Parts for your 2013 Suzuki Splash-Egr valve

2013 Suzuki Splash EGR valve: is it there, what it does, and how to look after it

Short answer: it depends on the engine. On a 2013 Suzuki Splash with the 1.0 (K10B) or 1.2 (K12B) petrol engine, there’s no separate EGR valve. On the 1.3 DDiS diesel (the Fiat/GM 1.3 Multijet), there is a cooled EGR valve and it’s a common service item.

Technical sources that support this split include: Suzuki’s Electronic Parts Catalogue for the Splash (RB), which lists no EGR assembly on K10B/K12B petrol variants but shows an EGR valve and cooler on the D13A/1.3 DDiS, Suzuki service literature for the K12B engine, which describes no external EGR system on petrol models, and diesel service data for the 1.3 Multijet/DDiS, which clearly specifies a cooled, electronically controlled EGR system. Independent datasets (Autodata/Bosch ESI wiring and emissions schematics) also only show an EGR circuit on the diesel variant.

Why no EGR on petrol Splash models? Those engines meet emissions targets using precise fuel control, a three-way catalytic converter, and variable valve timing that provides an “internal EGR” effect via valve overlap. That approach removes the need for a separate EGR valve and piping on the K-series petrol Splash.

If the Splash in question is the 1.3 DDiS diesel, the EGR valve is absolutely relevant. Its job is to feed a controlled amount of inert exhaust gas back into the intake to drop combustion temperatures and slash NOx. On the DDiS, that system includes an EGR cooler, the valve itself, a position sensor and ECU control. Around town driving in Aus and NZ can soot these parts up, which brings on rough running, flat spots, higher fuel use and the dreaded MIL with P0401/P0402-type codes.

As part of routine servicing, a workshop will often inspect EGR operation with a scan tool, check commanded vs actual EGR position, and look for intake soot build-up. If performance issues or codes are present, the tech may remove the valve and cooler for a proper clean, check the cooler for internal leaks, and ensure the EGR pipework and gaskets are sealed. Many DDiS owners opt for pre-emptive cleaning around 60–90,000 km if the car lives on short trips. After refit, an adaptation/learning routine via scan tool helps the ECU relearn EGR limits. Quality low-ash oil, good diesel and the occasional longer highway run all help keep soot in check. If the valve’s motor or position sensor is crook, replacement is the go, use OE-quality parts, new gaskets and observe torque specs. It’s also smart to confirm there are no software updates pending, and to check related items like the MAP sensor and intake manifold for contamination so new parts don’t get fouled straight away. Avoid blanking plates—besides being illegal for road use in AU/NZ, they can upset DPF management and put the car into limp mode.

• Common diesel EGR symptoms: MIL on, limp mode, chuggy idle, black smoke, higher fuel burn.
• Good habits: regular highway stints, timely oil and filter changes, periodic intake/EGR inspection.
• After work: run EGR adaptation, clear codes, verify live data and take a proper road test.

Popular questions

Does my 2013 Suzuki Splash have an EGR valve?
Petrol 1.0/1.2 models generally don’t have a separate EGR valve. The 1.3 DDiS diesel does have one, plus an EGR cooler. To confirm, check the engine code (D13A means diesel) or look for the metal EGR pipe and cooler near the rear of the engine under the bonnet.

What are the signs of a failing EGR on the 1.3 DDiS Splash?
Expect a check engine light, reduced power or limp mode, uneven idle, and sometimes black smoke. Scan tools often show P0401 (insufficient flow) or P0402 (excessive flow). Cleaning or replacing the valve and checking the cooler and intake usually sorts it.

Can the EGR be blanked or deleted on a Splash diesel?
Not legally for road use in Australia or New Zealand. It can cause emissions failures, calibration issues, DPF troubles, and may void rego or insurance. Repairing or cleaning the system is the right play for a reliable, legal fix.
