Hyundai i30 PD Inspection Checklist

lowStart-stop (ISG) system playing up

Look for: The idle-stop system can become unreliable, often from a tired battery, a faulty battery sensor, or A/C control logic.

If you find it: Test/replace the battery and battery sensor; software update where applicable.

Any · ~$150-500

lowSunroof motor software recall (early i30 N)

Look for: Certain i30 N built around mid-2018 had incorrect sunroof-motor software that may not have had the automatic anti-pinch safety stop.

If you find it: Confirm recall campaign completion by VIN; dealer software fix.

Any · ~$0 under recall

lowFront brake / consumables wear

Look for: Brakes, tyres and front consumables wear normally with use; the i30 N in particular chews pads, rotors and tyres if driven hard.

If you find it: Quality pads/rotors; budget higher consumables on the N.

From 40k+ km (sooner on N) · ~$300-900

lowIntake carbon build-up (GDi)

Look for: Direct-injection (GDi) variants can accumulate carbon on the intake valves over time, causing slightly rough running or a small power/economy loss.

If you find it: Intake/walnut-blast clean if symptomatic; quality fuel and regular oil changes slow it.

From 100k+ km · ~$300-800

lowOil consumption on some examples

Look for: Some turbo-petrol examples use a little oil between services; left unchecked, low oil accelerates turbo and engine wear.

If you find it: Check oil between services; keep levels correct and to schedule.

From 80k+ km · ~$100-500 (monitoring)

lowIntake carbon and turbo/PCV issues

Look for: Direct injection causes intake-valve carbon, while EGR/PCV faults can add to carbon and pressure issues; the TD04 turbo suffers if oil is neglected.

If you find it: Intake clean if symptomatic, maintain PCV/EGR, and keep oil fresh to protect the turbo.

From 100k+ km · ~$400-1500
