2000 — 2001
1.6L I4 (TU5JP)
Petrol
Examine the rear wheels from a distance behind the car to check for negative camber (wheels leaning inward at the top) and listen for metallic knocking or creaking noises over bumps. | Note: The rear suspension trailing arm bearings fail frequently, causing the wheels to tilt, rub on the inner arches, and eventually require a complete rear axle rebuild or replacement to pass a NZ WoF.
Let the engine idle up to operating temperature. Check the engine block (specifically the front-left corner under the alternator) for oil leaks, and inspect the coolant expansion tank for oil residue. | Note: The TU5JP engine is notorious for head gasket failures, most commonly manifesting as an external oil leak, but internal coolant/oil mixing is also common if the car has overheated.
Operate every electrical control repeatedly, specifically testing if the indicators self-cancel correctly and if the headlights flicker or turn off when using the turn signals. | Note: Post-2001 multiplexed (MUX) models utilize a fragile column switch unit (COM2000) which is expensive to replace and prone to failing, causing erratic lighting and indicator behavior.
On automatic models (AL4 4-speed), drive until the car is fully warm. Watch for harsh downshifts, slipping, or the 'Sport' and 'Snow' dash lights flashing simultaneously. | Note: The AL4 automatic transmission is highly temperamental in NZ conditions. Flashing lights indicate the gearbox has entered limp mode, usually caused by faulty pressure modulation solenoids.
Routine engine oil and filter change using quality 10W-40 semi-synthetic oil. Inspect front brake pads and discs, cabin pollen filter, and check for any diagnostic trouble codes.
Critical timing belt and water pump replacement milestone (must be done every 60,000km or 4 years, whichever comes first). Replace spark plugs, air filter, and perform a full brake fluid flush.
Inspect rear axle play thoroughly, replace the manual gearbox oil or perform an AL4 automatic fluid flush, replace auxiliary drive belts, and inspect all cooling system hoses for brittleness.
Verify the timing belt age and mileage history; a snapped belt will instantly destroy the TU5 cylinder head valves.
Keep the battery voltage healthy; low battery voltage causes the Peugeot BSI (body control computer) to glitch and trigger phantom warning lights.
Monitor coolant levels weekly, as air locks or minor leaks can quickly lead to localized overheating and head gasket failure.
Lubricate the rear axle trailing arm pivot points if grease nipples have been retrofitted by a previous owner to extend bearing life.
Use only high-grade Peugeot-approved coolant (PSA G33 or equivalent) to prevent internal corrosion of the alloy engine components.
Estimated repair costs if issues arise
Necessary if trailing arm bearings have seized and damaged the axle tube. Common NZ WoF failure point.
Required to fix chronic external oil leaks or internal coolant mixing on the TU5JP 1.6L engine.
Parts cost is high for genuine PSA units; aftermarket units are available but require careful coding/matching.
