The Peugeot 308 often faces issues during its MOT, with the most frequent failures being related to lights, brakes, and suspension components. Addressing these problems can vary in cost, but understanding the common faults can help owners prepare for their MOT and budget for necessary repairs.

Common Light Failures

One of the most prevalent reasons for MOT failure in the Peugeot 308 is lighting issues. This includes faulty headlights, brake lights, and indicators.

Regularly checking and replacing bulbs can prevent these issues. Owners should also ensure that all lights are functioning correctly before the MOT. If a light fails during the test, it can lead to an immediate failure, requiring a retest after repairs.

Brake System Issues

The braking system is critical for safety and is closely scrutinised during the MOT. Common failures in the Peugeot 308 include worn brake pads, discs, and issues with the brake fluid.

It is advisable to have the braking system inspected regularly, especially if there are signs of wear, such as squeaking noises or reduced braking performance. Addressing these issues early can save on more extensive repairs later.

Suspension Component Failures

Suspension problems are another frequent cause of MOT failures for the Peugeot 308. Issues often arise from worn shock absorbers, springs, or bushes.

A well-maintained suspension system is vital for handling and ride comfort. Owners should look out for signs like excessive bouncing or uneven tyre wear, which can indicate suspension issues that may need addressing before the MOT.

Exhaust System Problems

The exhaust system is essential for emissions control and is thoroughly checked during the MOT. Common issues include leaks, rust, and failed catalytic converters.

Regular checks of the exhaust system can help identify problems early. Owners should listen for unusual noises or check for visible rust, which can indicate that repairs may be needed before the MOT.

Tyre Condition and Tread Depth

Tyres are another critical area assessed during the MOT. The legal minimum tread depth in the UK is 1.6mm, and many Peugeot 308 owners fail due to insufficient tread or damaged tyres.

Maintaining proper tyre pressure and regularly checking tread depth can help avoid MOT failures. Owners should also inspect tyres for any visible damage, such as cuts or bulges, which can lead to immediate failure during the test.

Emissions Testing Failures

With increasing environmental regulations, emissions testing has become more stringent. The Peugeot 308 may fail its MOT if it exceeds the allowable emissions limits. Common causes include faulty oxygen sensors or issues with the engine management system.

Regular servicing and maintenance can help ensure that the emissions system is functioning correctly. Owners should pay attention to warning lights on the dashboard, as these can indicate potential issues that may lead to MOT failures.

Peugeot 308 recall record

59 recalls have been issued for the Peugeot 308, between 2008 and 2026.

  1. VSM software Interior door handles

    R/2026/228

    Issued 3 June 2026

    Affected vehicles may experience an unexpected deactivation of the interior door handles when the key is in engine-running mode which could result in occupants being unable to exit.

    Remedy:Update the Vehicle Supervision Module software.

    Affects cars built Nov 2023 to Feb 2026

  2. VSM software missing AEB telltale in case of blind camera.

    R/2025/542

    Issued 21 April 2026

    On certain Peugeot vehicles the Automatic Emergency Braking Assist telltale fails to illuminate if the front camera is blocked. No AEB warning telltale meaning no warning light appears in the instrument cluster. An additional pop-up appears for around 10 seconds at each key on/key off (Driving Assistance Sensor Blind: clean sensor see User Manual). The Automatic Emergency Braking system is operating in a degraded mode but remains functional due to radar support.

    Remedy:To rectify this issue we will update the Vehicle System Management software

    Affects cars built Feb 2024 to Jul 2024

  3. Peugeot Cross carline Fuel Injection common rail.

    R/2026/020

    Issued 21 January 2026

    On affected vehicles a non-conformity issue with the fuel injection common rail may lead to a loosening of the nut and a potential fuel leak.

    Remedy:Check the fuel injection common rail and if necessary replace the rail and high-pressure fuel pipes.

    Affects cars built Aug 2025 to Oct 2025

  4. Emission recall – On Board Diagnostics

    R/2025/344

    Issued 18 August 2025

    Vehicles may be affected by incorrect performance of the On-Board-Diagnostics related to Selective Catalytic Reduction system and/or Diesel Particle Filter. The Malfunction Indicator Light (MIL) may not illuminate in the event of a malfunction and therefore does not comply with emission regulations.

    Remedy:Update the Engine Control Unit software to ensure compliance to regulations.

    Affects cars built Oct 2016 to May 2021
