Engine Options 1:
1.6L I4 (ADP, AHL, ANA)
Engine Options 2:
1.8L I4 (ADR, APT, APU, ARK, AVC, AVV) - 20v, 5v variants
Engine Options 3:
1.8L Turbo I4 (AEB, AJL, APU, ANN, AWT)
Engine Options 4:
2.6L V6 (ABC, AAH)
Engine Options 5:
2.8L V6 (AAH, ACK, ALG, AMX, APR, AQD, ATQ, AUV)
Engine Options 6:
1.9L TDI I4 Diesel (AHH, AJM, AVG, AFF, AKU, BKE)
Hp Range:
101 hp (1.6) to 190 hp (2.8 V6)
Torque Range:
140 Nm (1.6) to 280 Nm (2.8 V6)
Injection Type:
Multi-Point Fuel Injection (MPI) / Direct Gasoline Injection (GDI for some 1.8T) / Common Rail Diesel Injection (CRDI for TDI)
Fuel Type:
Unleaded gasoline (91 RON minimum) / Diesel (for TDI models)
Oil Change Interval Gasoline:
Typically 15,000 km (9,300 miles) or 12 months, whichever comes first (may vary based on driving conditions and oil type).
Oil Change Interval Tdi:
Typically 10,000 km (6,200 miles) or 12 months, whichever comes first (diesel engines often have shorter intervals).
Timing Belt Replacement:
For 1.6L, 1.8L, and 2.6L/2.8L V6 engines: typically every 90,000 - 120,000 km (56,000 - 75,000 miles) or 5-7 years. TDI engines often use a timing chain or have different belt intervals.
Engine Oil:
API SG/SH or ACEA A2/A3, viscosity grades like 5W-40, 10W-40, or 15W-50 depending on climate and manufacturer recommendation.
Coolant:
G12 (pink) ethylene glycol-based coolant mixed with distilled water (50/50 ratio).
Brake Fluid:
DOT 4 or DOT 3 brake fluid.
Transmission Oil Manual:
API GL-4 or GL-5 gear oil, e.g., SAE 75W-90 or 75W-80.
Transmission Oil Automatic:
ATF Dexron III or equivalent.
Ignition Coils:
Failure of ignition coils, leading to misfires and rough running, particularly in 1.8T models.
Suspension Components:
Wear in control arm bushings, ball joints, and tie rod ends leading to steering looseness and uneven tire wear.
Window Regulators:
Plastic components in window regulator mechanisms can break, causing windows to fall into the door.
ABS Sensors:
ABS wheel speed sensors can fail, causing the ABS warning light to illuminate and loss of ABS function.
Climate Control Unit:
Malfunction of the climate control module, leading to erratic fan speeds or inoperative A/C/heating.
Oil Leaks:
Leaking valve cover gaskets, oil pan gaskets, and crankshaft seals are common with age and mileage.
