Before you buy a used Peugeot 407.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.
The essentials.
- 3 documented, sourced faults across its 4 engines.
- 1 of them depends on the equipment or the production date: ask what this car has.
- 1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
- According to the data we have, the engines with the fewest documented faults are: 1.8 / 2.0 (atmosférico) (Petrol), 2.7 V6 HDi (Diesel).
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.

| 1.8 / 2.0 (atmosférico)PetrolFewest documented | 11 with conditions | 1 |
| 1.6 HDiDiesel | 21 with conditions | 0 |
| 2.0 HDiDiesel | 21 with conditions | 0 |
| 2.7 V6 HDiDieselFewest documented | 11 with conditions | 1 |
According to the data we have, the engines with the fewest documented faults are: 1.8 / 2.0 (atmosférico) (Petrol), 2.7 V6 HDi (Diesel).
By fuel type, the one with the fewest documented faults is: Petrol.
We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.
Official recalls: ask before you pay
A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Peugeot dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 3 checked
Turbo / injection
Look out for: Loud turbo whistle, power loss, blue or black smoke, oil that gets dirty very quickly. Before the failure, often a puffing or ticking from the cylinder head and an exhaust smell from an injector.
Ask them to check: Check injector bolt torque and carbon at their base, the turbo banjo bolt and the sump strainer.
DPF / EGR / turbo / flywheel
Look out for: Particulate filter warning and power loss; rough idle from a dirty EGR; vibration and knocks when starting or in low gears (dual-mass flywheel); smoke or hesitation from injectors at high mileage.
Ask them to check: Read the DPF status and additive level, check the EGR and cooler, check the dual-mass flywheel at start-up and measure injector balance rates.
Automatic gearbox
Look out for: The “Sport” and “Snow” lights flash together or “Gearbox fault” appears; very harsh shifts before the gearbox goes into limp mode in 3rd (only 3rd and reverse). It often happens when cold or after a few minutes' driving and clears after restarting the engine.
Ask them to check: Read the codes with PSA-compatible equipment (Diagbox/Lexia) and log line pressure while driving, especially when cold. Check fluid level and condition and, if changed, use the specified fluid and reset the wear counter. Also check the lever position switch.
