Parts for your 2009 Suzuki Splash-Egr valve

2009 Suzuki Splash EGR valve – what’s actually fitted

For the 2009 Suzuki Splash, whether there’s an EGR (exhaust gas recirculation) valve depends on the engine. The common 1.0 K10B and 1.2 K12B petrol variants are not fitted with an external EGR valve. These K‑series petrol engines meet emissions using precise fuelling, a three‑way catalytic converter, and variable valve timing to create internal EGR via valve overlap. By contrast, the 1.3 DDiS diesel (Fiat/Multijet family) does use an electronically controlled EGR valve with a cooler to control NOx.

Technical sources that note this split include: Suzuki K‑series petrol service information showing no external EGR circuit, Opel/GM TIS documentation for the sister model (Agila B) petrol engines with no EGR hardware, Bosch Automotive Handbook guidance that small Euro‑4 petrol engines often delete external EGR when VVT and a three‑way cat are used, Fiat/Suzuki workshop material for the 1.3 Multijet/DDiS indicating a cooled, electronically actuated EGR system.

Why petrol Splash models skip an EGR valve: on stoichiometric petrol engines with a three‑way catalytic converter, external EGR offers limited additional NOx benefit versus internal EGR achieved by cam timing. Deleting the valve removes a potential failure point, simplifies the vacuum/plumbing layout, and still meets Euro‑4/5 when combined with VVT and closed‑loop control.

When fitted (1.3 DDiS diesel), the EGR valve sits between the exhaust manifold and intake, often paired with an EGR cooler. Its job is to meter a measured portion of exhaust back into the intake to lower combustion temperatures and cut NOx emissions. Over time, soot and oil vapour can build up, causing sticky operation, rough idle, smoke on acceleration, poor fuel economy, or limp‑home with fault codes like P0400–P0409. As part of regular servicing, it’s smart to inspect and, if needed, clean the EGR valve and adjacent intake tract around 60,000–80,000 km, especially if the car mainly does short trips. Use new gaskets on refit, check the cooler for leaks or clogging, and confirm the actuator moves freely. After refitting or replacing, a scan tool can run an EGR actuation test and perform any required relearn, clearing codes without verifying movement won’t fix a sticking valve.

Choosing replacement parts? Go for quality OE‑equivalent valves with the correct connector and mounting pattern for the DDiS. Mixing coolers and valves from other Multijet applications can cause fitment or calibration headaches. To help keep the system cleaner for longer, run good diesel, stick to low‑ash oil to protect the DPF, and give the car an occasional longer run so the exhaust sees proper temperature. Avoid blanking plates or software deletes, they’re illegal for road use in AU/NZ and can trigger other engine and DPF issues.

Popular questions

Does a 2009 Suzuki Splash 1.2 petrol have an EGR valve?
No. The 1.0 K10B and 1.2 K12B petrol Splash engines don’t use an external EGR valve. Emissions are handled with VVT‑based internal EGR and a three‑way cat, so there’s no EGR to replace or service on those petrol variants.

Where is the EGR valve on a 2009 Splash 1.3 DDiS?
On the DDiS diesel, the EGR valve is mounted near the rear/side of the engine, linking the exhaust to the intake via an EGR cooler. Access varies by market layout, but it’s typically reachable from above once the engine cover and some intake plumbing are removed.

Can the EGR on a DDiS be cleaned or should it be replaced?
If the valve isn’t electrically failed, a careful clean of the valve and nearby passages can restore smooth operation. If the actuator or position sensor is faulty, replacement is the go. Always use new gaskets and check the cooler for restrictions when you’re in there.
