Vehicle Specs & Maintenance Data
The 2019 Audi A4 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 A4.
For oil changes, the 2019 Audi A4 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 A4, 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.
Owners of the 2019 Audi A4 have reported 5 common issues including "EA888 Engine Oil Consumption and PCV Valve Failure", "7-Speed S-Tronic (DL382) Shudder and Hesitation" and "LED Headlight Module Failure".

EA888 Engine Oil Consumption and PCV Valve Failure
The 2022 A4's 2.0L EA888 Gen 3B turbocharged engine continues the platform's history of oil consumption issues. The positive crankcase ventilation (PCV) valve, integrated into the valve cover, can fail and contribute to increased oil consumption, rough idle, and boost leaks. Owners report needing to add oil between the 10,000-mile oil change intervals.
Dealer replaces the valve cover assembly (which includes the integrated PCV valve) and performs an oil consumption test. Updated valve covers with improved PCV valve design are available. Use Audi-approved VW 508.00 specification oil. Reference Audi TSB 2044359/1 for oil consumption measurement procedures.
Est. Cost: $600 - $1,500 (valve cover); $3,000 - $4,500 (piston rings if needed)7-Speed S-Tronic (DL382) Shudder and Hesitation
The 7-speed S-Tronic dual-clutch transmission in the A4 exhibits shuddering during low-speed driving, hesitation from a standstill, and occasional rough shifts. The issue is most noticeable in stop-and-go traffic where the clutch packs are continuously slipping. Some owners describe a vibration through the drivetrain between 10-30 mph that resembles driving over rumble strips.
Dealer performs a transmission adaptation reset and TCU software update. The dual-clutch fluid should be changed using the specified G 052 529 A2 fluid. If the shudder persists, the clutch pack assembly may need replacement. Reference Audi TSB 2046783/2 for S-Tronic drivability issues.
Est. Cost: $300 (fluid change) - $4,000 (clutch replacement)LED Headlight Module Failure
The LED headlight modules on the 2022 A4 can develop partial failures where individual LED elements stop working, causing uneven light output or sections of the headlight beam going dark. The LED daytime running light signature may also lose individual segments, which is visually noticeable and can result in a failed state inspection in some jurisdictions.
Dealer replaces the LED headlight module inside the headlight assembly. In some cases, the entire headlight assembly must be replaced because the LED module is not separately serviceable. Audi has extended the headlight warranty on certain VIN ranges. Reference Audi TSB 2051724/1 for LED headlight diagnosis.
Est. Cost: $1,200 - $3,000 per headlightTurbocharger Wastegate Rattle
The turbocharger wastegate on the EA888 engine can develop a rattling or chattering noise at idle and low RPM. The wastegate actuator arm has slight play that allows the flapper valve to vibrate against the turbine housing. While the rattle does not typically affect performance, it is annoying and can worsen over time. The noise is most noticeable with the windows down near drive-throughs or parking garages.
Dealer adjusts the wastegate actuator arm tension or replaces the wastegate actuator. In some cases, the entire turbocharger assembly is replaced if the wastegate valve seat is worn. A software update to the boost control strategy can reduce wastegate flutter at idle. Reference Audi TSB 2039581/3 for turbocharger noise diagnosis.
Est. Cost: $200 (adjustment) - $2,500 (turbo replacement)Water Pump Thermostat Housing Coolant Leak
The integrated water pump and thermostat housing on the EA888 engine is a known weak point across the entire VAG platform. The plastic housing can crack, and the internal water pump impeller can degrade, causing coolant leaks and overheating. Owners notice coolant smell, visible leaks under the engine, and rising coolant temperature gauge readings.
Dealer replaces the water pump and thermostat housing assembly. Updated housings with reinforced plastic are available. The serpentine belt should be replaced at the same time since it must be removed for access. Coolant system should be flushed and refilled with Audi G13 coolant.
Est. Cost: $800 - $1,800
