Parts for your 2009 Nissan Tiida-Egr valve

2009 Nissan Tiida EGR valve — is it even there?

For the 2009 Nissan Tiida sold in Australia and New Zealand, an external EGR (Exhaust Gas Recirculation) valve isn’t fitted on the common petrol engines. Nissan’s C11 Tiida factory service information for the MR18DE and HR16DE engines states the EGR system is “not used,” and the official Nissan FAST electronic parts catalogue for C11 petrol variants doesn’t list an EGR valve, pipe, or cooler assembly. Industry data from Autodata/Alldata for AU/NZ applications also records EGR as “not fitted” on these petrol models. That means an “egr-valve” isn’t a relevant service item on local 2009 Tiida petrol cars.

Why no EGR? Nissan engineered these Tiida petrol engines to meet ADR 79/02 (Euro 4) using internal EGR via CVTC (continuously variable valve timing), precise ignition and fuel control, and an efficient three‑way catalytic converter. By holding a controlled amount of spent gas in‑cylinder through valve timing, they get the NOx reduction benefits of EGR without the extra external valve, pipes and cooler. Fewer parts under the bonnet, fewer potential leaks, and simpler servicing.

Notes on sources:

• Nissan Tiida/Versa C11 Factory Service Manual (Engine Control System, MR18DE/HR16DE, 2007–2012): EGR system listed as “not used”.
• Nissan FAST Electronic Parts Catalogue (C11, MR18DE/HR16DE, AU/NZ market): no EGR valve or EGR tube part numbers for petrol variants.
• Autodata/Alldata AU/NZ application data for Tiida C11 petrol: EGR “not fitted”.

What this means for owners:

• There’s no EGR valve to clean or replace on AU/NZ 2009 Tiida petrol models.
• If a scan tool shows an EGR‑related fault, double‑check the engine/market spec, on petrol C11s that usually points to generic code mapping or another issue (e.g., MAF, throttle body deposits, vacuum leak, CVTC solenoid) rather than a missing EGR part.
• Rare grey‑import diesels can have EGR. If you’ve got a diesel Tiida (uncommon locally), inspect for an EGR cooler and metal pipe from the exhaust manifold to intake, or confirm by VIN/engine code.

Does a 2009 Nissan Tiida have an EGR valve?

On AU/NZ petrol models (MR18DE and HR16DE/HR15DE), no — there’s no external EGR valve fitted. A rare diesel import may be different, so check the engine code and look for an EGR cooler/pipe assembly at the back of the engine.

Why am I seeing an EGR fault code on my Tiida if there’s no EGR?

Generic OBD apps can label faults broadly. On petrol Tiidas, an “EGR”‑type code can actually relate to airflow or combustion control issues. Start with basics: check for intake leaks, clean the MAF and throttle body, verify PCV operation, and confirm the CVTC solenoid and timing are behaving. Use a scan tool with Nissan‑specific data PIDs if possible.

What emissions‑related servicing helps on a Tiida without EGR?

Stick to quality fuel, change the air filter and spark plugs on time, keep the MAF/throttle body clean, ensure the cooling system is in good nick, and fix any vacuum leaks. These steps keep NOx and HC under control and help the cat converter live a long life.
