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 specifies 10,000 miles or 12 months. 8T	10,000 miles or 1 year	£120–£180 Dealer: £200–£300
Air filter Standard interval is 20,000 miles. Check more frequently in dusty conditions. Dirty filter reduces performance on forced induction engines. Replace cabin pollen filter at same time. 8T	20,000 miles or 2 years	£40–£80 Dealer: £80–£150

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 chain tensioner inspection Not specified by manufacturer but critical on supercharged 3.0 TFSI. 8T · CGWC	60,000 miles or 6 years	£800–£1200 Dealer: £1500–£2200
DSG transmission fluid and filter Manufacturer interval is 40,000 miles. 8T	40,000 miles or 4 years	£300–£400 Dealer: £450–£650

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 specifies 40,000 miles. 8T	40,000 miles or 4 years	£150–£250 Dealer: £250–£400
Brake fluid Every 2 years regardless of mileage. Use DOT 4 brake fluid meeting VW 501.14 specification. Performance models generate high brake temperatures requiring fresh fluid for consistent pedal feel. 8T	2 years	£80–£120 Dealer: £150–£250
Coolant system flush Long-life coolant specified for 6 years initially, then 4-year intervals. 8T	80,000 miles or 8 years	£150–£250 Dealer: £300–£450
