Parts for your 2020 Suzuki Splash-Egr valve

Is an EGR valve used on a 2020-registered Suzuki Splash?

Short answer: on the petrol Splash, no. On the diesel Splash (DDiS), yes. While Suzuki ended Splash production globally mid‑decade, plenty were first registered later, so a “2020 Suzuki Splash” will still be running the original 1.0 K10B or 1.2 K12B petrol, or the 1.3 DDiS diesel powertrain from the 2008–2014 era.

Referencing technical sources used by workshops—Suzuki Global Service/Workshop information for the Splash/RS platform and K‑series engine technical notes, plus OE parts catalogues and diesel service data—the common petrol Splash engines (K10B/K12B) are not shown with an external EGR valve or cooler. Their emissions strategy relies on a three‑way catalytic converter and engine management (including valve timing/overlap on applicable variants) to achieve the internal EGR effect needed to control NOx. In contrast, the 1.3 DDiS (Fiat Multijet) diesel is documented with an electronically controlled EGR valve and an EGR cooler assembly as part of its Euro emissions package.

Why the difference? On modern port‑injected petrol engines like the Splash’s K‑series, external EGR hardware isn’t required to meet emissions targets, internal dilution via cam timing plus the three‑way cat does the heavy lifting. This keeps the petrol setup simpler, lighter, and less prone to soot‑related issues. Diesel combustion produces more NOx under lean conditions, so the DDiS uses cooled EGR to reduce peak combustion temperatures and meet standards.

• Petrol Splash (K10B/K12B): no external EGR valve fitted.
• Diesel Splash (1.3 DDiS/Multijet): EGR valve and cooler fitted.

If someone’s chasing an “EGR valve” for a 2020‑registered Splash that’s petrol, it’s not a service item because it’s not there. For diesel owners, the EGR lives near the intake with a metal cooler linking to the exhaust—common symptoms when it clogs include rough idle, limp mode and codes like P0401/P0402. Routine inspection/cleaning around 60–80,000 km (sooner for short‑trip city use) helps keep it sweet.

How to tell which one it is? Check the build plate or rego papers for the engine code. K10B/K12B = petrol, no EGR valve. D13A/DDiS = diesel with EGR fitted.

• Popular questions about 2020 Suzuki Splash EGR valves

Does a 2020‑registered Suzuki Splash have an EGR valve?
For the common petrol K10B and K12B Splash, there’s no external EGR valve, emissions are handled by engine management and the three‑way catalytic converter. Only the 1.3 DDiS diesel variant uses an EGR system with a valve and cooler.

How can someone confirm if their Splash is the diesel DDiS with EGR?
Check the engine code on the build plate or rego papers—D13A/DDiS indicates the 1.3 diesel. Visually, the diesel shows a high‑pressure fuel rail and an EGR cooler with metal pipes running from the exhaust side to the intake near the throttle body.

What maintenance applies if the Splash is the diesel with EGR?
Plan periodic inspection and cleaning of the EGR valve and cooler every 60–80,000 km, sooner for lots of short trips. Tell‑tales of a blocked EGR include rough idle, hesitation, excess smoke and EGR‑related fault codes (often P0401/P0402).
