Audi Maintenance Plans

Use this Audi maintenance plan overview to understand what typically needs servicing and when, across the wide mix of engines and model families. Exact service items and intervals can vary by engine type, model year, and driving conditions, so always match the schedule to your specific Audi.

Select your Audi model below to access the maintenance schedule tailored to your vehicle.

Maintenance depending on the engine type

Audi gas engine maintenance

Audi gas engines commonly found across these ranges include families such as TFSI and FSi, along with 20V Turbo and V6 variants, and they can have different service requirements even within the same model line. Keep oil and filter changes on schedule, and use the correct oil specification, because turbocharged setups can be sensitive to neglected oil service. If your engine uses a timing belt, treat belt condition, tensioners, and the water pump as a single maintenance decision, since access overlaps and failures can be expensive. Also plan periodic replacement of spark plugs and air filters to help prevent misfires, rough running, and higher fuel use.

Audi diesel engine maintenance

Audi diesel engines place extra importance on using the correct oil specification and keeping up with filter service, especially the fuel filter, to protect high-pressure injection components. If your diesel is fitted with a DPF and EGR system, frequent short trips can increase soot loading and make drivability issues more likely, so consistent service is important. Glow plugs and their control circuits are also common wear items and can affect cold starting before a fault light appears. As with gas engines, confirm whether your specific diesel uses a timing belt and follow the correct interval for belt-related parts.

Routine Audi maintenance jobs

The operations table below highlights common Audi service tasks such as oil changes and timing belt checks or replacement. Use it as a starting point, then confirm the exact interval and specification for your engine because Audi service schedules differ across gas and diesel powertrains.

Job Interval Notes
Oil and filter changeDepending on engineVaries by engine and recommended oil grade
Air filter19,000 to 37,000 milesMore often in urban or dusty driving
Cabin filter9,000 to 19,000 miles or 1 yearAffects air conditioning and air quality
Brake fluid2 years (all models)Regardless of mileage
CoolantPer manufacturer (typically 5 years or 62,000 miles)Check level and condition (color, deposits) at every service
Front brake padsDepending on use (typically 19,000 to 37,000 miles)Wear depends on driving style and load carried
Timing belt15 000 kmInterval varies widely by engine
Spark plugs (gasoline)19,000 to 37,000 milesGasoline engines only

Audi electronic diagnostics

If an Audi develops a warning light or driveability issue, start by reading the stored OBD2 DTCs and freeze-frame data. You can look up code meanings and common causes here: Audi OBD2 fault codes. OBD2 codes are grouped by system (powertrain, chassis, body, and network), which helps you narrow the problem to areas like emissions controls, ignition/fueling, sensors, or communications. Codes guide diagnosis, but confirm with basic checks (fluids, vacuum leaks, wiring, and connectors) before replacing parts.

What the Audi technical manual covers

Knowing when to service your Audi is only half the job; the next step is doing the work correctly for your exact model and engine. A Haynes repair manual can walk you through workshop procedures step-by-step, including torque specs, tightening sequences, fluid capacities, and service-fit diagrams. That matters on jobs like timing belt service, where correct alignment and tensioning are critical. Choose the manual that matches your Audi range and engine so the instructions and specifications align with your vehicle.
