Parts for your 2021 Suzuki Splash-Egr valve

2021 Suzuki Splash EGR Valve — is it actually fitted?

Short answer: for most 2021-registered Suzuki Splash cars seen in Australia and New Zealand, an external EGR (exhaust gas recirculation) valve isn’t fitted or relevant. The common petrol Splash engines — the K10B 1.0 and K12B 1.2 — don’t use an external EGR valve. Only the 1.3 DDiS diesel (Fiat/GM 1.3 Multijet) version has an EGR valve and cooler. That diesel variant is uncommon in AU/NZ.

This conclusion aligns with technical sources including the Suzuki/Maruti Ritz (RB) service manuals and emissions diagrams, Suzuki Electronic Parts Catalog listings, and workshop data such as Haynes and Autodata. These show no external EGR system on the K-series petrol Splash, while the D13A/1.3 DDiS diesel is documented with an electronically controlled EGR valve and cooler assembly.

Why no EGR on the petrol Splash? The K-series engines meet their emissions targets using precise fuel control, variable valve timing, high-swirl/tumble intake design, a three-way catalytic converter, and oxygen-sensor feedback. They also leverage cam overlap for a bit of “internal EGR,” so an external EGR valve isn’t needed. Adding external EGR on small stoichiometric petrol engines can complicate control and may increase HC/CO if not tightly managed — Suzuki simply didn’t need it on these motors to pass Euro norms.

It’s also worth noting the Splash ended production years before 2021, so “2021” usually reflects first registration or import date. The actual engine spec remains the earlier RB-series Splash/Ritz mechanicals.

• K10B/K12B petrol Splash (most AU/NZ imports): No external EGR valve fitted.
• D13A 1.3 DDiS diesel Splash: EGR valve and cooler fitted from factory.

Servicing tip: if the car is the typical petrol Splash, there’s no EGR valve to replace or clean. Focus maintenance on fresh oil, quality fuel, air filtration, spark plugs, and keeping the throttle body and PCV system tidy. If it’s the diesel DDiS, EGR soot build-up is a known maintenance item, use correct diagnostics, follow the workshop manual procedure for cleaning or replacement, and ensure the EGR cooler and related vacuum/actuator controls are sound.

• Does a 2021 Suzuki Splash have an EGR valve?
  Most 2021-registered Splash cars in AU/NZ are petrol K10B or K12B and do not have an external EGR valve. Only the 1.3 DDiS diesel uses EGR.
• Which Splash engines use EGR?
  The D13A 1.3 DDiS diesel uses an electronically controlled EGR valve and cooler. The petrol K10B/K12B engines don’t.
• How can someone check if their Splash has EGR?
  Look for an alloy EGR valve and pipework linking the exhaust manifold to the intake, usually with a small cooler on diesels. If it’s a petrol K-series and there’s no such hardware, it doesn’t have external EGR.
