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 10,000 miles or 12 months. XM/UM, UM	10,000 miles or 1 year	£80–£120 Dealer: £120–£180
Air filter Manufacturer interval 20,000 miles. Check at every service for contamination. Blocked filter reduces power and increases fuel consumption on turbo engines. XM/UM, UM	20,000 miles or 2 years	£25–£45 Dealer: £45–£70
Cabin pollen filter Manufacturer interval 20,000 miles. Replace more frequently in dusty or urban areas. Blocked filter reduces heater and air conditioning efficiency. XM/UM, UM	20,000 miles or 2 years	£20–£35 Dealer: £35–£55
Fuel filter Manufacturer interval 30,000 miles on diesel variants. Critical for fuel system protection. Blocked filter causes power loss and can damage high-pressure fuel pump. XM/UM, UM	30,000 miles or 3 years	£60–£90 Dealer: £90–£130

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
Automatic transmission fluid Manufacturer claims lifetime fill but specialists recommend 60,000-mile changes. Use only correct specification fluid. Neglected changes cause harsh shifting and transmission failure. XM/UM, UM	60,000 miles or 6 years	£200–£300 Dealer: £300–£450

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
Brake fluid Manufacturer interval 2 years regardless of mileage. Brake fluid absorbs moisture which reduces boiling point and causes internal corrosion of brake components. XM/UM, UM	2 years	£50–£80 Dealer: £80–£120
Coolant flush Manufacturer interval 60,000 miles or 5 years. Use only specified coolant type. Incorrect coolant causes corrosion and overheating issues. XM/UM, UM	60,000 miles or 5 years	£80–£120 Dealer: £120–£180
Auxiliary belt and tensioner Manufacturer interval varies. XM/UM, UM	60,000 miles or 6 years	£120–£180 Dealer: £180–£250
