2.2L I4 Turbo (DW12MTED4)
Diesel
Drive the vehicle at highway speeds (80-100 km/h) and check for any 'depollution system faulty' warnings on the dashboard or sudden power loss (limp mode). | Note: The 2.2L DW12 diesel engine relies on an Eolys additive system for DPF regeneration. If the additive tank runs dry or the DPF clogs due to frequent short urban trips, repairs can be extremely expensive.
Accelerate gently from a complete stop on an incline and feel for any shuddering, hesitation, or harsh clunks as the gears engage. | Note: For models fitted with the DCS6 Getrag dual-clutch transmission, neglected fluid changes lead to premature clutch wear, solenoid failure, or complete mechatronic unit breakdown.
Listen for a distinct metallic rattling or knocking noise at idle that disappears when the clutch pedal is depressed (on manual models) or under light load. | Note: The dual-mass flywheel (DMF) on high-torque diesel engines like the DW12 is a common wear item. A failing DMF will eventually slip or damage the gearbox bellhousing.
Perform a hard acceleration run from 2000 RPM in 3rd gear while listening for high-pitched whistling noises or checking the rearview mirror for black smoke. | Note: Split intercooler hoses and sticky variable geometry turbocharger (VGT) vanes are common on this powertrain, resulting in boost leaks and poor performance.
Perform a standard lube service including high-grade low-SAPS engine oil (critical for DPF health), oil filter replacement, and inspection of front/rear brake pads. Check Eolys fluid levels.
Conduct a major service. Replace the fuel filter (highly sensitive on this common-rail diesel) and cabin filter. Perform a complete fluid and filter exchange on the DCS6 dual-clutch transmission if fitted.
Replace the timing belt, tensioners, and water pump (due at 100,000 km or 7 years under severe operating conditions). Drain and refill the transfer case and rear differential fluids.
Verify timing belt and water pump replacement history, ensuring it has been done within the last 7 years or 100,000 km.
Check DCS6 dual-clutch transmission service history to ensure fluid was changed every 45,000 km to 60,000 km.
Scan the engine control unit (ECU) for stored DPF soot load levels and Eolys additive fluid status.
Inspect the turbocharger intercooler hoses and intake pipework for signs of cracking or oily weeping.
Ensure the 4WD selector dial operates correctly and engages 2WD, 4WD Auto, and 4WD Lock modes smoothly.
Estimated repair costs if issues arise
Preventative maintenance interval; failure will cause catastrophic engine damage. Must be done by a mechanic familiar with PSA diesel engines.
Requires specialized high-grade SST fluid and filter replacement every 45,000 km to prevent transmission failure.
Required if the particulate filter is heavily soot-loaded or if the Eolys additive system has been ignored for too long.
