BMW M4 G82/G83 Maintenance Guide

BMW M3/M4 G80/G82 S58 Maintenance Guide

The M3/M4 G80/G82's are equipped with the S58 engine and they represent the latest evolution in BMW’s M series, combining high performance with cutting-edge technology. For prospective buyers or existing owners, understanding the maintenance requirements of these Bavarian Brutes is essential for keeping the car in peak condition. This guide outlines the key maintenance considerations, service schedules, and important part requirements, tailored for the UK market.

BMW M3/M4 G80/G82 Service Schedule

As with any high-performance vehicle, regular servicing is essential to ensure your car runs smoothly and reliably. BMW recommends adhering to a structured service schedule to maintain the performance of the S58 engine and other critical components.

Running-in Service

One key aspect of owning a new BMW M3/M4 G80/G82 is the running-in service, which should be performed after the first 1,200 miles (or 2,000 km). This is a crucial service, as it ensures that the engine and other mechanical components are properly broken in, which helps avoid premature wear. During the running-in period, it’s important to drive conservatively, avoiding high engine speeds and heavy loads. The running-in service typically includes:

• Oil and filter change: Fresh oil helps to flush out any contaminants from the initial engine use.
• Inspection of mechanical components: Ensuring everything is in proper working order after the initial break-in period.

This service is essential for maintaining your vehicle's longevity, and it is best carried out at an authorised BMW service centre.

Regular Service Intervals

BMW typically recommends service intervals every 10,000 miles (or 16,000 km) for the M3/M4 G80/G82, though this can vary depending on driving conditions. These services generally include:

1. Oil and filter change: Crucial for keeping the S58 engine running smoothly.
2. Inspection of engine components: Checking the health of the turbochargers, timing chains, and other key engine parts.
3. Brake fluid change: This should be done every two years to maintain proper braking performance.
4. Inspection of suspension and alignment: To ensure the car’s handling is at its best.
5. Inspection of cooling system: Checking for any signs of coolant leaks or degradation.

Major Service Intervals

Every 40,000 miles (or 64,000 km), the M3/M4 G80/G82 should undergo a more thorough service, which includes:

• Air filter replacement: Important for ensuring the engine breathes efficiently.
• Spark plug replacement: Necessary for maintaining proper ignition and combustion.
• Fuel filter replacement: Ensuring fuel flow is clean and unobstructed.
• Transmission and differential fluid change: To maintain smooth shifting and overall drivetrain health.

Consider servicing your car prior to BMW's schedule if you use the car particularly hard, or track the vehicle. 

Pre-LCI vs. LCI Models: Maintenance Considerations

The Pre-LCI (Life Cycle Impulse) and LCI (facelifted) versions of the M3/M4 G80/G82, while both equipped with the S58 engine, may have small differences in terms of parts and systems. For example, LCI models may feature minor updates to electronics or additional features that could impact the service process. However, the core maintenance schedule and part requirements remain the same between both versions.

It’s important to check the exact specification of the model you're purchasing, as any additional technology or parts updates might influence service procedures or component replacement intervals. Always ensure that any updates are handled by an authorised BMW dealer or specialist.

Critical Components and Part Requirements

The M3/M4 G80/G82 S58 engine is a robust unit, but like any performance engine, it requires the correct parts and fluids to maintain optimal performance.

Engine Oil

Using the correct grade of engine oil is vital for the S58 engine. BMW recommends using high-quality synthetic oil that meets BMW’s Longlife-01 FE standard. Oil changes should be carried out as per the recommended service schedule to avoid excessive engine wear.

Brake Pads and Discs

As performance-oriented vehicles, the M3/M4 G80/G82 will likely undergo heavy braking, particularly if used on track or for spirited driving. It is essential to monitor the condition of the brake pads and discs regularly. BMW recommends replacing brake pads every 30,000-40,000 miles (48,000-64,000 km), depending on usage, and inspecting the brake fluid every two years.

Suspension Components

The suspension system of the M3/M4 G80/G82 should be regularly inspected, especially if the car is used on the track or for aggressive driving. Parts such as bushings, control arms, and dampers may wear more quickly under high-performance use. Checking for any play or unusual noises in the suspension is important to avoid any long-term damage.

Tyres

Given the high-performance nature of these cars, tyres should be checked regularly for tread wear, particularly on the inner edges, which may wear more quickly with aggressive cornering. Replace tyres when the tread depth drops below the legal minimum of 1.6mm, but consider replacing them sooner if they show signs of uneven wear, especially after track use.

Cooling System

Maintaining the cooling system is essential for preventing overheating during performance driving. Regularly inspect coolant levels and hoses for signs of leaks or degradation, especially if the car is used on track. The S58 engine can generate a lot of heat under load, so ensuring the radiator, intercooler, and oil cooler are in optimal condition is critical.

If you track the vehicle or drive particularly hard, consider looking into aftermarket cooling upgrades to keep that S58 engine happy!

Transmission and Differential Fluids

While the M3/M4 transmission and differential are generally robust, it’s important to change the transmission and differential fluids at the recommended intervals (typically every 40,000 miles or 64,000 km). This helps ensure smooth shifting and longevity of the drivetrain components, particularly if the car is used aggressively on the track.

Other Considerations

• Warranty: These cars are covered by a standard BMW warranty, but as with any high-performance vehicle, it’s crucial to ensure that any modifications or heavy usage do not void the warranty. If the car has been modified, check that the modifications are professionally installed and documented.
• Track Use: If the car has been used for track days, it’s important to ensure that the key components such as the brakes, suspension, and tyres have been regularly checked or replaced. Track driving can cause accelerated wear, so be vigilant in monitoring the condition of these components.

Conclusion

The BMW M3/M4 G80/G82 with the S58 engine are high-performance vehicles that requires regular and meticulous maintenance to ensure it continues to deliver exceptional driving experiences. Following the recommended service schedule and using the correct parts will keep the car in top condition and help avoid any major issues. Whether you own a Pre-LCI or LCI model, adhering to BMW’s maintenance guidelines will ensure that your M-Car continues to perform at its best for years to come.
