The Role of the EGR Valve in the 2016 Subaru Exiga and What to Know About Its Maintenance

The 2016 Subaru Exiga, a popular multi-purpose vehicle in markets that enjoy practical family cars, comes with a range of engine options depending on the region. When it comes to the EGR valve, or Exhaust Gas Recirculation valve, this particular car is fitted with one. The EGR valve plays a vital role in reducing nitrogen oxide emissions, improving fuel efficiency, and ensuring smoother engine operation, making it an important component for owners to understand.

To begin with, what exactly is an EGR valve and why is it important for vehicles like the Subaru Exiga? The EGR valve is a part of the vehicle's emissions control system. It works by recirculating a portion of the engine's exhaust gases back into the combustion chamber. This process lowers the combustion temperature, which helps to cut down on harmful nitrogen oxide (NOx) emissions produced by the engine during the combustion cycle. Lower NOx emissions not only mean the vehicle is more environmentally friendly but also ensures compliance with emission regulations.

For the 2016 Subaru Exiga, especially models equipped with its conventional petrol engines, the EGR valve is often found integrated into the intake manifold or the throttle body area. By redirecting exhaust gases, the EGR valve reduces the formation of nitrogen oxides without significantly compromising engine performance or fuel economy.

Living in Australia or other markets where emission standards are strictly enforced, maintaining a healthy EGR valve is part and parcel of keeping the 2016 Subaru Exiga running clean and efficiently. Over time, the exhaust gases can leave behind carbon deposits, leading to partial or full blockage of the valve. This buildup can cause the EGR valve to stick open or closed, resulting in a rough idle, reduced fuel efficiency, or a check engine light coming on.

When considering maintenance or replacement of the EGR valve on the 2016 Subaru Exiga, knowing the signs of failure is helpful. Common symptoms include:

• Rough engine idle or stalling after starting the car
• Reduced fuel economy, meaning more trips to the servo
• Increased engine knocking or pinging
• Check engine light illuminated, often showing fault codes related to the EGR system
• Failed emissions test during vehicle inspections

If any of these symptoms appear, it is a good idea to get the vehicle inspected by a technician familiar with Subaru engines. They will typically carry out visual inspections and might use diagnostic tools to check for EGR-related fault codes. In many cases, cleaning the valve is enough to restore good operation. Cleaning involves removing carbon deposits from the valve and the passages in the intake manifold. However, if the valve is stuck or damaged, replacement may be required.

It's worth noting that servicing the EGR valve is not an everyday job. Most Subaru experts recommend checking the valve around every 60,000 to 80,000 kilometres depending on driving conditions. Vehicles driven mainly on highways tend to accumulate less carbon build-up compared to those in urban stop-start traffic, where the EGR valve might need more frequent attention.

Replacement EGR valves for the 2016 Subaru Exiga are readily available from authorised Subaru dealers and various aftermarket suppliers. Genuine Subaru parts might be a little pricier but come with the assurance of fitment and quality. Ensuring the replacement part is a genuine or approved unit is recommended to avoid issues with compatibility or premature failure.

When the EGR valve is replaced or thoroughly cleaned, the vehicle's engine usually feels more responsive with better fuel economy and cleaner emissions. Many owners report smoother idling and a quieter running engine after this service.

All up, the EGR valve on the 2016 Subaru Exiga plays an important role in keeping the engine healthy and emissions down. Paying attention to its condition as part of regular service routines means fewer surprises, better fuel economy, and a cleaner-smelling exhaust. In effect, owning a Subaru Exiga with a well-maintained EGR valve means doing a little extra to keep the environment happy and your ride humming along nicely.
