Maintenance
|
Service Intervals
|
Oil Change Interval Conventional:
|

|
Timing Belt Replacement V6:
|
Typically every 90,000 - 100,000 km (56,000 - 62,000 miles) for 2.8 V6 engines. Crucial to follow manual recommendation due to interference engine design.
|
Timing Belt Replacement 1 8T:
|
Approximately 100,000 km (60,000 miles) for 1.8T engines. Crucial to follow manual recommendation due to interference engine design.
|
Fluid Specifications
|
Engine Oil Type:
|
Refer to manual for specific API/ACEA ratings and viscosity grades (e.g., 5W-40, 0W-40). Often VW 500.00 or 502.00 specification.
|
Coolant Type:
|
G12 or equivalent propylene glycol-based coolant with corrosion inhibitors.
|
Transmission Fluid Manual:
|
API GL-4 or GL-5 gear oil, SAE 75W-90 or 75W-85 viscosity. Refer to manual for exact specification.
|
Transmission Fluid Automatic:
|
Audi-approved ATF fluid (e.g., G 052 162 A2 or equivalent). Non-compatible fluids can cause severe damage.
|
Brake Fluid:
|
DOT 4 specification.
|
Known Issues
|
Ignition Coil Failure 1 8T:
|
Early models (especially 1.8T) are prone to ignition coil failure, leading to misfires.
|
Mass Air Flow Sensor:
|
MAF sensor can become dirty or fail, affecting engine performance and fuel economy.
|
Crankshaft Position Sensor:
|
Failure of the crankshaft position sensor can lead to no-start conditions or stalling.
|
ABS Wheel Speed Sensors:
|
ABS warning lights often indicate failing wheel speed sensors.
|
Climate Control Actuators:
|
Blend door actuators in the HVAC system can fail, leading to improper temperature control.
|
Power Steering Pump Leaks:
|
Potential for leaks from the power steering pump or hoses.
|
Window Regulator Failure:
|
Power window regulators can fail over time.
