1.6L I4 (TU5JP4)
Petrol
Drive the car until fully warm, then perform multiple starts, stops, and manual shifts if it is an automatic model. | Note: The AL4 4-speed automatic transmission is highly prone to pressure solenoid failure, leading to harsh shifts, 'Gearbox Fault' screen warnings, and the unit locking itself into 3rd gear (limp mode).
Cycle the indicators, high beams, and wipers repeatedly while turning the steering wheel lock-to-lock. | Note: The integrated steering column switch unit (COM2000) is notoriously unreliable. Failures cause self-cancelling indicators to fail, headlights to switch on randomly, or airbag warning lights to illuminate.
Drive over speed bumps and uneven chip-seal surfaces at 40-50 km/h, listening for knocking or rattling from the front end. | Note: Front suspension drop links, lower control arm bushes, and top strut mounts wear out prematurely on New Zealand roads, causing prominent clunking noises.
Park on a clean surface after the test drive, turn off the engine, and inspect the ground and engine bay with a torch. | Note: The TU5JP4 engine is prone to oil leaks from the rocker cover gaskets and coolant leaks from the plastic thermostat housing at the end of the cylinder head.
Standard minor service. Change engine oil (strictly use 5W-40 to PSA specification) and filter. Inspect cabin pollen filter, which often clogs and causes weak air-conditioning performance.
Intermediate service. Replace spark plugs, air filter, and fuel filter. Inspect front brake pads and discs for wear, and inspect the auxiliary drive belt for signs of cracking.
Critical major milestone. The timing belt and water pump must be replaced (strictly every 100,000 km or 4 years in NZ conditions). Inspect the engine mounts and suspension bushings for deterioration.
Replace the timing belt and water pump kit strictly every 100,000 km or 4 years to prevent catastrophic valve-to-piston damage.
Monitor the plastic thermostat housing regularly for hairline cracks and coolant seepage.
Maintain a healthy battery; low voltage easily triggers false warning lights and erratic behavior in the sensitive multiplex (BSI) electrical system.
Use only Peugeot-approved coolant (PSA B71 5110) to prevent internal corrosion of the heater matrix, which is expensive to replace.
Clean the throttle body periodically to cure rough idling and hesitation issues common to the 1.6L TU5JP4 engine.
Estimated repair costs if issues arise
Mandatory preventative maintenance. If the belt snaps, the engine is effectively write-off material.
Required if indicators fail to self-cancel or lights turn on automatically. Requires steering wheel removal and coding.
Necessary if the gearbox suffers from harsh shifting or throws pressure-related fault codes.
