Vehicle Specs & Maintenance Data
The 2017 Audi S3 maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Audi S3.
For oil changes, the 2017 Audi S3 takes 5W-40 Full Synthetic motor oil with a capacity of 5.7 quarts. Brake fluid type is DOT 4, the recommended coolant is G13 (Purple, phosphate-free), and transmission fluid is VW G 055 025 A2. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Audi S3, torque the lug nuts to 89 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2017 Audi S3 owners, with recommended fixes and estimated repair costs.
Water Pump and Thermostat Failure
The EA888 2.0T engine's water pump and thermostat housing are prone to failure, causing coolant leaks and potential overheating. The plastic thermostat housing can crack, and the water pump impeller can degrade. This is one of the most common EA888 issues.
Replace the water pump and thermostat housing assembly with updated revision parts. Audi released an improved design with a metal thermostat housing. Preventive replacement around 60,000-80,000 miles is recommended.
Est. Cost: $600 - $1,500DSG Mechatronic Unit Failure
The DQ250 6-speed DSG transmission mechatronic unit can develop electrical faults causing harsh shifting, failure to engage gears, or getting stuck in neutral. Warning lights for the transmission appear on the dashboard.
Replace the mechatronic unit or perform an internal repair of the solenoids and valve body. Software updates to the TCM may resolve minor shifting issues. The DSG fluid and filter should be serviced every 40,000 miles.
Est. Cost: $1,500 - $4,000Turbo Diverter Valve Failure
The factory diverter valve (DV) on the 2.0T engine tears or cracks, causing boost leaks that result in power loss, rough idle, and a fluttering sound under boost. The rubber diaphragm deteriorates over time.
Replace the diverter valve with an updated OEM revision or an aftermarket piston-style DV that eliminates the rubber diaphragm failure point. A simple bolt-on replacement that takes about 15 minutes.
Est. Cost: $100 - $400Carbon Buildup on Intake Valves
Direct injection engines like the EA888 are susceptible to carbon buildup on the intake valves since fuel does not wash over them. This causes rough idle, misfires, reduced power, and poor fuel economy, typically appearing after 40,000-60,000 miles.
Walnut blasting of the intake valves to remove carbon deposits. Some owners install an aftermarket oil catch can to reduce future buildup. Audi TSB addresses this with updated PCV valve design.
Est. Cost: $400 - $800High-Pressure Fuel Pump (HPFP) Failure
The high-pressure fuel pump cam follower can wear prematurely, leading to fuel pump failure, long crank times, limp mode, and potential engine damage if metal debris enters the fuel system. More common on earlier EA888 Gen 1/2 engines.
Replace the HPFP cam follower preventively at every oil change interval. If the pump has failed, replace the HPFP assembly. Inspect the camshaft lobe for scoring. Audi extended warranty coverage for some affected vehicles.
Est. Cost: $50 (cam follower) - $2,500 (complete HPFP and cam)
