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. A blown bulb is a simple fix, usually costing around £10 to £20 for parts and labour. However, if the problem lies in the wiring or the light unit itself, costs can escalate to £100 or more.

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. Replacing brake pads typically costs between £100 and £200, while disc replacement can range from £150 to £300 depending on the parts used.

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. Replacing shock absorbers can cost between £150 and £300, while spring replacements can be similar, depending on whether both front or rear springs need attention.

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. Repairing a simple exhaust leak may cost around £50 to £100, but replacing a catalytic converter can be significantly more expensive, often ranging from £300 to £800.

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. Replacing a single tyre can cost between £50 and £150, depending on the brand and specifications.

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. Repair costs can vary widely, ranging from £100 for a sensor replacement to £500 for more extensive engine repairs.

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.
