In the complex world of vehicle maintenance, one clear piece of advice has emerged from seasoned mechanics; a simple, overlooked item can often cause a vehicle to fail its MOT. This item is none other than the humble windscreen washer fluid, which can cost as little as under £1 to refill. For such a minimal cost, regularly checking and refilling this essential fluid can prevent both inconvenience and potential MOT failure.

The MOT test, an annual requirement for vehicles over three years old in the UK, assesses a car’s safety, roadworthiness, and exhaust emissions. While many drivers focus on significant aspects such as brakes, tires, and lights, they often forget about smaller components, which can equally impact the test outcome. The windscreen washer system, though simple, contributes to clear visibility – a crucial element for safe driving. According to mechanics, a non-functional washer system is one of the most common, and frustratingly preventable, reasons vehicles fail their MOT.
Visibility problems account for a significant number of MOT failures. The windscreen washer fluid, responsible for keeping the windscreen clear of dirt, debris, and weather-related substances, is integral to maintaining optimum visibility. A car that arrives for an MOT with an empty windscreen washer reservoir fails to meet the required safety standards and will consequently fail the test. This simple oversight can be easily avoided with regular checks and top-ups, ensuring that the washer system is always in working order.

Experienced mechanics often cite that many drivers either forget or are unaware of the importance of windscreen washer fluid. As part of routine maintenance, it’s recommended to check fluid levels at least once a month and definitely before an MOT. This task takes just a few minutes: pop the hood, locate the washer fluid reservoir (typically a transparent container with a windscreen icon on the cap), and refill it using the appropriate washer fluid. This fluid is readily available at service stations and auto parts stores, often costing less than £1 per bottle.
Top-quality washer fluid includes detergents that help to remove bugs, road grime, and other residues without smearing, which water alone might not effectively handle. Some formulas also include anti-freeze, crucial for maintaining functionality during colder months. Using plain water, especially in winter, can result in freezing and potential damage to the system’s components, leading to more extensive repairs.
MOT testers also check for the functionality of the washer system. This includes ensuring that the washer jets are correctly aligned and capable of spraying a sufficient amount of fluid across the windscreen. Blocked or misaligned jets are another common issue that can lead to MOT failure. Drivers should ensure jets are clear by using a pin to dislodge any debris and verify the spray pattern reaches the entire windscreen. Adjustments can usually be done manually or with a screwdriver.
Besides the windscreen washer fluid, other small checks can prevent MOT failures. These include ensuring the car lights are operational, the tires are properly inflated and within legal tread limits, and that the windshield wipers are in good condition. While these items might seem insignificant, they all contribute to the overall safety and functionality of the vehicle.
Preventative maintenance is the key to passing an MOT. Regularly servicing the vehicle according to the manufacturer’s guidelines can help identify minor issues before they become major problems, thus ensuring that the car remains roadworthy year-round. Keeping a simple checklist of these minor checks, including the washer fluid level, can save time and money in the long run.
In summary, something as simple as an empty windscreen washer reservoir can see a vehicle failing its MOT, yet it takes just minutes and minimal expense to fix. By incorporating regular checks into their routine, drivers can ensure this minor but crucial component never causes them to face the inconvenience and cost of an MOT retest. So next time you’re preparing for your MOT, remember that a little washer fluid can go a long way in keeping your vehicle legally and safely on the road.
