Parts for your 2016 Holden Commodore-Egr valve

2016 Holden Commodore EGR Valve — Is It Fitted or Relevant?

According to Holden’s VF Commodore Workshop Manual (2013–2017) and General Motors Service Information for the 3.0L RPO LFW and 3.6L RPO LFX V6 engines, as well as the 6.2L RPO LS3 V8, the 2016 Holden Commodore is not fitted with an external EGR (exhaust gas recirculation) valve. These technical sources list no EGR valve in the engine controls or emissions hardware for these petrol engines. GM’s documentation for the Gen IV LS-family similarly notes that external EGR is not used on LS3 applications.

Why no EGR valve on a 2016 Commodore? The VF Series II petrol engines achieve emissions compliance (Euro 5/ADR 79/04) using a mix of precise fuel control, close-coupled catalytic converters and variable valve timing. The cam phasing strategy provides “internal EGR” by overlapping valve events to reintroduce a controlled amount of exhaust gas back into the cylinders, removing the need for a separate EGR valve and plumbing. This approach simplifies the hardware, reduces potential failure points and keeps the intake tract cleaner than a traditional EGR system might.

Engines offered for 2016 include:

• 3.0L SIDI V6 (LFW) — no external EGR valve
• 3.6L SIDI V6 (LFX) — no external EGR valve
• 6.2L LS3 V8 — no external EGR valve
• Factory LPG variants (where fitted) — no external EGR valve listed

For owners searching “2016-holden-commodore egr-valve”, it’s worth knowing there isn’t an EGR valve to replace or maintain on these models. If the car’s showing rough idle, pinging, or emissions-related warnings, the cause will be elsewhere — think dirty throttle body, MAF sensor issues, vacuum leaks, ageing spark plugs or coils, or carbon build-up on intake valves common to direct-injection V6s. Good servicing practice focuses on quality engine oil and filters, periodic throttle body and MAF cleaning, software updates, and fuel of suitable octane. If chasing a suspected “EGR fault”, a technician will instead scan for codes, smoke-test for leaks and inspect PCV and intake systems under the bonnet.

Bottom line: a 2016 Holden Commodore doesn’t use a separate EGR valve, by design. It meets its emissions targets through internal strategies and robust catalytic after-treatment, so there’s nothing labelled “EGR valve” to service or swap on this model year.

FAQs — 2016 Holden Commodore EGR Valve

Does a 2016 Holden Commodore have an EGR valve?
No. Technical references including the Holden VF Commodore Workshop Manual and GM Service Information for the LFW, LFX and LS3 engines show no external EGR valve is fitted. These engines rely on cam phasing and catalytic converters to manage emissions.

Where would the EGR valve be located on a 2016 Commodore?
It isn’t present. If a parts listing suggests one, it’s a generic catalogue carry-over. Under the bonnet you won’t find an EGR valve or EGR cooler on these petrol engines, the intake and exhaust manifolds lack the usual EGR piping and flange points.

What causes rough idle if there’s no EGR valve to clog?
Common culprits are a dirty throttle body, contaminated MAF sensor, intake or PCV vacuum leaks, carbon on intake valves (on direct-injection V6s), or tired plugs and coils. A scan for fault codes and a basic air-intake check usually points a technician in the right direction.
