2016 Subaru XV EGR valve: what’s fitted and what owners should know

For the 2016 Subaru XV sold in Australia and New Zealand with the 2.0i petrol FB20 engine, there isn’t an external EGR (exhaust gas recirculation) valve fitted. That’s per Subaru technical literature for the FB-series engine used in Impreza/XV of this era, which lists the emissions hardware as evaporative control, PCV and (on some specs) secondary air injection—no external EGR valve. Subaru’s FB engine training materials also explain that variable valve timing (i‑AVCS) is used to create “internal EGR” on petrol engines, making a separate EGR valve unnecessary. EPA/Certification component listings for the 2016 Crosstrek/Impreza FB20 likewise show no EGR component for the 2.0L petrol.

Why no EGR valve on the 2.0i XV? On a spark‑ignition Subaru FB20, NOx emissions are primarily handled by running stoichiometric mixtures and the three‑way catalytic converter. Subaru’s i‑AVCS cam timing strategy leaves a small amount of spent gas in the cylinders (internal EGR) to lower combustion temperature and knock tendency—achieving the benefits EGR is known for without the complexity of an external valve and cooler. That’s why there’s no EGR valve to service or replace on the 2016 XV 2.0i.

There is one important exception: markets that received the XV with the 2.0D EE20 turbo‑diesel do use an external, cooled EGR system (with an EGR valve and EGR cooler), as shown in Subaru’s EE20 diesel service manuals and repair procedures. If the vehicle is a diesel XV, EGR inspection and periodic cleaning are part of normal fault diagnosis when dealing with soot‑related drivability issues.

For owners of the Australian and New Zealand 2016 XV 2.0i, chasing an “EGR valve” part or replacement usually points to a red herring. Rough idle, pinging, or emissions‑related fault codes are more commonly tied to items the FB20 actually has: dirty throttle body, sticking PCV valve, intake manifold deposits, sluggish O2/AFR sensors, or secondary air injection faults (where fitted). A sensible servicing plan is:

• Regular oil and filter changes to limit intake deposits.
• Periodic throttle body and intake duct clean, and PCV check/replacement.
• Genuine-spec spark plugs at the correct interval.
• Scan for ECU updates and address any stored DTCs promptly.

• Does a 2016 Subaru XV 2.0i have an EGR valve?
  For the AU/NZ 2.0i petrol FB20, no external EGR valve is fitted. Emissions control relies on i‑AVCS internal EGR, the three‑way catalytic converter, evaporative control and PCV (and secondary air injection on some specs).
• Where is the EGR valve located on a 2016 XV petrol?
  There isn’t one on the FB20. If someone is chasing rough running or a CEL thinking it’s “EGR”, start with throttle body cleanliness, PCV function, intake leaks, O2/AFR sensors and software updates.
• What about a diesel XV of the same year?
  The 2.0D EE20 diesel variant (offered in some markets) does use a cooled EGR system with a serviceable EGR valve and cooler. Soot build‑up can require cleaning or replacement per Subaru diesel service procedures.
