PEUGEOT 407 Common Problems & Reliability

Based on 699 MOT tests from 38 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every PEUGEOT 407 has the same fault.

PEUGEOT 407's have a average reliability rating of 485/999. The score was calculated from the average of every PEUGEOT 407 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Also check BHP & performance, road tax, fuel economy, and CO2 emissions for the PEUGEOT 407.

Common PEUGEOT 407 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore MOT data includes 197 advisory comments and 4 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: NEARSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Lamp and bulb faults

VehicleScore MOT data includes 50 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a lamp or bulb other than a headlamp or indicator.

What to inspect

Switch on the side, brake, fog, and number-plate lamps.

Example MOT wording: ANTI-LOCK BRAKING SYSTEM WARNING LAMP INDICATES AN ABS FAULT (1.6 (B))

Brake disc wear

VehicleScore MOT data includes 32 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: NEARSIDE REAR BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Oil leak

VehicleScore MOT data includes 17 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.

What to inspect

Look under the engine for fresh oil, and check the oil level.

Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))

Ball joint wear

VehicleScore MOT data includes 14 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a worn or damaged ball joint. Track rod ends are counted with steering, not here.

What to inspect

Ask for the joint to be checked for play with the suspension loaded and unloaded.

Example MOT wording: NEARSIDE FRONT SUSPENSION HAS EXCESSIVE PLAY IN A LOWER SUSPENSION BALL JOINT (2.5.B.1A)

Brake pad wear

VehicleScore MOT data includes 13 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Ask for recent pad replacement and look at the remaining pad thickness.

Example MOT wording: FRONT BRAKE PAD(S) WEARING THIN (3.5.1G)

Parking brake faults

VehicleScore MOT data includes 5 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a parking brake that did not hold well enough or had a component defect.

What to inspect

Test that the parking brake holds the car on a slope and releases cleanly.

Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))

Engine warning lamp

VehicleScore MOT data includes 4 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record an engine warning lamp that was on, or did not work, during the inspection.

What to inspect

Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

Example MOT wording: ENGINE MIL INOPERATIVE OR INDICATES A MALFUNCTION (8.2.1.2 (H))

PEUGEOT 407 MOT reliability by year

A model year is only commented on when VehicleScore has at least 5 vehicles from that year.

Year	Vehicles	MOT tests	Pass rate	Recurring issues seen
2008	6	113	71.7%	Tyre wear, Headlamp faults
2007	5	116	70.7%	Tyre wear, Brake disc wear
2005	5	112	67.9%	Lamp and bulb faults, Brake disc wear

What to check when buying a used PEUGEOT 407

This is an inspection checklist based on MOT comments in the VehicleScore sample. It does not mean the car you are looking at has these defects.

Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Lamp and bulb faults. Switch on the side, brake, fog, and number-plate lamps.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Ball joint wear. Ask for the joint to be checked for play with the suspension loaded and unloaded.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.
Engine warning lamp. Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

Buying a PEUGEOT 407?

Common problems tell you what can affect PEUGEOT 407s generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
