Toyota Aygo common problems & fixes (Mk1 2005–2014, Mk2 2014–2022)

Written by the C4R team from DVSA data and owner reports. Fact-checked 2026-10-04.

The 30-second verdict

The Aygo is one of the cheapest cars to run in the UK and its little 1.0 three-cylinder is tough. Most faults are minor: clutch wear, water getting inside, and the odd water pump on older cars. The automated manual (MMT on Mk1, x-shift on Mk2) is jerky, so a manual is the better buy. The Aygo shares its basic design and engine with the Peugeot 107/108 and Citroën C1, so much of this guide applies to those too.

Generations at a glance

Known issues

1. Clutch wear

• Label: Reported by owners (multiple independent sources)
• What you notice: a high biting point, slipping under acceleration, judder pulling away, difficulty selecting gears.
• Years: most often earlier Mk1 cars; later cars received a stronger clutch.
• Why: light city use with lots of clutch slipping; some early clutches were on the weak side.
• Fix: clutch kit. Cost: £400–£700 (typical UK independent garage, 2026).
• DIY difficulty: 4/5.
• Check when buying: check the bite point, try a hill start, and ask if the clutch has been replaced.

2. Water leaks into the cabin and boot

• Label: Reported by owners
• What you notice: damp carpets, misting windows, a musty smell, water in the spare-wheel well.
• Why: door, tailgate and glass seals, and drains around the scuttle.
• Fix: reseal or replace seals, clear drains. Cost: £80–£300 (typical UK independent garage, 2026).
• DIY difficulty: 2/5.
• Check when buying: press the carpets in the footwells and lift the boot floor.

3. Water pump failure — older Mk1

• Label: Reported by owners
• What you notice: coolant leak or crust near the pump, whining, temperature rising.
• Fix: new water pump. Cost: £200–£400 (typical UK independent garage, 2026).

4. Jerky MMT / x-shift automated manual

• Label: Reported by owners
• What you notice: lurching changes, hesitation from a standstill.
• Fix: re-learn, actuator or clutch. Cost: £150–£900 depending on parts (typical UK independent garage, 2026).
• Check when buying: if you need an automatic, try one for a good while in traffic before you commit.

5. Exhaust and minor corrosion — older cars

• Label: Reported by owners
• What you notice: blowing exhaust, rust on rear sections and on body seams of older cars.
• Fix: exhaust section replacement. Cost: £100–£300 (typical UK independent garage, 2026).

Recalls

• Accelerator pedal (2010 campaign): pedals could stick partly down or return slowly, mainly in cold, damp conditions. The campaign covered Aygo, Peugeot 107 and Citroën C1 built between February 2005 and August 2009; Peugeot and Citroën's UK recalls focused on cars with ESP or the automated gearbox.
• Older Aygos may also be included in airbag campaigns — check the specific car.

MOT watch-points

What the 2024 DVSA figures say

• First-time pass rate: 75.7% from 261,740 normal Class 4 and 7 Toyota Aygo tests.
• National comparison: 71.5% across the same 2024 dataset, so this model was 4.2 percentage points above the national first-time pass rate.
• Typical tested mileage: median 44,571 miles; mean 50,809 miles.

Most common recorded failure reasons

One test can record more than one defect, so the shares must not be added together.

Common advisories to check before buying

• Tread depth: worn close to legal limit/worn on edge — recorded on 14.3% of tests.
• Tyres - condition: slightly damaged/cracking or perishing — recorded on 14.1% of tests.
• Brake discs: worn, pitted or scored, but not seriously weakened — recorded on 10.5% of tests.

Method and limits: C4R calculated these figures from DVSA's anonymised 2024 MOT results. Pass rate is P / (P + F + PRS) for normal Class 4 and 7 tests. Results are de-duplicated by test, low-volume rows are suppressed, and DVSA model labels are standardised into a model family. These figures describe tested cars as a group; they do not predict the condition of one vehicle or prove that every trim and generation performs the same way.

Pre-MOT checks worth doing: tyres, brake pipes and discs on older cars, exhaust, bulbs and wipers, and corrosion near suspension mounts.

Buying one? Our checklist

1. Check the clutch bite point and try a hill start.
2. Feel the carpets and lift the boot floor for damp.
3. Look for coolant crust near the water pump on older cars.
4. Prefer a manual over the automated manual.
5. Confirm the pedal recall on 2005–2009 cars.
6. Look under the car for exhaust and seam corrosion.
7. Check service history — cheap cars are often neglected.
8. Test the heater fan and demister (damp cars mist badly).
