6 tracked service items across routine, major, and periodic schedules

Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service item	Interval	Typical cost
Engine oil and filter Manufacturer interval is 9,000 miles or 12 months. Critical on FIRE engines due to small oil capacity. Check level frequently between services as these engines can consume oil. 178	9,000 miles or 1 year	£45–£65
Air filter Manufacturer interval 18,000 miles or 2 years. Check more frequently in dusty conditions. Blocked filter reduces power noticeably on small engines. 178	18,000 miles or 2 years	£15–£25

Major service items

These are the big-ticket items. Miss them and you risk engine or gearbox damage. The costs are higher but the consequences of skipping are much worse.

Service item	Interval	Typical cost
Timing belt and tensioner Manufacturer interval 36,000 miles or 4 years. This is an interference engine - belt failure destroys valves and pistons. Replace water pump, auxiliary belt and tensioner at same time. 178	36,000 miles or 4 years	£280–£350

Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.

Service item	Interval	Typical cost
Spark plugs Manufacturer interval 18,000 miles or 2 years. Use NGK or Champion plugs to correct specification. Incorrect heat range causes poor running. 178	18,000 miles or 2 years	£35–£50
Brake fluid Manufacturer interval 2 years regardless of mileage. DOT 4 specification. Critical given the documented brake system issues on this model. 178	2 years	£40–£60
Coolant flush Manufacturer interval 36,000 miles or 4 years. Use correct Paraflu specification coolant. Do at same time as timing belt service. 178	36,000 miles or 4 years	£45–£65
