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 12,500 miles or 12 months. Mk1, Mk2, Mk3	12,500 miles or 1 year	£80–£120 Dealer: £140–£200
Air filter Replace every 25,000 miles or 2 years. Dirty filter reduces performance and increases fuel consumption. Mk1, Mk2, Mk3	25,000 miles or 2 years	£20–£40 Dealer: £40–£70
Cabin pollen filter Replace every 25,000 miles or 2 years. Blocked filter causes poor cabin ventilation and window misting. Mk1, Mk2, Mk3	25,000 miles or 2 years	£25–£45 Dealer: £45–£75
Fuel filter Diesel models only. Replace every 37,500 miles or 4 years. Blocked filter causes loss of power and poor starting. Mk1, Mk2, Mk3 · DV4, DV6, DV5	37,500 miles or 4 years	£60–£100 Dealer: £100–£160

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 (wet system) PureTech engines use timing belt running in engine oil. Mk2, Mk3 · EB2	100,000 miles or 10 years	£800–£1200 Dealer: £1500–£2500

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 varies by engine. Use correct heat range spark plugs. Misfiring can damage catalytic converter. Mk1, Mk2, Mk3	37,500 miles or 4 years	£80–£120 Dealer: £120–£180
Brake fluid Replace every 2 years regardless of mileage. Use DOT 4 specification fluid. Hygroscopic fluid absorbs moisture and reduces braking efficiency. Mk1, Mk2, Mk3	2 years	£60–£90 Dealer: £90–£140
Coolant flush Manufacturer interval 150,000 miles or 10 years. Use correct antifreeze specification for aluminium engines. System flush prevents corrosion and blockages. Mk1, Mk2, Mk3	150,000 miles or 10 years	£80–£120 Dealer: £120–£180
DPF forced regeneration DPF regenerates automatically during motorway driving. Cars used for short journeys require periodic forced regeneration to prevent DPF blockage. Warning light indicates regeneration needed. Mk1, Mk2, Mk3 · DV4, DV6, DV5	500 miles	£80–£120 Dealer: £120–£200
