Covers fuel injection systems, fuel pump specifications, pressure testing, and component servicing.
Cooling System Components:
Radiator, water pump, thermostat, coolant specifications, and bleeding procedures.
Oil Specifications:
Engine oil types, viscosity grades (e.g., VW 500 00, VW 501 01, VW 502 00 for petrol engines), and capacities.
Manual Transmission Types:
Details for the manual transmissions offered, likely including 5-speed gearboxes (e.g., DQZ, EFA).
Automatic Transmission Types:
Details for automatic transmissions, likely the 4-speed automatic (e.g., AFF, AZJ) or potentially the early DSG precursors if applicable to the 1998 model year, though less common.
Clutch Service:
Clutch replacement procedures, hydraulic system servicing, and adjustment.
Crash Test Data:
While specific crash test ratings for the 1998 model might not be in the manual itself, the manual covers Supplemental Restraint Systems (SRS) and seat belts, which are critical safety components.

Details on the factory-fitted engine immobilizer system and its electronic components.
Oil Change Interval:
Typically every 15,000 km (approx. 9,300 miles) or 12 months, whichever comes first, subject to driving conditions and oil specification used (flexible service intervals might have been introduced).
Other Maintenance Intervals:
Spark plug replacement, air filter replacement, fuel filter replacement, timing belt replacement (if applicable to specific engine variants), brake fluid flush, coolant flush.
Coolant Type:
G12 coolant (or equivalent specification, e.g., VW TL 774-C) and its mix ratio with distilled water.
Brake Fluid Type:
DOT 4 brake fluid.
Power Steering Fluid:
Specific hydraulic fluid, often VW TL 521 46 or similar.
Common Wear Items:
Front suspension components (control arms, ball joints, bushings), ignition coils (especially on 1.8T models), window regulator mechanisms, catalytic converters, rear shock absorbers.
Engine Specific Notes:
Potential for oil leaks from valve cover gaskets and oil pan seals. Timing belt maintenance is critical on naturally aspirated engines.
