A pass rate is not a reliability score. The full Peugeot 508 MOT record has the pass rate by age, every common failure and how the 508 compares with similar cars.

Diesel made up 82% of Peugeot 508 MOT tests in 2025, against 39.3% across all models in this data. Almost every used example you look at will be a diesel.
Where the 508 fails its MOT
Where Peugeot 508 cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were tread depth below requirements of 1.6mm (8.7%), coil spring fractured or broken (6.4%) and brake pads less than 1.5 mm thick (5.4%). See every common 508 MOT failure.
These are DVSA failure records across every Peugeot 508 that failed, not a claim that every 508 has these problems.
What should you check when buying a used 508?
The areas above, most common first, and what an MOT tester looks at in each.
1
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 22.9% of 508 failure items.
2
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 18.7% of 508 failure items.
3
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 18.5% of 508 failure items.
4
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 15% of 508 failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 9.5% of 508 failure items.
None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.
What the MOT record doesn't tell you
Knowing Peugeot 508 failures cluster around lamps, reflectors and electrical equipment and suspension tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Peugeot 508 FAQs
Is the Peugeot 508 reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 71.2% first-time pass rate for the Peugeot 508 across 17,996 tests in 2025, below the 72.3% average for all cars.
Do older Peugeot 508 cars fail their MOT more often?
Peugeot 508 cars aged 3 to 5 years passed 81.2% of MOT tests in 2025; for examples aged 11 years and over that fell to 63.6%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used Peugeot 508?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, suspension and tyres. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check a Peugeot 508's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
