Skoda Octavia vs Vauxhall Astra: which is the better used buy?
On DVSA MOT records the Skoda Octavia is the more reliable used buy: it passes its first MOT 3.3 percentage points more often than the Vauxhall Astra once both are compared against what the national fleet scores at the same age. That comparison covers 83,050 real tests, not a survey.

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.

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.

Vauxhall Astra
Mk7 / K (2015-2021) · A C-segment family hatchback (with an Astra Sports Tourer estate variant), sold in the UK against rivals such as the Ford Focus, VW Golf and SEAT Leon.
The Vauxhall Astra Mk7 (K), sold in the UK from 2015 to 2021, is an affordable, roomy family hatchback whose reliability depends heavily on which engine and build year you buy, not least because Vauxhall's 2019 facelift (under new parent company PSA) swapped in different engines and infotainment. On pre-facelift 2015-2018 cars, the single most important check is the timing chain: both the 1.4-litre turbo petrol and 1.6-litre CDTi diesel are chain-driven rather than belt-driven, and both are well documented for tensioner wear and cold-start rattle from roughly 50,000-90,000 miles, a fault that can cause serious engine damage if ignored, so listen carefully for rattle on a cold start and ask for any chain/tensioner history. Pre-facelift diesel buyers should also budget for EGR valve and DPF attention if the car has mostly done short urban trips, while manual pre-facelift 1.4 Turbo petrol cars are known for premature clutch and dual-mass flywheel wear. For the best balance of reliability and remaining life, target a 2020-2021 post-facelift example, which arrives after the range's four safety recalls and largely uses newer 1.2-litre turbo petrol or 1.5-litre diesel engines and a Multimedia Navi Pro infotainment system in place of the earlier units, sidestepping most of the specific issues above; the earliest 2016-2017 cars carry the highest risk of the old engines' teething problems and warrant the most cautious inspection.
What goes wrong
- Clutch & dual-mass flywheel wear (1.4 Turbo petrol, manual, pre-facelift)majorSlipping clutch, a high or vague biting point, and difficulty selecting gears. A small number of cars have also been reported with the clutch pedal sticking to the floor after being pressed, and owners have separately reported a buzzing/vibration noise from the clutch slave cylinder pipe, most noticeable around 3,000-3,500rpm.2016-2019 (1.4 Turbo petrol, manual gearbox) · Premature dual-mass flywheel and clutch wear is typically reported from around 40,000-60,000 miles, though isolated cases of much earlier clutch failure have appeared on owner forums, so don't assume low mileage rules it out. · Roughly £500-£900 for a clutch kit and dual-mass flywheel replacement at an independent garageCheck: Test drive uphill and in stop-start traffic: feel for clutch slip under load, a biting point that has crept high, or notchy gear selection. Listen for buzzing/vibration from the transmission tunnel around 3,000rpm, and ask whether the clutch pedal has ever stuck down.
- Timing chain wear (1.4 Turbo petrol)criticalA rattling or tapping noise from the engine on cold start-up that fades once oil pressure builds, caused by a stretched timing chain or worn tensioner/guides. In more advanced cases a chain guide can crack, and if ignored the chain can eventually jump timing and cause serious engine damage.2016-2019 (1.4 Turbo petrol) · Cold-start rattle is most commonly reported from around 50,000-70,000 miles onward, although a handful of much lower-mileage cases have also been reported. · Around £600-£1,200 depending on how accessible the chain is, more if a broken guide or tensioner has caused secondary damageCheck: Start the engine from cold, ideally with the bonnet up, and listen for a rattle in the first few seconds that quietens as oil pressure builds. Ask for any evidence of chain, tensioner or guide work in the service history.
- Timing chain tensioner failure (1.6 CDTi diesel)criticalA persistent rattle on every cold start caused by a tensioner design that lacks a gasket, letting oil drain out overnight; the resulting daily rattle gradually stretches and wears the chain. Left unaddressed, this can progress to the chain jumping timing or, in the worst case, snapping.2015-2018 (1.6 CDTi diesel) · Rattle typically starts to appear from around 60,000-90,000 miles, and can progress to a genuine chain failure risk beyond 100,000 miles if it's never investigated. · Roughly £800-£1,500 or more for a chain and tensioner replacement; substantially higher if the engine has suffered internal damage from a jumped or broken chainCheck: Listen for a rattle on cold start that's present every single morning rather than a one-off noise. Ask specifically whether the timing chain and tensioner have been replaced, and treat a high-mileage 1.6 CDTi with no record of this work with caution.
- EGR valve and DPF clogging (1.6 CDTi diesel)majorEngine warning light, reduced power or 'limp mode', rough idle, and DPF warning lights. Caused by soot building up in the EGR valve, which in turn accelerates clogging of the diesel particulate filter — especially on cars used mainly for short, low-speed journeys that never let the DPF regenerate properly.2015-2018 (1.6 CDTi diesel) · Can occur at almost any mileage on a car used mostly for short urban trips, but is most commonly flagged from around 40,000 miles onward on cars without regular motorway or dual-carriageway use. · Around £150-£400 to clean or replace the EGR valve; £700-£1,500+ for a replacement DPF if the filter itself has been allowed to blockCheck: Check the dashboard for any current or recently-cleared DPF or engine warning lights, ask about the car's typical journey type, and look through the service history for any EGR- or DPF-related work.
- Typical asking price:
- 2015–2016 1.4/1.6 CDTi: £5,000–£7,500 | 2017–2019 1.0/1.2 Turbo: £7,500–£11,500 | 2020–2021 facelift SRi/Elite Nav: £11,000–£15,500
- Real-world economy:
- 1.0 Turbo (105PS): 44–49 mpg. 1.2 Turbo: 42–47 mpg. 1.6 CDTi diesel: 55–62 mpg. 1.4 Turbo SRi: 38–43 mpg.

Which one suits you
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.
Vauxhall Astra
Good for: Buyers wanting a roomy, well-priced family hatch with genuinely low running costs on the smaller turbo petrols. The 2020–2021 facelift is the best-resolved version.
Less good for: Anyone considering the 1.4 Turbo SRi without confirmed timing-chain service history, or an early 2015–2016 car with a patchy record — both carry the highest risk of an expensive fault.
