tools. A faulty EGR valve causes rough idle, engine knocking, or increased emissions. Inspect the valve for carbon buildup or sticking. Cleaning may restore function, but replacement is needed if damage persists. Check related vacuum lines and sensors for leaks or faults.Ignoring a faulty EGR valve can lead to serious issues, including: Triggering the engine management light (EML). Reduced power and the car going into limp mode. Excessive carbon build-up in the intake manifold.Find the EGR valve and spray WD-40 or other penetrating solution onto the valve bolts. Wait a few minutes for it to work into the threads. Disconnect the vacuum tube running to the intake manifold and any electrical connectors. Check the condition of the vacuum line and inspect for cracking or dry rot.If you notice any of these signs, it might be time to replace your EGR valve: Poor engine performance — Rough idling, stalling, or reduced power. Higher emissions and fuel consumption — A faulty valve increases emissions and lowers fuel efficiency.Some EGR valves are easily accessible while others require a serious effort to get at them. Follow these steps for a general guideline on changing an EGR valve, and consult a service manual for more precise instructions for your own make and model.
How many hours does it take to replace an EGR valve?
An EGR valve replacement takes between 1 and 3 hours for most vehicles. However, this often varies depending on your vehicle, whether your chosen garage has the right part in stock and if there are any unforeseen complications. Is it a big job to replace an EGR valve? The complexity of replacing an EGR valve varies depending on several factors. These include the vehicle make and model, the location of the EGR valve, and the accessibility of the components surrounding it. Generally, it is considered a moderate-level repair.The average cost of replacing an EGR valve is £265, with prices ranging from £150 and £650. If the faulty EGR valve has caused increased emissions and overheating there is a possibility that it could have caused damage to associated components.A faulty EGR valve may seem like a minor problem, but it can cause significant damage to your vehicle, including engine damage, decreased fuel economy, and failed emission tests.Apply vacuum directly to the EGR valve using either a hand vacuum pump or scan tool depending on the type of EGR valve. If there is no change in idle quality, then either the EGR valve is faulty or the passages are completely restricted.
Can I clean an EGR valve without removing it?
Cleaning without removal can temporarily solve EGR issues, but it may not be as effective as complete removal and cleaning. If you continue to experience issues, or if the valve becomes severely clogged, it may be necessary to remove it for a more thorough cleaning or replacement. When the VW Transporter EGR valve becomes clogged with carbon deposits, it can lead to reduced engine performance, increased emissions, and poor fuel economy. You may also notice rough idling, engine misfiring, an illuminated check engine light, and sometimes the engine may even stall or fail to start at all.A malfunctioning EGR valve can lead to a noticeable decline in engine performance. You may experience a rough idle, hesitation, or stalling when starting your vehicle. Acceleration may feel sluggish, or you may notice a lack of power when driving uphill. Increased fuel consumption.The EGR valve may suffer various damages that affect its proper operation. One of the common problems is contamination of the valve, which may lead to its blockage or restriction of gas flow. Other potential damages are leaks, corrosion, damage to the diaphragm or solenoid valve.While you might still be able to drive with a bad EGR valve, it’s not recommended. Ignoring the issue can lead to further engine problems and increased emissions.
How long do VW EGR valves last?
EGR valves typically last between 50,000 to 100,000 miles but can fail due to factors such as carbon buildup, corrosion, mechanical wear, or electronic issues. Regular cleaning helps extend their lifespan, but replacement may be necessary if faults occur. EGR valves typically last between 50,000 to 100,000 miles but can fail due to factors such as carbon buildup, corrosion, mechanical wear, or electronic issues.

If you continue to experience issues, or if the valve becomes severely clogged, it may be necessary to remove it for a more thorough cleaning or replacement.On average, EGR valve replacement times can range from 1 hour to 3 hours with an average of 1. The time that the job takes will depend on a number of factors, like your vehicle’s make and model, year, as well as other factors.Being a simple valve that regulates exhaust gas flow, EGR valves work in a hot and dirty environment. They can clog with sooty deposits that prevent the valve from opening and closing. While cleaning may be an option, consider that a typical EGR valve lifespan is 70,000 miles.An EGR valve can fail when it loses vacuum, the diaphragm is perforated, it is full of gunk, or the valve gets stuck open. When this happens the EGR valve will need to be replaced.
