Parts for your 2017 Suzuki Splash-Egr valve

2017 Suzuki Splash EGR valve — is it actually a thing?

Short answer: for the 2017-registered Suzuki Splash most commonly seen in Australia and New Zealand with the 1.2‑litre K12B petrol engine, there isn’t an external EGR (exhaust gas recirculation) valve fitted, so an “EGR valve” isn’t a service item on these cars. This is backed by technical references including:

• Suzuki Electronic Parts Catalogue (Splash/Agila, K12B petrol): no EGR valve or cooler listed, EGR components only appear on the 1.3 DDiS (D13A/Fiat Multijet) diesel.
• Suzuki K12B workshop/service literature (emissions section): notes stoichiometric operation with three‑way catalyst and VVT, and no external EGR circuit on K‑series petrol engines.
• Autodata and Bosch ESI[tronic] component-location data: EGR shown for D13A diesel variants, not for K12B petrol.

Why no EGR on the 1.2 petrol Splash? The K12B meets emissions targets using a three‑way catalytic converter, closed‑loop fuelling and variable valve timing. That VVT strategy creates “internal EGR” by overlapping valve timing to control combustion temperatures and NOx, so there’s no need to add a separate EGR valve and cooler. On a small, high‑tumble petrol like the K12B, an external EGR can hurt idle stability and drivability, add weight and complexity, and deliver little emissions benefit at stoichiometric air‑fuel ratios—so Suzuki wisely left it out.

A quick note for edge cases: some markets had a 1.3 DDiS (D13A) diesel Splash. That engine does use an EGR valve and cooler, and those parts can soot up over time. If your Splash is a diesel import, you do have an EGR system to maintain, if it’s the common K12B petrol in AU/NZ, you don’t.

Practical takeaways under the bonnet for the petrol Splash:

• No EGR valve to replace or clean on K12B petrol models.
• Keep emissions happy by servicing the PCV valve, cleaning the throttle body, using quality fuel, and replacing oxygen sensors when they age.
• If you’re unsure which engine you’ve got, check the build plate (engine code K12B vs D13A) or ask a workshop to confirm.

Does a 2017 Suzuki Splash have an EGR valve?

On the 1.2 K12B petrol model, no—there’s no external EGR valve fitted. On the rarer 1.3 DDiS diesel import, yes—there’s an EGR valve and cooler. Most AU/NZ Splashes are petrol, so an “EGR valve” isn’t relevant to regular servicing for those cars.

How can someone confirm whether their Splash has an EGR system?

Check the engine code on the identification plate or registration details: K12B = petrol, usually no EGR valve, D13A/DDiS = diesel with EGR. A visual check also helps—diesels have an EGR valve and cooler assembly at the rear/side of the engine with metal coolant lines and a small radiator-like cooler.

If there’s no EGR on the petrol Splash, what emissions maintenance still matters?

Plenty: keep the PCV valve clean, service the air filter on time, clean the throttle body if idle gets rough, and monitor oxygen sensors and the catalytic converter health. High‑quality fuel and regular long runs help keep the catalyst and injectors in good nick.
