Renault Clio vs Volkswagen Polo: which is the better used buy?

On DVSA MOT records the Volkswagen Polo is the more reliable used buy: it passes its first MOT 8.8 percentage points more often than the Renault Clio once both are compared against what the national fleet scores at the same age. That comparison covers 98,625 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.

Renault Clio

Mk4 2012–2019, Mk5 2019+ · supermini hatchback

The Renault Clio is one of the UK's most popular superminis. The Mk4 (2012–2019) is reliable but has a known timing belt replacement requirement on 1.5 dCi diesel engines and documented EGR valve fouling. The Mk5 (2019+) with the 1.0 TCe turbopetrol and optional mild hybrid is significantly more modern and reliable overall. Key concerns: EDC dual-clutch gearbox reliability on Mk4, clutch wear on manual diesels, and infotainment updates needed on early Mk5. Best buy: 2021+ Mk5 1.0 TCe manual. Worst: Mk4 with high-mileage diesel and EDC auto.

What goes wrong

Timing belt — 1.5 dCi diesel (Mk4)critical
No warning — belt fails without symptoms; catastrophic engine damage results
Mk4 2012–2019 (1.5 dCi diesel) · Replace every 35,000 miles or 5 years · £400–£650 preventative kit; £2,000–£4,000 engine if belt snaps
Check: Verify belt change in service history. The Renault 1.5 dCi is an interference engine. No record means budget for immediate replacement before buying.
EDC dual-clutch gearbox judder (Mk4)major
Shudder from standstill; hesitant 1st-to-2nd change; jerky slow-speed behaviour
Mk4 2012–2019 (EDC automatic) · Often from 25,000 miles on; worsens with age · £300–£800 re-learn and fluid change; £1,500–£2,800 mechatronic or replacement
Check: Test at walking pace in traffic and from cold. The Mk4 EDC is the weakest part of the car. If buying automatic Mk4, only accept a price that reflects the gearbox risk. Mk4 manual is far more reliable.
EGR valve fouling (1.5 dCi diesel)moderate
Engine Management Light; rough idle; black smoke under acceleration; loss of power
Mk4 2012–2019 (diesel) · Above 50,000 miles or heavy short-journey use · £350–£700 EGR clean or replacement
Check: Check EML during test drive. Diesels with service history showing mostly city driving are highest risk. An Italian tune (hard motorway run) before the test can mask symptoms temporarily.
Infotainment software (Mk5 early build)minor
MediaNav or Easy Link screen freezes; CarPlay drops out; slow wake from standby
2019–2021 Mk5 · £0 — dealer software update resolves most cases
Check: Test CarPlay and navigation responsiveness during test drive. Renault dealer OTA update is free. If freezing occurs, request update as a condition of sale.

Typical asking price:: Mk4: £2,000–£9,000 | Mk5: £5,000–£17,000 (2019–2023)
Real-world economy:: 46–54 mpg (1.0 TCe petrol, real-world UK); 51–63 mpg (1.5 dCi diesel)
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).

Volkswagen Polo

Mk6 AW (2017–present) · B-segment supermini. Consistently one of the top 5 best-selling used cars in the UK. The Mk6 Polo brought Golf-like interior quality to the supermini segment. Available with 1.0 MPI (naturally aspirated), 1.0 TSI (turbocharged), and 1.6 TDI diesel engines.

The VW Polo Mk6 is a premium-feeling supermini with solid reliability when maintained. The 1.0 TSI petrol is the engine to choose — reliable, tax-friendly, and economical. The main concern on Mk6 Polos is the timing chain on early 1.0 TSI engines (pre-2019), which can stretch if oil changes are delayed. The 7-speed DSG dual-clutch automatic has judder issues in urban use above 30,000 miles. Avoid the 1.6 TDI diesel for city use (DPF). A well-maintained 2019+ Polo 1.0 TSI manual is one of the safest sub-£20,000 used superminis on the UK market.

What goes wrong

1.0 TSI timing chain stretch (early production)critical
Chain rattle on cold start; engine warning light (timing-related codes); rough running; in severe cases, engine failure
2017–2018 (1.0 TSI 95 and 115 PS) · From 35,000 miles if oil changes were delayed; can appear earlier with incorrect oil specification · £600–£1,500 timing chain kit; up to £4,000+ if engine damage has occurred
Check: Listen for chain rattle on cold start (first 10 seconds). Check the oil change history — the 1.0 TSI requires oil changes every 9,300 miles or 12 months maximum (not 20,000 miles longlife intervals). Longlife oil change intervals are a major risk factor. Ask if the chain has been replaced or inspected. On 2017–2018 cars specifically, ask for proof of oil change compliance.
7-speed DSG dual-clutch juddermajor
Shudder when moving off from standstill; jerkiness at low speed in traffic; clutch grab in 1st gear
2017–2022 (7-speed DQ200 DSG automatic) · Above 30,000 miles in urban use; earlier if no DSG service has been carried out · £400–£700 DSG fluid and filter service + software recalibration; £1,500–£3,000 if mechatronic unit or clutch pack needs replacement
Check: Test the DSG at walking pace in slow traffic and pulling away from a standstill on an uphill. Any shudder is the known DQ200 judder — very common on Polo, Golf, and other VAG models with this gearbox. VW schedules no oil service for the dry-clutch DQ200, so absent DSG fluid records are normal rather than a red flag; a voluntary mechatronic oil service (some specialists suggest around 60,000 miles) can ease mild judder. Severe judder at low mileage without service history is a red flag.
Infotainment MIB2 system freeze and Bluetooth issuesminor
Touchscreen freezes or goes blank; Bluetooth disconnects; screen reboot on startup
2017–2020 (MIB2 infotainment) · Not mileage-related — software issue · £0 — VW dealer software update resolves most issues; hardware replacement rare (£300–£600 if required)
Check: Test the touchscreen and Bluetooth during the test drive. MIB2 system freezes are resolved by a free dealer software update in most cases. Ask if the infotainment system has had the latest VW software applied.
AdBlue system faults (1.6 TDI diesel)minor
AdBlue warning light; countdown to engine start lockout; "Top up AdBlue" warnings
2017–2021 (1.6 TDI) · Every 9,300–10,000 miles (consumable — not a fault) · £15–£25 for 5L AdBlue top-up; £200–£600 if NOx sensor or SCR catalyst fails
Check: Check the AdBlue level if buying a TDI variant. AdBlue is a consumable — low warning is normal. However, NOx sensor failures are more common on higher-mileage TDI Polos. Check whether the engine management light is on.

Typical asking price:: Mk6 2017–2019: £6,000–£11,000 | Mk6 2020–2022: £9,000–£16,000
Real-world economy:: 44–51 mpg (1.0 TSI real-world UK mixed); 57–67 mpg (1.6 TDI real-world)
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:: 2019, 2020, 2021
Years to avoid:: 2017, 2018

Which one suits you

Renault Clio

Good for: First-time buyers and young drivers seeking low running costs. City and suburban driving. Buyers who want proven reliability on a small budget. Mk5 E-Tech hybrid for fuel economy.

Less good for: Buyers who need an automatic gearbox and want reliability — avoid the Mk4 EDC. Rural drivers who need more ground clearance. High-mileage diesel buyers doing short journeys.

Volkswagen Polo

Good for: Buyers who want Golf-level interior quality in a smaller package. Urban commuters who primarily use the car in town (1.0 TSI manual is ideal for this). Buyers who want strong resale value — VW Polos hold value well on the UK market.

Less good for: Buyers doing heavy city driving with the DSG automatic without a DSG service budget. 2017–2018 1.0 TSI buyers who cannot verify oil change compliance and chain condition. City-only drivers considering the 1.6 TDI — DPF issues are near-certain. Buyers who want the most reliable possible supermini should consider the Toyota Yaris Hybrid.

Which years should I avoid?

For the Renault Clio, Early Mk4 (2013–2015) UK examples suffer from EDC dual-clutch gearbox judder, EGR fouling on diesel, and 1.5 dCi timing belt neglect. These are the most problematic Clios to buy used. For the Volkswagen Polo, 2017–2018 launch cars had the highest incidence of 1.0 TSI timing chain stretch complaints — particularly where oil change intervals were extended or low-quality oil was used. DSG judder on early automatics was also more pronounced before software calibration updates.

Which is cheaper to run?

The Renault Clio returns 46–54 mpg (1.0 TCe petrol, real-world UK); 51–63 mpg (1.5 dCi diesel) in real UK driving; the Volkswagen Polo returns 44–51 mpg (1.0 TSI real-world UK mixed); 57–67 mpg (1.6 TDI real-world). Vehicle tax: Clio — £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).; Polo — £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).. Insurance differs mainly by driver and postcode rather than by model, so treat any model-level insurance figure with caution.
