    City & Guilds Level 1 Diploma in Vehicle Maintenance

    Topic Overview

    The City & Guilds Level 1 Diploma in Vehicle Maintenance introduces you to the fundamental skills and knowledge required to work in the motor vehicle industry. This qualification covers essential topics such as vehicle systems, workshop safety, and basic maintenance procedures. It is designed for those with little or no prior experience, providing a solid foundation for further study or entry-level employment in garages, dealerships, or fast-fit centres.

    Throughout the course, you will learn about the key components of a vehicle, including engines, brakes, steering, suspension, and electrical systems. Practical sessions focus on routine maintenance tasks like checking fluid levels, replacing bulbs, and inspecting tyres. Health and safety is a core theme, ensuring you understand how to work safely in a workshop environment, use tools correctly, and dispose of waste responsibly.

    This diploma is part of the wider Motor Vehicle & Transport suite, which progresses to Level 2 and Level 3 qualifications. It is ideal for school leavers or career changers looking to enter the automotive trade. By the end of the course, you will have the confidence to perform basic servicing tasks and understand how vehicles operate, preparing you for an apprenticeship or further technical study.

    Key Concepts

    Core ideas you must understand for this topic

    • →Vehicle systems: Understand the function and basic operation of the engine, transmission, braking, steering, suspension, and electrical systems.
    • →Workshop safety: Follow health and safety regulations, use personal protective equipment (PPE), and handle tools and equipment correctly to prevent accidents.
    • →Routine maintenance: Perform tasks such as checking and topping up fluids, inspecting belts and hoses, replacing wiper blades, and checking tyre pressure and tread depth.
    • →Tool identification and use: Know the names and purposes of common hand tools (spanners, sockets, screwdrivers) and workshop equipment (jacks, axle stands, ramps).
    • →Vehicle inspection: Carry out basic checks on lights, brakes, steering, and suspension to identify faults and ensure roadworthiness.

    Learning Objectives

    What you need to know and understand

    • Be able to work safely when carrying out removal and replacement activities, Be able to use relevant information to carry out the task, Be able to use appropriate tools and equipment, Be able to carry out removal and replacement of light vehicle chassis units and components., Be able to record information and make suitable recommendations

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating correct selection and use of personal protective equipment (PPE) and workshop equipment in line with safety protocols.
    • Award credit for accurately interpreting a vehicle service sheet or repair manual to identify removal and replacement procedures and torque specifications.
    • Award credit for safely supporting the vehicle using axle stands and removing the chassis component without damaging surrounding parts or systems.
    • Award credit for correctly refitting the component, applying specified torque settings, and performing a post-replacement functional check (e.g., brake operation, wheel alignment).

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always reference the vehicle workshop manual or service sheet before starting any physical work; this demonstrates process adherence and technical literacy.
    • 💡During practical assessments, narrate your actions to show the assessor your thought process, especially around safety checks and torque settings.
    • 💡Practice common chassis tasks, such as brake pad replacement and wheel bearing adjustment, until you can perform them methodically without omissions.
    • 💡Tip 1: In practical assessments, always demonstrate safe working practices first. For example, when jacking up a vehicle, chock the wheels, use axle stands, and never work under a car supported only by a jack. Examiners look for methodical, safe procedures.
    • 💡Tip 2: For written exams, learn the correct terminology. Instead of saying 'the thing that stops the car', use 'brake caliper' or 'brake pad'. Use diagrams to label parts accurately – practice drawing and labelling key components like the engine or braking system.
    • 💡Tip 3: When answering questions about maintenance intervals, refer to the vehicle's service schedule. For instance, oil changes are typically every 6,000-10,000 miles, but always check the manufacturer's recommendations. Be specific with numbers and units.

    Common Mistakes

    Common errors to avoid in your coursework

    • Attempting to remove a component without first consulting technical data, leading to improper procedure or damage to fasteners.
    • Failing to correctly support or secure the vehicle with axle stands, risking vehicle instability and personal injury.
    • Reusing single-use fasteners or neglecting to torque bolts to specification, potentially causing component failure after refitting.
    • Not performing a functional check after replacement, such as a brake test or steering inspection, missing a critical safety verification step.
    • Misconception: 'You don't need to wear PPE for simple tasks.' Correction: Always wear safety glasses, gloves, and steel-toe boots when working in the workshop, even for minor jobs like checking oil, as splashes or falling parts can cause injury.
    • Misconception: 'Tyre pressure is only important for fuel economy.' Correction: Incorrect tyre pressure affects handling, braking distance, and tyre wear, and can lead to blowouts. Always check pressure when tyres are cold and adjust to the manufacturer's specification.
    • Misconception: 'All warning lights on the dashboard are the same.' Correction: Different colours indicate severity: red means stop immediately (e.g., brake system), amber means caution (e.g., engine management), and green/blue indicate normal operation (e.g., headlights). Ignoring a red light can cause serious damage.
