2.2L Hdi Torque:
Approx. 370 Nm (273 lb-ft)
Fuel System
Fuel System Diesel:
Common Rail Direct Injection (CRDi) with advanced injection pressures and electronic control.
Fuel System Petrol:
Multi-Point Injection (MPI) or Direct Injection (GDI) depending on specific engine variant.
Emission Control
Emission Control Diesel:
Diesel Particulate Filter (DPF) standard on HDi engines, Exhaust Gas Recirculation (EGR), Catalytic Converter.
Basic CD player with radio, optional navigation system (RT3/RT4), steering wheel audio controls. Connectivity may be limited compared to modern vehicles.
Driver Assistance
Driver Assistance Features:
Cruise control, parking sensors (rear, sometimes front), automatic headlights and wipers (on higher trims).
Connectivity
Connectivity Options:
Auxiliary input for audio (on some models), Bluetooth hands-free calling (optional).
🔧 Maintenance
Service Intervals
Oil Change Interval Diesel:
Typically 15,000 miles (25,000 km) or 2 years, whichever comes first. Consult manual for specific engine and oil type.
Timing Belt Interval Diesel:
Crucial for HDi engines. Typically 120,000 miles (200,000 km) or 10 years. Highly recommended to replace water pump and tensioners concurrently. Refer to manual for exact interval and engine code.
Fluid Specifications
Engine Oil Specification Diesel:
ACEA A5/B5 or C2 compliant, SAE 0W-30 or 5W-30 low SAPS oil. Refer to specific engine manual for exact viscosity and API/ACEA approvals (e.g., PSA B71 2290).
Coolant Specification:
PSA standard coolant (blue or pink ethylene glycol-based), mixed with de-ionized water at 50/50 ratio. Refer to manual for specific type (e.g., Type D).
Brake Fluid Specification:
DOT 4 brake fluid. Replace every 2 years regardless of mileage.
Known Issues
Common Hdi Issues:
DPF regeneration issues (especially with short trips), EGR valve clogging, turbocharger wear, injector problems, swirl flap actuator failure (on some engines).
Common Automatic Transmission Issues:
AL4 gearbox can be prone to hydraulic leaks, solenoid failures, and over-temperature issues if not maintained. Regular fluid changes are critical. GA6HP26Z generally more robust but still requires timely fluid service.
Common Electrical Issues:
