Renault Austral MOT failure rates: what to expect
What fails on a Renault Austral at MOT, how often, and what each fix typically costs.

The Renault Austral often faces specific issues during its MOT tests. The most frequent failures include problems with the brakes, lights, and suspension components. Fixing these issues can vary in cost, but understanding them can help you prepare for your MOT and budget for necessary repairs.
Brake System Failures
One of the most common reasons the Renault Austral fails its MOT is due to brake system issues. This can include worn brake pads, discs, or even problems with the brake lines. A thorough inspection of the braking system is essential before the MOT.
Replacing brake pads typically costs around £100 to £150, while disc replacement can range from £150 to £300, depending on the quality of parts used. If there are issues with the brake lines, repairs can cost an additional £100 to £200. Regular maintenance of the braking system can help prevent these failures.
Lighting Issues
Lighting failures are another frequent cause of MOT failures for the Renault Austral. This includes problems with headlights, tail lights, and indicators not functioning properly. Given the importance of visibility and safety, ensuring all lights are operational is crucial.
Replacing a blown bulb usually costs between £10 and £30, while more complex issues, such as wiring faults, can lead to repair costs of £50 to £150. Regularly checking your lights can help avoid unexpected failures during the MOT.
Suspension Problems
Suspension components, including shock absorbers and springs, are vital for vehicle stability and comfort. The Renault Austral can experience wear and tear in these areas, leading to MOT failures. Symptoms of suspension issues include unusual noises or a bumpy ride.
Replacing shock absorbers can cost between £100 and £250 per pair, while spring replacement might range from £100 to £200. Addressing suspension problems promptly can enhance driving comfort and safety, as well as improve the chances of passing the MOT.
Tyre Condition
Tyres are a critical safety feature and are often scrutinised during the MOT. The Renault Austral may fail if the tyres are worn beyond the legal limit or if there are issues such as sidewall damage or uneven wear. Ensuring your tyres are in good condition is essential for both safety and compliance.
Replacing a single tyre can cost between £50 and £150, depending on the brand and size. Regularly checking tread depth and maintaining proper tyre pressure can help prevent premature wear and potential MOT failures.
Emissions and Exhaust System
Emissions testing is a key part of the MOT process, and the Renault Austral must meet specific environmental standards. Common issues include exhaust leaks or malfunctioning catalytic converters, which can lead to increased emissions and a failed test.
Repairing an exhaust leak can cost between £50 and £150, while a new catalytic converter can be significantly more expensive, ranging from £300 to £800. Keeping the exhaust system well-maintained can help ensure compliance with emissions standards.
Steering System Failures
The steering system is crucial for vehicle control and safety. Common failures in the Renault Austral can include issues with the steering rack or power steering system. Symptoms may include difficulty steering or unusual noises when turning.
Repairing or replacing a steering rack can cost between £200 and £500, depending on the extent of the damage. Regular checks on the steering system can help identify problems early and avoid costly repairs before the MOT.
