Precision Specifications:
Includes torque settings, fluid capacities, and clearances essential for correct assembly and performance.
Visual Guidance:
Features step-by-step diagrams to illustrate repair procedures and component locations.
Engine Variants Covered:
Likely covers 4-cylinder (e.g., 1.8L Turbo - AEB, APU, ARK) and V6 (e.g., 2.8L - ACK, AHA, APB) engines common in the B5 generation. Specific engine codes would be detailed within the manual.
Horsepower Range:
Typically 125 hp (2.6L V6), 150 hp (1.8T), 174 hp (2.8L V6), 190 hp (2.8L V6 Quattro).
Torque Range:
Specific torque figures for each engine variant will be detailed in the manual.
Injection System:
Bosch Motronic or similar multi-point fuel injection (MPI) systems.
Cylinder Arrangement:
Inline-4 and V6 configurations.
Aspiration:
Naturally aspirated and turbocharged (for 1.8T models).
Oil Change Interval:
Typically every 7,500 to 10,000 miles (or 1 year), depending on driving conditions and oil type. The manual will specify the exact interval and oil type.
Timing Belt Replacement:
For non-turbo 4-cylinder and V6 engines, timing belt replacement is typically recommended around 60,000-90,000 miles. The 1.8T may use a timing chain or belt, check manual for specifics.
Spark Plug Replacement:
Intervals vary by plug type (e.g., standard vs. platinum/iridium). Generally 30,000-100,000 miles.
Engine Oil:
Likely SAE 5W-40 or 0W-40 synthetic oil, meeting VW 502 00 specification. Manual will confirm.
Coolant:
G12 (pink) or G12+ (purple) ethylene glycol coolant, mixed 50/50 with distilled water.
Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, viscosity typically 75W-90.
Transmission Fluid Automatic:
G 052 162 A2 (or equivalent ATF) for Tiptronic transmissions. Check manual for exact specification.
Brake Fluid:
DOT 4 brake fluid.
Common Problems:
Examples include ignition coil failures (especially on 1.8T), mass airflow sensor (MAF) issues, coolant flange leaks, CV joint wear, window regulator failures, and oil cooler leaks. The manual addresses these and more.
Maintenance Focus:
Proactive maintenance as outlined in the manual is crucial for longevity, especially regarding timing belt (if applicable) and fluid changes.
