Verdict

Buy with care

Compact rated 5 stars by Euro NCAP in 2012, with no recurring serious faults according to Caradisiac, but well-documented wear-related defects: cracked headlights and tail lights before the facelift, oil consumption of the 1.4 TSI, and a DSG 7 gearbox to watch. A Takata airbag recall targeted the Leon III: check it by serial number.

Which version to choose

Versions to favour: 1.0 TSI 115, 2.0 TDI 150.

  • 1.2 TSI 110

    Petrol · Manual · 110 hp · Crit'Air 1

    1.2 TSI with 110 hp (175 Nm), 6-speed manual gearbox: the entry-level petrol at the end of the series.

  • 1.2 TSI 110 DSG7

    Petrol · Automatic · 110 hp · Crit'Air 1

    The same 1.2 TSI with 110 hp and 7-speed DSG gearbox, to be tested at length (see the DSG 7 fault).

  • 1.0 TSI 115

    ✓ Recommended

    Petrol · Manual · 115 hp · 4.8 L/100 km · 107 g CO₂/km · Crit'Air 1

    1.0 TSI with 115 hp, introduced with the 2017 facelift. A used-car guide recommends the manual gearbox, which is simpler in the long term.

    Engine: Volkswagen 1.0 TSI (EA211)

    Verdict on this engine: Excellent choice

  • 1.4 TSI 125

    Petrol · Manual · 125 hp · Crit'Air 1

    1.4 TSI with 125 hp and 200 Nm. Monitor the oil level: oil consumption of the 1.4 TSI is reported.

  • 1.4 TSI 150 ACT DSG7

    Petrol · Automatic · 150 hp · Crit'Air 1

    1.4 TSI with 150 hp and cylinder deactivation (ACT), tested with the 7-speed DSG gearbox.

  • 1.5 TSI 150 ACT DSG7

    Petrol · Automatic · 150 hp · Crit'Air 1

    1.5 TSI with 150 hp and cylinder deactivation (ACT), DSG. One owner finds it less lively and less economical than the former 1.4 TSI ACT.

    Engine: Volkswagen 1.5 TSI / eTSI (EA211 evo)

    Verdict on this engine: Excellent choice

  • 1.6 TDI 110

    Diesel · Manual · 110 hp · Crit'Air 2

    1.6 TDI with 110 hp, 6-speed manual gearbox (250 Nm).

  • 2.0 TDI 150

    ✓ Recommended

    Diesel · Manual · 150 hp · Crit'Air 2

    2.0 TDI with 150 hp, 320 Nm, 6-speed manual gearbox. A used-car guide places it among the most consistent choices of the Leon 3, but a poor candidate for city driving.

  • 1.5 TGI 130 GNV

    Petrol · Manual · 130 hp · Crit'Air 1

    1.5 TGI with 130 hp, 200 Nm, running on compressed natural gas (CNG) with a small backup petrol tank. Launched in France in early 2019; the L'argus listing gives a manual gearbox, the Flotauto test a 7-speed DSG.

Known faults

Dry-clutch DSG 7 (DQ200): mechatronics and clutch

Severity 2/3 · Costly

The DQ200 7-speed dry-clutch DSG is known for low-speed jerks and premature clutch wear in intensive urban use, with fragile mechatronics (hydraulic and control unit). Careco advises against the DQ200 on Leon III models built before summer 2014. These sources are general guides on the gearbox and parts blogs: check the car's gearbox type and its maintenance history.

Worn dual-mass flywheel on the 2.0 TDI 150

Severity 2/3 · Costly

Fiches-auto states that the 2.0 TDI 150 can wear its dual-mass flywheel prematurely, with rattling or vibration; Carverif places the flywheel wear at around 80,000-120,000 km. Watch for vibration at idle, rattling when the ignition is switched off, and knocking on acceleration.

Cracked headlights and tail lights, condensation in the headlamps (before facelift)

Severity 1/3 · Annoying

Used-car guides cite cracked front headlights and rear lights, sometimes without any identifiable impact, on Leon III models before the 2017 facelift, as well as condensation in the headlamps. Owners report cracks in the plastic body; one guide advises checking the condition of the headlights before buying. No manufacturer recall was found for this fault.

1.4 TSI oil consumption

Severity 1/3 · Annoying

Caradisiac reports heavy oil consumption on the 1.4 TSI, especially during the first 20,000 km, which requires topping up the level between services; Careco also describes it as documented, sometimes from the first kilometres. Owner opinions on the 125 hp are divided: some describe consumption limited to the first kilometres, others around 1 litre per 10,000 km.

Recall: Takata airbags (Leon and Toledo)

Manufacturer recall

A recall campaign (internal reference 69EC) targets Leons fitted with Takata airbags; according to Car-recalls.eu, the affected Leons were built between June 2012 and September 2017, while Caradisiac cites Leons and Toledos assembled in 2013, 2014 and 2015. Only the serial number shows whether a given car is affected.

Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

Manufacturer recalls

See the official list on RappelConso (new tab) (French government recall site: category “Automobiles et moyens de déplacement”, search “Seat Leon”). A dealer for the brand can also check, using the vehicle identification number (VIN), that recalls have been carried out.

⚠ Estimates to treat with caution

  • NEDC consumption (older, more optimistic than WLTP) as no WLTP figure is published: fuel is probably slightly underestimated.
  • Maintenance: published servicing price plus an estimated allowance for tyres and brakes.
  • Depreciation estimated at 12% of the median price a year, as no year-by-year valuation is usable.
Calculation details (12,000 km a year)
Fuel (petrol)€118

1.0 TSI 115 version: combined consumption of 4.8 L/100 km, increased by 15% for real-world driving, at 2.14 €/L, for 1,000 km a month.

4.8 × 1.15 × 2.14 € × 10 = €118

Inspection checklist

Things to check

  • Have a Seat dealer check, using the serial number, the Takata airbag recall campaign (69EC).
  • Before the facelift (2012-2017): check the condition of the front headlights and rear lights (cracks, condensation).
  • 1.4 TSI: check the oil level before and after the test drive, and ask for the oil change invoices.
  • DSG 7: extended low-speed test drive in town to detect jerks and shuddering, and ask whether the clutch or the mechatronics have been replaced.
  • 2.0 TDI 150: listen for vibration at idle, rattling when the ignition is switched off and knocking on acceleration (dual-mass flywheel).

Questions to ask the seller

  • Has the Takata airbag recall been checked and carried out using the serial number?
  • What type of gearbox is fitted, and have the clutch or the mechatronics already been replaced?
  • For the 1.4 TSI: does the car consume oil, and which oils were used at the oil changes?

Test-drive tip: read the fault codes

A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.

Before you buy: check and equip

Check the history

Before paying, check the administrative status (lien, objection, declared claims) and the mileage recorded at the roadworthiness test.

Read fault codes

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.

Parts and maintenance

Compare prices of parts for the Seat Leon III (timing, brakes, filters) to estimate the repairs to plan for.

Insure the car

Insurance prices vary widely from one model to another: get a quote before signing.
