Parts for your 2018 Suzuki Splash-Egr valve

Does a 2018 Suzuki Splash have an EGR valve?

Short answer: if the 2018-registered Suzuki Splash is a petrol (K10B 1.0 or K12B 1.2), an external EGR valve isn’t fitted or relevant. If it’s the 1.3 DDiS (Fiat Multijet) diesel, it does have an EGR system. The Splash ended production globally around 2014, but many were first registered later in New Zealand and Australia as used imports—hence “2018” on the rego doesn’t change the hardware.

This call is based on technical sources that map out emissions hardware by engine:

• Suzuki Splash/Ritz petrol (K10B/K12B) service literature: Emission Control System shows three‑way catalytic converter, VVT and EVAP, with no external EGR circuit.
• Suzuki electronic parts catalog (RB/RZ chassis, Euro 4/5): lists EGR valve/cooler assemblies only for the 1.3 DDiS diesel, not for K10B/K12B petrol variants.
• Fiat 1.3 Multijet (D13A/DDiS) technical description: specifies a cooled EGR system to meet NOx targets on lean-burn diesel operation.

Why petrol Splash models don’t use an EGR valve: modern Suzuki petrol engines run near-stoichiometric with a three‑way cat, precise ignition and cam phasing (VVT). That combo handles NOx effectively without the extra plumbing, cost and soot management an external EGR adds. Diesels, by contrast, run lean and generate more NOx, so they rely on EGR (often cooled) to meet Euro emissions rules.

What owners should do: check the engine code. If it’s K10B/K12B, there’s no external EGR to service—focus on clean oil, fresh plugs, good fuel and keeping the intake/throttle body tidy. If it’s the DDiS diesel, the car does have EGR, short-trip driving can soot it up, so occasional longer runs and quality fuel help keep it happier. When in doubt, a quick visual check works too: diesel EGR systems usually have a metal pipe and a cooler linking the exhaust manifold to the intake with an electric valve mounted nearby.

• Does my 2018 Suzuki Splash have an EGR valve?
  If it’s a petrol K10B or K12B, no. If it’s the 1.3 DDiS diesel, yes.
• How can I confirm which engine I’ve got?
  Check the VIN plate/registration details for the engine code, or look for the EGR cooler/pipework under the bonnet on diesels.
• What maintenance applies if mine is the diesel?
  Keep up with servicing, use decent fuel, give it regular highway runs, and clean or replace the EGR if fault codes or drivability issues appear.

Popular questions

Does my 2018 Suzuki Splash have an EGR valve?
Most NZ/AU 2018‑registered Splash cars are petrol K10B/K12B and don’t have an external EGR valve. Diesel DDiS versions do. A quick check of the engine code or a look for the EGR cooler and metal pipework between the exhaust and intake will confirm it.

How can I tell my engine code without pulling things apart?
The engine code is usually printed on the VIN/build plate and listed on rego papers. K10B/K12B means petrol (no external EGR). D13A/DDiS means diesel (has EGR). A scan tool on a petrol Splash also won’t show an EGR monitor, which is another hint.

What should be serviced if my Splash is the diesel with EGR?
Stick to oil and filter changes, use good-quality fuel, and do periodic longer drives to help manage soot. If you notice rough idle, limp mode, or codes like P0401/P0402, have the EGR and intake assessed for cleaning or replacement. Always run a proper diagnostic before swapping parts.
