Fuel Type:
Unleaded Premium Petrol (Octane rating typically 95 RON or higher)
Block Material:
Cast Iron
Cylinder Head Material:
Aluminum Alloy
Timing Mechanism:
Timing Belt (Driven by camshaft and crankshaft, requires periodic replacement)
Oil Change Interval:
Typically every 15,000 km (9,300 miles) or 12 months, whichever comes first. Refer to manual for specific model year and engine.
Timing Belt Replacement:
Recommended replacement interval for the 1.8T engine's timing belt is typically around 90,000-120,000 km (56,000-75,000 miles) or 5-7 years. Crucial for preventing catastrophic engine damage.
Spark Plug Replacement:
Refer to manual for specific intervals, typically around 60,000 km (37,000 miles) for standard plugs or longer for iridium/platinum plugs.
Engine Oil Specification:
API SJ/SL or ACEA A3/B3/B4. Viscosity grades typically 5W-40 or 0W-40, depending on climate. Consult manual for exact specification (e.g., VW 502 00).
Coolant Specification:
G12 or G12+ (pink colored) ethylene glycol-based coolant. Refer to manual for exact type and mixture ratio with distilled water.
Brake Fluid Specification:
DOT 4 brake fluid.
Transmission Fluid Manual:
Refer to manual for specific GL rating (e.g., GL-4 or GL-5) and viscosity for manual transmission. G 005 217 M2 is a common Audi spec.
Transmission Fluid Automatic:
Refer to manual for specific ATF specification (e.g., G 052 162 A1 for Tiptronic).
Ignition Coils:
Weak or failing ignition coils can lead to misfires, rough idling, and poor performance. Replacement is a common repair.
Pcv System:
The Positive Crankcase Ventilation (PCV) system can become clogged, leading to vacuum leaks, oil leaks, and rough running.
Oil Leaks:
Common oil leak points include valve cover gaskets, oil pan gaskets, and turbocharger oil lines.
Thermostat Housing:
The plastic thermostat housing is prone to cracking and leaking coolant.
Suspected Carbon Buildup:
Direct injection engines (though this model is port injected, it's a common issue in modern VW/Audi products) can suffer from carbon buildup on intake valves. While less of a concern for port injected 1.8T, it's worth noting for general Audi knowledge.
