BMW 7-Series petrol servicing
BMW 7-Series petrol engines range from four-cylinder units (such as B48) to six-cylinder (such as N54, N55 and B58) and V8/V12 options (such as N63 and N74), so service requirements can differ significantly by model year and output. Keep on top of engine oil and filter changes, and include routine checks for coolant condition and any leaks, as high temperatures and packaging can make small issues escalate. On turbocharged petrol engines, listen for changes in boost response and address intake and vacuum leaks early, as they can affect drivability and emissions. Spark plugs and ignition components are also key service items on petrol models, with replacement needs varying by engine and use pattern.
