Engine Options:
Likely covers 2.8L V6 (ACK, APR, AQD, ALG, AMX, ARE, AMN), 4.2L V8 (ASG, AQG), 2.7L V6 Bi-turbo (APU, ARE, BES), 1.8T 20V Turbo (AWT, AVV, ARK), and potentially 2.5L V6 TDI (BDG, BFC).
Horsepower Torque:
Detailed specifications for each engine variant, including horsepower and torque figures, power delivery curves, and engine speed ranges.
Fuel Delivery Type:
Primarily Multi-Point Fuel Injection (MPI) for naturally aspirated engines and FSI (Fuel Stratified Injection) where applicable, with turbocharger systems for 1.8T and 2.7T variants.
Valve Train:
DOHC (Double Overhead Camshafts) with 5 valves per cylinder for most gasoline engines. TDI variants likely utilize DOHC. Specifics on timing belt/chain replacement intervals and procedures.
Infotainment System:
The manual would cover the operation and troubleshooting of the Audi Navigation system (RNS-D), Chorus, Concert, or Symphony radio units, and their associated speaker systems.

Connectivity Options:
Information on features like voice control (if equipped), telephone preparation, and the Audi Music Interface (if applicable through aftermarket integration, though less common for this era).
Oil Change Interval:
Typically every 10,000 miles or 12 months, utilizing Audi's LongLife oil service system. Specifics for different oils and driving conditions will be detailed.
Timing Belt Replacement:
Crucial for 30-valve V6 and 1.8T engines, typically around 60,000 to 90,000 miles. TDI models utilize timing chains which have different service life considerations.
Engine Oil Type:
API SJ, ACEA A3/B3 or higher. Specific viscosity grades like 0W-40 or 5W-40 are common, depending on climate and manufacturer recommendations (e.g., VW 502 00 / 505 00).
