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. Specialists recommend 7,500 miles for TFSI engines due to carbon buildup prevention. Use approved 5W-30 specification. Change filter every service. C7, 4K	10,000 miles or 1 year	£120–£180 Dealer: £200–£280
Air filter Replace every 20,000 miles. Inspect more frequently in dusty conditions. Critical for maintaining airflow to prevent turbo damage on TDI engines. C7, 4K	20,000 miles or 2 years	£40–£70 Dealer: £70–£100
Cabin pollen filter Annual replacement recommended. Clogged filter affects HVAC performance and can strain climate control system. Behind glove box access. C7, 4K	15,000 miles or 1 year	£60–£90 Dealer: £100–£140
Fuel filter 40,000 mile interval for TDI engines. Critical for preventing injector damage. Prime system after replacement. Include water separator drain. C7, 4K	40,000 miles or 4 years	£100–£160 Dealer: £160–£240

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 G 055 025 A2 specification fluid only. Prevents hesitant shifting issues. Includes filter replacement. C7, 4K	60,000 miles or 6 years	£350–£500 Dealer: £600–£850

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 2-year interval regardless of mileage. Critical for ABS and ESP system operation. Use DOT 4 specification only. Moisture absorption reduces boiling point. C7, 4K	2 years	£80–£120 Dealer: £120–£180
Coolant flush 5-year interval. Use G12++ specification coolant only. System holds 8-9 litres. Critical for preventing thermostat and water pump failures. Flush includes expansion tank and all hoses. C7, 4K	60,000 miles or 5 years	£150–£250 Dealer: £250–£350
Spark plugs 40,000 mile interval for TFSI engines. Use OEM specification plugs only - incorrect heat range causes misfires. Change at same time as ignition coils if over 80,000 miles. C7, 4K	40,000 miles or 4 years	£150–£250 Dealer: £250–£350
DPF forced regeneration service Preventive regeneration every 80,000 miles recommended by specialists. More frequent for city-driven cars. Manual regeneration prevents clogging. Monitor soot loading levels. C7, 4K	80,000 miles	£80–£150 Dealer: £150–£250
Auxiliary belt and tensioner Replace belt and tensioner together every 60,000 miles. Failed tensioner can cause alternator damage. Inspect for cracks and fraying every service. C7, 4K	60,000 miles or 6 years	£200–£300 Dealer: £350–£480
