Oil Change Interval:
Typically every 15,000 km or 12 months, but can vary based on driving conditions. Specific recommendations in the manual.
Timing Belt Interval:
For V6 and V8 engines using timing belts (check specific engines), typically around 90,000-120,000 km or 5-7 years. The 2000 models predominantly used timing chains, but belt-driven engines were also present. Manual provides definitive guidance.
Engine Oil Type:
API SJ or higher, ACEA A3/B3 or A3/B4, Viscosity: SAE 0W-30, 5W-40, or 5W-30 depending on ambient temperature. Specific Audi homologations (e.g., VW 502 00 / 505 00) are critical and detailed in the manual.
Coolant Type:
G12 or G12+ ethylene glycol based coolant, mixed 50/50 with distilled water. Refer to manual for exact Audi specification number (e.g., TL 774 F).
Brake Fluid Type:
DOT 4 or DOT 5.1. Manual will specify exact requirement and replacement interval.
Common Problems:
Coil pack failure, ignition module failure, camshaft position sensor issues, coolant flange leaks, automatic transmission valve body issues (especially on higher mileage units), ABS sensor failure, sagging headliner, power steering leaks, suspension component wear (e.g., control arm bushings).
Differential Issues:
Transfer case failures on quattro models, differential fluid changes recommended as per manual's schedule.
