All about the Citroën C5 AircrossAll about the 1.6 THP (EP6 turbo, also MINI Cooper S) engine
The 1.6 THP (EP6 turbo, also MINI Cooper S) engine was fitted to the Citroën C5 Aircross (2018–now). In the EU that is 21.4 % of all new cars of this generation.
Versions: 1.6 181 hp, 1.6 150 hp.
The most expensive known risk is high oil consumption: it usually appears at 60,000–200,000 km and costs €150–3,500 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Rattle for a few seconds after a cold start, later also warm; loss of power, engine light, camshaft timing codes; a jumped or broken chain wrecks the valves
Fix: Replace the full kit (chain, tensioner, guides, sprocket bolt) with the latest-version parts as soon as it rattles; keep oil changes short and the level topped up
Signs: Rough idle, hesitation and misfires, loss of response, engine light; worse with short trips
Fix: Clean the intake valves (walnut blasting) with the manifold off; it builds up again over time
Signs: Oil level drops fast (up to about 1 L per 1,000-1,500 km), oil warning, blue smoke; low oil then damages the chain and turbo
Fix: Check the oil at every fuel stop and top up; fix leaks and the crankcase breather first; valve stem seals or piston rings if the engine itself burns oil
Signs: Surging or jerking while driving, long cranking or hard hot starts, limp mode, low fuel pressure codes
Fix: Check rail pressure with a diagnostic tool and replace the high-pressure pump (latest version)
Signs: Coolant level keeps dropping, sweet smell, traces under the engine, temperature warning or overheating, fan not starting
Fix: Pressure-test the system; replace the leaking water pump or plastic thermostat housing with seals, and the temperature sensor if the fan does not switch on
Signs: Oil smell or burning oil on the exhaust side, oil traces at the turbo, whistling, loss of boost, underboost codes
Fix: Replace the oil feed pipe and its seals; if the turbo has shaft play or leaks oil, replace or recondition it together with new oil pipes
Signs: Freezes, climate controls on screen lag
Fix: Software update
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Signs: Jerks or clunks when slowing down or in town traffic, hesitation when pulling away, flare or slip when cold
Fix: Ask for the latest gearbox software and an adaptation reset; check the oil level and condition
Signs: Harsh or slipping shifts that get worse over time, dark burnt-smelling fluid, gearbox warning or limp mode
Fix: Change the fluid (several partial changes or a machine change with the correct Aisin / PSA fluid); if shifts stay bad, repair the valve body / solenoids or overhaul the gearbox
Typical routine maintenance cost for 100,000 km: €2,500–5,550. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
