Peugeot 508 years to avoid? MOT pass rate by year

14,651 initial MOT tests in 2025 on cars first used 2011–2021 · DVSA data · For guidance only · How we count

Peugeot 508 years with MOT pass rates below the average for vehicles first used in the same year: 2013 and 2019–2021. None is clearly above it. The other 3 years can't be told apart from average.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

70.1%passed first time

First-time pass rate, all years together: initial tests passed with no repairs. 95% range 69.3% to 70.8%.

In 2025, 70.1% of the 14,651 initial MOT tests on Peugeot 508 cars were passed with no repairs. The same-age average, for all vehicles first used in the same years, was 71.8%. That is 1.7 points below the same-age average.

Peugeot 508 MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

Common 508 problems at the MOT

Share of the 4,384 failed tests with a fault in each area, all years together. A test can count in more than one area, so these add up to more than 100%.

MOT records show roadworthiness faults, not engine or gearbox problems. Each year page compares that year's failure areas with all vehicles first used in the same year.

What to check when viewing a 508

Based on the areas where Peugeot 508 MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

  1. Lights and electrics

    In 33.5% of failed 508 tests

    • Ask the seller to help you check every light: dipped and main beam, brake lights, indicators, fog lights and the number plate lamp.
    • Look for cracked, misted or yellowed headlight lenses.
    • Warning lights on the dashboard should come on with the ignition and go out once the engine starts.

  2. Suspension

    In 28.5% of failed 508 tests

    • Push down hard on each corner. The car should rise once and settle, not keep bouncing.
    • On the test drive, listen for knocks or clunks over speed bumps and potholes.
    • The car should sit level when parked on flat ground.

  3. Tyres

    In 27.9% of failed 508 tests

    • Check the tread on every tyre. The legal minimum for cars is 1.6 mm across the central three-quarters of the tread.
    • Look for cuts, bulges, and wear on only the inner or outer edge, which can point to an alignment problem.
    • Check that the spare wheel or the tyre repair kit is there.

  4. Brakes

    In 21.0% of failed 508 tests

    • On a clear road, brake firmly. The car should stop in a straight line without juddering or pulling to one side.
    • Check the handbrake holds the car on a slope.
    • Look through the wheels at the brake discs for deep grooves or a raised lip at the edge.

Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.

Tyres

Of Peugeot 508 cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 10.1% failed on tyres, against 6.7% of similar cars with nothing noted. Based on 2,150 and 6,938 cars.

  • With a tyre advisory10.1%
  • Similar cars, nothing noted6.7%

Cars not tested again in that window are not included: 15.9% of those with a tyre advisory and 15.0% of the others.

Brakes

Of Peugeot 508 cars that passed their 2024 MOT with a brake advisory and came back for their next MOT 10–14 months later, 9.3% failed on brakes, against 5.2% of similar cars with nothing noted. Based on 1,762 and 7,351 cars.

  • With a brake advisory9.3%
  • Similar cars, nothing noted5.2%

Cars not tested again in that window are not included: 16.4% of those with a brake advisory and 14.9% of the others.

Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.

An MOT checks safety and emissions on the day of the test. It doesn't measure breakdowns, engine or gearbox faults, or repair costs.

What are the most common Peugeot 508 problems at the MOT?

The most common failure areas are lights and electrics (in 33.5% of failed tests), suspension (in 28.5% of failed tests) and tyres (in 27.9% of failed tests). A failed test can count in more than one area.

What mileage is normal for a 5-year-old Peugeot 508?

How do I check a specific 508's MOT history?

Enter its registration in our free check. It lists that car's own MOT results, the faults and advisories recorded and the mileage at each test, and flags repeated advisories and mileage that goes down.

What MOT data can't tell you about any Peugeot 508

Outstanding finance, write-offs, theft and plate changes aren't in MOT records. For a particular car, you need a history check.
