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 was 6,000 miles or 12 months. MK2, MK3	6,000 miles or 1 year	£45–£65
Air filter Replace every 12,000 miles or when visibly contaminated. Blocked filter reduces power and increases fuel consumption. Check airbox for water ingress through damaged seals. MK2, MK3	12,000 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 Critical 40,000 mile interval on all engines. Replace water pump at same time as belt drives it. Interference engines - belt failure destroys valves and pistons. No warning before failure. MK2, MK3	40,000 miles or 4 years	£180–£280

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 12,000 mile manufacturer interval. Use correct heat range - incorrect plugs cause misfiring and poor fuel economy. Check plug condition for signs of oil burning or running lean. MK2, MK3	12,000 miles or 2 years	£25–£45
Brake fluid Mandatory 2-year replacement regardless of mileage. MK2, MK3	2 years	£35–£55
