1.6L (THP 155) - Petrol Turbo Automatic
Petrol
During your initial acceleration, gently listen for any hesitation or surging. In the 1.6L THP engine, carbon buildup on intake valves is something to keep in mind, so ensure the engine feels smooth under load.
Before setting off, cycle through the automatic transmission gears while stationary. Note if there are any harsh jolts or delays when shifting between Park, Reverse, and Drive, as these gearboxes benefit from timely fluid care.
While parked, observe the infotainment and cockpit controls carefully. The DS5 is packed with unique electronic features, so verifying that all switches and the retractable head-up display operate smoothly is a wise move.
Check the service history for consistent oil changes. These turbo engines are known to be sensitive to oil quality, so verify that the previous owner prioritized high-quality synthetic oil.
Consider a full transmission fluid refresh and inspection of the high-pressure fuel pump.
It is often a good time to evaluate the timing chain condition and check the turbocharger for any signs of excess play.
A comprehensive cooling system check, including the water pump and thermostat housing, is often recommended as standard maintenance at this stage.
Schedule regular oil and filter changes every 10,000km to keep the turbocharger happy.
Keep a close eye on your coolant levels and monitor for any signs of leaks around the plastic housing.
Regularly clean the cabin air filter to ensure the climate control system performs at its best.
Have the brake pads and rotors inspected during every warrant of fitness check.
Use premium 95 or 98 octane fuel to help maintain engine efficiency and cleanliness.
Estimated repair costs if issues arise
While not guaranteed to fail, some THP engines may eventually require attention to the timing chain tensioner. If this component needs attention in the future, it is a specialized job that ensures the engine remains timed correctly.
These pumps are vital for the direct injection system. Depending on the car's history, you might eventually need to budget for a replacement if the car begins to exhibit cold-start misfires.
Direct-injection engines can accumulate carbon deposits on the valves over time. A 'walnut blasting' or cleaning service can help restore lost performance and fuel economy if the car feels a bit sluggish.
