Parts for your 1999 Daihatsu Gran move-Egr valve

1999 Daihatsu Gran Move EGR Valve — Is it fitted and does it matter?

For Australian and New Zealand–market 1999 Daihatsu Gran Move models (petrol), an EGR valve isn’t fitted. Technical references that cover the Gran Move/Pyzar platform — including the factory workshop manual emissions section for G303/G313 models, the Daihatsu electronic parts catalogue (EPC) for AU/NZ region lookups, and the under‑bonnet vacuum hose routing label — list no EGR components on the HC‑EJ (1.5) or HD‑EP (1.6) engines supplied to these markets. These sources note EGR only on certain market calibrations, not on Australasian deliveries.

Why no EGR on this car? In 1999, the Gran Move’s local emissions compliance (ADR aligned to Euro 2 at the time) could be met with a three‑way catalytic converter, closed‑loop oxygen sensor control, precise ignition timing, and a well‑tuned combustion chamber — without needing exhaust gas recirculation. Deleting EGR reduces hardware complexity and vacuum plumbing, which suits the simple, robust design brief of this little MPV.

Owners chasing EGR parts for a 1999 Gran Move in AU/NZ typically don’t need them, because there’s nothing to replace. Instead, if the goal is to keep NOx down and drivability up, attention is better spent on the emissions system it does have:

• Keep the oxygen sensor healthy and replace it at high kilometres if fuel economy or idle quality drops.
• Ensure the catalytic converter isn’t restricted, a tired cat raises NOx and hurts power.
• Service the PCV valve and hoses to maintain stable idle and crankcase ventilation.
• Fix vacuum leaks, maintain ignition components (plugs, leads, coil), and use quality fuel.

If a Gran Move has been imported from a market that did use EGR, the intake will show a dedicated EGR passage and valve body mounted to the manifold, plus extra vacuum or electrical control. Australasian cars generally won’t have those bosses or lines, which is a quick way to confirm what’s fitted under the bonnet.

Popular questions

How can someone tell if their 1999 Gran Move actually has an EGR valve?

Look at the intake manifold for a metal valve with a round diaphragm top (vacuum type) or a small electronic unit plumbed to the exhaust via a steel pipe. AU/NZ petrol cars usually lack the mounting pad and pipework entirely, and the vacuum hose routing label won’t show an EGR circuit.

Will a missing or faulty EGR cause a check engine light on this model?

On AU/NZ petrol Gran Moves, there’s no EGR strategy to monitor, so there’s no EGR‑related fault to log. If a MIL is on, it’ll more likely be from an oxygen sensor, coolant temp sensor, misfire, or evap issue.

What maintenance best reduces NOx and keeps emissions tidy without EGR?

Regular servicing with fresh spark plugs, a clean air filter, no vacuum leaks, and a responsive oxygen sensor helps the ECU hold stoichiometric fuelling. A healthy catalytic converter then does the heavy lifting to keep NOx in check.
