Keeping an E60 M5 healthy is mostly about consistency: the right fluids, sensible driving habits and dealing with small issues before they become big ones. Use this checklist as a starting point and adapt it with your specialist.
Driving habits
- Warm up properly. Wait until the oil is fully up to temperature before using high rpm. The rev-limit indicator on the tachometer helps show when the engine is ready.
- Use the revs regularly once warm. The engine is designed for it.
- Cool down after hard driving with a few minutes of gentle driving.
Engine
- Change the engine oil more frequently than the longest factory intervals, using the specified grade.
- Discuss a preventative connecting-rod bearing replacement with your specialist.
- Monitor oil level regularly — high-revving engines can use some oil.
- Check throttle actuators and their gears if warning messages appear.
- Replace spark plugs and inspect ignition coils at sensible intervals.
Cooling
- Inspect hoses, the expansion tank and the radiator for leaks or age.
- Replace coolant according to the recommended schedule.
SMG III
- Have the clutch wear and system values checked during services.
- Keep the hydraulic fluid in good condition and listen for the pump running excessively.
- Make sure the battery is healthy — low voltage can upset the SMG system.
Chassis
- Brake fluid every two years; inspect discs and pads regularly.
- Check bushings, control arms and wheel alignment.
- Use quality tyres in the correct sizes front and rear.
Electrics
A strong, correctly registered battery is essential on this car. Many seemingly random electronic faults trace back to low voltage.
