Parts for your 2013 Holden Commodore-Egr valve

2013 Holden Commodore EGR Valve — Is It Fitted or Needed?

For the Australian and New Zealand–delivered 2013 Holden Commodore range, an external EGR (exhaust gas recirculation) valve is not fitted and isn’t used. Factory engines for that model year — the 3.0L/3.6L SIDI V6 (LFW/LFX) and 6.0L V8 (L77) — meet emissions targets without external EGR hardware, so there’s no EGR valve to service or replace on these cars.

Technical sources back this up. Holden/GM Service Information (SI) for VE Series II MY12–MY13 and early VF (carry-over engines) lists “Exhaust Gas Recirculation — Not Used” within Engine Controls for both the LFX V6 and L77 V8. The Holden Electronic Parts Catalogue (EPC) for 2013 VE/VF shows no EGR valve, pipes, or cooler for these engines. GM powertrain documentation for the LFX V6 also notes emissions control via continuously variable cam phasing, precise fuel control, and three‑way catalysts — strategies that negate the need for an external EGR system.

Why the 2013 Commodore does without an EGR valve:

• Engines use variable cam timing to create an “internal EGR” effect, trimming NOx without extra plumbing.
• ADR 79/02–79/03 compliance is achieved using cam phasing, catalytic converters, and tight fuel/ignition control.
• Simpler packaging and fewer soot/soak issues than an external EGR circuit on these petrol engines.

If a listing online shows an “EGR valve” for a 2013 Commodore, it’s typically a generic catalogue artefact or meant for different Holden models (like Cruze diesels) or much later imported Commodore variants. Likewise, if a scan tool throws generic EGR‑type fault codes on a 2013 Commodore, it’s worth rechecking the engine selection in the tool. For drivability or emissions faults on these cars, technicians usually look at PCV function, MAF readings, intake leaks, oxygen sensor operation, catalytic converter efficiency, and ECM software updates — not an EGR valve that isn’t there.

Popular questions

Where is the EGR valve on a 2013 Holden Commodore?
It isn’t fitted. The 2013 models with LFW/LFX V6 or L77 V8 engines don’t use an external EGR system, so there’s no valve to find under the bonnet.

Why do some parts sites list an EGR valve for this car?
Many catalogues are generic across models and markets. Those EGR listings usually apply to different Holdens (like Cruze diesels) or non‑Commodore applications, not a 2013 Aussie‑built Commodore.

Getting EGR‑style fault codes — what should be checked instead?
Confirm the scan tool is set to the correct engine. On these cars, common checks include MAF accuracy, PCV operation, intake manifold gasket leaks, oxygen sensor health, catalytic converter efficiency, and ECU calibration updates.
