BMW M5 G90/G99 Maintenance Guide


Owning the G90/G99 M5 is as rewarding as it is demanding. Proper upkeep keeps the twin-turbo V8 singing and the chassis sharp. This guide covers service intervals, condition-based alerts, brakes and tyres, with nods to carbon-ceramic options. Whether you rack up motorway miles or tackle B-roads, these basics apply.


Maintenance Schedule

  • Running-in Service (RIS) - The first check arrives at 1,000 miles (1,600 km). Expect an oil and filter change, a general inspection of key components and a reset of the service interval.
  • Main Services - After running-in, plan a full service every 10,000–12,000 miles (16,000–19,000 km) or 12 months, whichever comes first. BMW’s condition-based system will flag items like oil, brake fluid and coolant inspections

Condition-Based Servicing

BMW uses sensors and driving data to decide when maintenance is required. Dash prompts appear in iDrive for oil level, brake lining wear and other checks. The owner’s manual lists each item, but the vehicle’s own alerts remove most of the guesswork.

We always recommend for our customers to use BMW-approved oils and filters to maintain correct tolerances and longevity for their vehicle. Typically, you will find that every year, and oil change and oil filter change is needed, on every second year add the Air Filter and Pollen Filter to this, and on every third year, add the Spark plugs too. If you use your vehicle hard, consider servicing the vehicle more frequently. 

Other Maintenance Points to Note

Brake Inspection - The M5’s kerb weight and performance place extra demands on its brakes. Check pad thickness and disc condition at every service—or sooner if you drive hard. Look for uneven wear or heat streaking on discs, and replace pads well before they hit minimum thickness.

Carbon Ceramic Brakes - Carbon-ceramic brakes are available as an upgrade on the G90/G99 M5. They cost significantly more and replacement discs can run into four figures per side. Benefits include far greater longevity and dramatically reduced dust. They resist fade under track conditions, but any replacement involves specialist labour and parts. Budget accordingly if you opt in.

Tyre Care - Tyres on the M5 wear quickly under heavy loads and spirited driving. Check pressures monthly, using the manual’s recommended psi. Rotate tyres every 5,000–6,000 miles (8,000–9,600 km) to even out wear. Replace any tyre showing uneven tread or cuts.

Final Thoughts

Keeping a G90/G99 M5 in top condition is straightforward if you stick to the schedule and heed the alerts. Use genuine parts, monitor wear items closely and never delay recommended services. With proper care, the M5 will reward you with decades of performance and reliability.
