Hyundai i30 vs Skoda Octavia: which is the better used buy?
On DVSA MOT records the Skoda Octavia is the more reliable used buy: it passes its first MOT 6.2 percentage points more often than the Hyundai i30 once both are compared against what the national fleet scores at the same age. That comparison covers 31,450 real tests, not a survey.
MOT first-time pass rate
Counted from DVSA’s anonymised MOT test records. “vs age-matched” compares each model against what the national fleet scores at the same age — the only fair better-or-worse number, because an older fleet fails more whatever its build quality.
| Model | Pass rate | Age-matched national | Difference | Tests |
|---|---|---|---|---|
| Hyundai i30 | 71.2% | 75% | -3.8 | 10,713 |
| Skoda Octavia | 80.5% | 78.1% | +2.4 | 20,737 |

Hyundai i30
PD, 2017+ · compact family hatch
The PD Hyundai i30 (2017+) is one of the most reliable compact hatches in the UK. The 1.4 T-GDI turbopetrol has documented oil-pressure and injector issues before the 2020 facelift; the diesel 1.6 CRDi is solid. DCT (dual-clutch) on 1.4 T-GDI judders in low-speed traffic. Best-buy: 2020+ 1.6 CRDi or 1.0 T-GDI. Worst: 2018–2019 1.4 T-GDI DCT.
What goes wrong
- 1.4 T-GDI engine — oil pressure warningmajorOil pressure warning light on startup; engine noise at idle; low oil level despite no visible leak2018–2019 1.4 T-GDI (before ECU calibration update) · ECU update free under warranty; if engine damage occurred: £2,500–£5,000Check: Dipstick at viewing — check level and colour. Ask if oil pressure warning has ever been triggered. Service history must show Hyundai-stamp oil changes at 6,200 miles or 12-month intervals (whichever comes first). Avoid 1.4 T-GDI without confirmed ECU update.
- 7-speed DCT judder (1.4 T-GDI)moderateShudder when pulling away from a standstill in traffic; hesitation at low speeds; occasional "clunk" engaging Drive from neutral2017–2019 DCT variants · DCT software update free at Hyundai dealer; fluid change £150–£220; mechatronic fault £800–£1,500Check: Test drive in heavy stop-start urban conditions — not just an open road. DCT should engage cleanly. Any shudder requires DCT software check and fluid condition inspection.
- 1.6 CRDi diesel — DPF (short-trip urban)moderate"DPF regenerating" warning; limp mode; reduced powerAll 1.6 CRDi diesel variants · Usage-pattern-driven · £350–£650 forced regen; £1,400–£2,200 DPF replacementCheck: Ask seller about typical journey length. CRDi used exclusively for sub-6 miles school runs is a red flag. Avoid without evidence of regular 30-minute motorway runs.
- TPMS sensor faultsminorTyre pressure warning despite correct inflation; sensor unresponsive after tyre changeAll PD i30 · £80–£130 per sensorCheck: Check TPMS warning light on dash during inspection.
- Typical asking price:
- £7,000–£20,000 (2017–2023) (note i30 N Performance can exceed this)
- Real-world economy:
- 1.4 T-GDI: 36–44 mpg. 1.0 T-GDI: 39–47 mpg. 1.6 CRDi: 49–59 mpg
- Vehicle tax:
- £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
- Best years:
- 2020, 2021, 2022, 2023
- Years to avoid:
- 2018, 2019
Skoda Octavia
Mk4, 2020+ · compact family hatch and estate (saloon-shaped hatch)
The Mk4 Skoda Octavia (2020+) shares the VW Golf Mk8 platform — including its early infotainment software bugs (resolved in 2023+ updates). The eTSI 48V mild-hybrid starter generator has occasional faults, and DSG DQ381 is well-sorted. Best-buy: 2023+. Worst: 2020–2022 infotainment.
What goes wrong

Which one suits you
Hyundai i30
Good for: UK families wanting a reliable, well-equipped compact hatch backed by Hyundai's 5-year warranty. The 1.6 CRDi diesel is the sweet spot for long-distance commuters; the 1.0 T-GDI for urban and suburban use.
Less good for: Buyers considering a pre-2020 1.4 T-GDI DCT without oil-pressure ECU update evidence; short-trip-only diesel buyers.
Skoda Octavia
Good for: Practical family buyers wanting Golf substance with Skoda value — bigger boot, lower price.
Less good for: Buyers without tolerance for early Mk4 infotainment quirks.
