Standard annual servicing keeps your car running, but eventually, deeper maintenance is required to prevent cumulative wear. Over two years, brake fluid absorbs moisture, spark plugs wear down, air filters become blocked, and hidden mechanical issues can begin to develop.
Ignoring these longer-interval items often leads to expensive breakdowns or MOT failures. The "Old Way" involves losing your car for a day or two at a garage while they perform this extensive work. Maxamy Mobile Autocare offers the "Smart Way."
We bring the workshop to you. We perform this comprehensive 24-month service on your driveway or in your office car park.
We use OEM-quality parts and manufacturer-aligned procedures to reset your vehicle's baseline condition, ensuring it remains safe, efficient, and reliable for the road ahead.

A Major Service is recommended every 24 months or 24,000 miles. It serves as the most important milestone in your car's maintenance cycle. You should book this service if:
Service Interval Due: It has been two years since your last major service, and your vehicle requires a deep reset.
Mileage Milestone: You have covered approximately 24,000 miles since the last deep check, meaning longer-life components are now past their best.
Used Car Reset: You have just purchased a used vehicle with a mixed or unclear service history and want to establish a clean slate for peace of mind.
Performance Issues: The car feels sluggish, fuel economy has dropped, or the engine isn't running as smoothly as it used to.
Long-Term Ownership: You plan to keep the vehicle for several more years and want to minimise the risk of future repair bills.
This is not just a visual check. Maxamy Mobile Autocare performs a rigorous 71 point point inspection and a comprehensive schedule of part replacements to restore your vehicle's performance.
Ensuring engine longevity is crucial. We begin by draining the old oil and replacing the oil filter to eliminate contaminants. Then, we refill the system with the manufacturer-approved oil grade specific to your engine. This process guarantees optimal lubrication, minimises internal wear, and safeguards your manufacturer warranty.
Get an Instant PriceUnlike a standard service, a Major Service includes the replacement of additional filters and service items that degrade over longer periods. This typically includes the air filter (to improve engine breathing), the cabin/pollen filter (for air quality), and the fuel filter (for diesel engines) or spark plugs (for petrol engines) where applicable. This resets the engine's combustion efficiency and reliability.
Get an Instant PriceWe inspect the condition of all under-bonnet fluids. This includes testing the brake fluid for moisture content (which affects braking efficiency), checking the coolant antifreeze protection level (to prevent freezing or overheating), and inspecting power steering and transmission fluids where accessible.
Get an Instant PriceWe visually inspect wear-related components across the vehicle. This covers a detailed check of the braking system (pads, discs, lines), steering integrity, and suspension condition (springs, shock absorbers, bushes). We also assess tyre wear patterns, which can indicate alignment issues, and check all wheel bearings for play.
Get an Instant PriceWhere access allows, we inspect the underside of the vehicle for signs of corrosion, structural damage, or exhaust leaks. This helps identify issues that might cause an MOT failure or safety risk down the line. We also check drive shafts, gaiters, and mounting points for deterioration.
Get an Instant PriceAfter the physical work is complete, we perform a road test to validate the vehicle's handling, braking, and engine performance. We reset the service interval indicator on your dashboard and provide you with a clear report detailing the work done and any advisories found.

A major service is the most comprehensive level of routine maintenance and includes everything in a full service plus additional inspections and replacements that aren’t covered as frequently. It is designed to be carried out less often (typically every 24 months or around 24,000 miles) and gives a thorough check of the vehicle’s key systems. However, a major service should still sit within a structured programme of regular maintenance, including interim or full services in between, to ensure your car stays consistently well-maintained and safe.
Yes, we can service cars under manufacturer warranty by following the manufacturer's guidelines. Our major service uses only approved parts and fluids, ensuring that your warranty remains valid while maintaining your vehicle's performance and reliability.
Yes, during our major service, we will reset the service light to accurately reflect your vehicle's maintenance schedule. This assists you in tracking when the next service is needed, ensuring your car remains in excellent shape.
Yes, we can conduct a major service at your workplace or on a residential street, as long as the location is accessible. This service is designed for your convenience, allowing you to keep your vehicle in top condition without disrupting your daily routine.
On average, a major service takes between 90 minutes to two hours. This can change depending on the specific needs of your vehicle and the complexity involved. If further repairs or parts are needed, it could take a little longer.
Yes. A major service goes beyond what you can perceive when driving and includes detailed inspections and replacements of parts that aren’t checked every year. Cars often develop issues that aren’t obvious during normal use, and a major service helps catch these before they worsen. Even if your car feels fine, this level of servicing supports reliability and long-term performance, particularly as the vehicle ages or reaches higher mileage.
While a major service doesn’t replace the legal requirement for an MOT, it can help reduce the risk of failure. A major service involves very thorough checks and maintenance of systems that aren’t all covered by an MOT test, such as engine components, fluid quality, spark plugs and brake fluid. Addressing these areas in advance can minimise the likelihood of something causing the car to fail its MOT. It is good practice to schedule servicing and your MOT close together when possible.
Generally, yes. A major service is an investment in preventive maintenance. By identifying wear or early-stage faults before they develop into significant failures, it can reduce the likelihood of expensive repairs later on. Catching an emerging issue during a scheduled service is usually much cheaper than waiting until it causes a breakdown or more serious damage.
