Engine Variants Covered:
Likely covers 1.6L (ADP, AHL), 1.8L (ADR, APT, AVV), 1.8L Turbo (AEB, APU, ARK, AJL), 2.4L V6 (APG, BDV), 2.8L V6 (ACK, AHA, APR, AQD, ALG)
Horsepower Range:
Approximately 100 hp (1.6L) to 190 hp (2.8L V6, 1.8T)
Torque Range:
Approximately 140 Nm (1.6L) to 280 Nm (2.8L V6, 1.8T)
Injection Type:
Multi-point fuel injection (MPI) and/or direct injection (FSI for later models, but likely MPI for 1998 B5) managed by Electronic Engine Control (EEC)
Timing Belt Or Chain:
Varies by engine; many 4-cylinder engines use timing belts, V6 engines often use timing chains
Transmission Types:
5-speed Manual Transmission (e.g., GGB, FJW) and 4-speed Tiptronic Automatic Transmission (e.g., ECY, EWD, EWF)
Drivetrain:
Front-wheel drive (FWD) and quattro All-Wheel Drive (AWD)
Transmission Fluid Type:
Specific ATF for automatic transmissions (e.g., G052 162 A2) and gear oil for manual transmissions (e.g., G052 171 A2)
Oil Change Interval:
Typically every 15,000 km or 12 months, whichever comes first (or as per specific engine/oil recommendation)
Timing Belt Replacement:
Refer to manual; typically 60,000-90,000 km or 5-7 years for 4-cylinder engines, V6 engines often use chains with longer service lives.
Engine Oil Type:
API SJ or higher, ACEA A3/B3. Viscosity grades like 5W-40 or 5W-30 are common, depending on climate and specific engine. Consult manual for precise specs.
Coolant Type:
G12 (Purple) or G12+ coolant (ethylene glycol based) is recommended.
Common Problems B5:
PCV valve issues, oil leaks (valve cover gaskets, oil pan gasket), ABS sensor failures, coolant flange leaks, ignition coil failures (on 1.8T), window regulator failures.
Oil Filter Example:
Mann-Filter W 920/1, Mahle KL 145 (Verify specific part number for exact engine)
