Major Repairs:
Engine rebuilding, transmission overhauls, suspension component replacement, and major electrical system repairs.
Component Replacement:
Step-by-step guides for replacing virtually all serviceable components from minor sensors to major drivetrain units.
Wiring Diagrams:
Complete, high-quality electrical schematics for all vehicle systems, enabling precise diagnosis and repair of electrical faults.
Depth Level:
Factory-level, comprehensive; suitable for professional technicians and advanced DIY enthusiasts.
Diagnostic Tools:
Implied use of factory diagnostic tools (e.g., VAS 5051/5052) for advanced diagnostics and programming.
Specifications Tolerances:
Detailed torque specifications, clearances, fluid capacities, and performance data for all major components and systems.
Oil Change Interval:
Typically every 10,000 miles or 12 months, depending on driving conditions (often referred to as 'flexible' service intervals by Audi). Manual will provide exact procedure and specifications.
Major Service Items:
Spark plug replacement (e.g., 60,000 miles), coolant flush, brake fluid flush, transmission fluid and filter (though Audi often claimed 'lifetime' fluid, periodic changes are recommended by many specialists).
Engine Oil Type:
Likely SAE 0W-40 or 5W-40, meeting VW 502 00 specification (e.g., Castrol Syntec or equivalent).
Coolant Type:
G12 Plus (or equivalent pink/purple coolant).
Common Problems:
Adaptive air suspension leaks (air struts/compressor), coolant leaks (valley pan gasket, coolant flanges), ignition coil failures, MMI system glitches, door lock actuators, and potential carbon build-up in FSI engines (though less pronounced than direct injection).
