Petrol
Check the rear ride height and look at the car from directly behind to inspect the rear wheel alignment. | Note: The Peugeot 106 rear trailing arm bearings wear out, leading to 'cambered' rear wheels (slanted inwards at the top) and a knock over bumps. A complete rear axle rebuild is often required if neglected.
Turn on the heater to maximum heat and fan speed, checking for a sweet smell in the cabin and inspecting the front footwell carpets for dampness. | Note: The heater matrix is prone to leaking on these models. Replacing it is extremely labor-intensive as it requires removing the entire dashboard.
During a cold start and warm-up, observe the idle stability and check for stalling when dipping the clutch at junctions. | Note: The TU5JP engine often suffers from a faulty idle control valve (stepper motor) or map sensor, causing hunting idle or sudden stalling.
Inspect the front-left corner of the engine block (near the alternator) for active oil leaks. | Note: The TU-series engines are notorious for head gasket oil leaks at this specific oil gallery corner. While it may pass a WoF initially, it will eventually contaminate the alternator and require a head gasket replacement.
Perform a standard lube service including engine oil and filter change. Inspect front brake pads and discs for wear. Lubricate door hinges and check tyre wear patterns.
Replace spark plugs, air filter, and fuel filter. Flush the brake fluid and coolant. Inspect the front suspension bush wear, especially control arm rear bushes, and check the condition of the auxiliary drive belt.
Critical timing belt (cambelt) and water pump replacement interval. Replace the gearbox oil (75W-80). Inspect the rear torsion bar axle for play and grease the trailing arm bearings if grease nipples have been retrofitted.
Verify the timing belt (cambelt) age and mileage; it must be changed every 4 years or 80,000km (whichever comes first) to prevent catastrophic engine damage.
Regularly flush the cooling system using high-quality coolant to prevent internal corrosion of the aluminum cylinder head and heater matrix.
Check and adjust valve clearances manually (inlet 0.20mm, exhaust 0.40mm cold) as the TU5JP 8-valve engine uses solid lifters that get noisy over time.
Inspect the fuel lines underneath the vehicle near the fuel tank for dry rotting and cracking, which is a common WoF fail point on older NZ-delivered 106s.
Clean the throttle body and idle air control valve periodically to maintain a smooth idle and prevent carbon buildup.
Estimated repair costs if issues arise
Required if trailing arm bearings have collapsed, causing knocking and uneven tyre wear. Sourcing refurbished axles in NZ can be difficult, often requiring import or specialist rebuilding.
Standard fix for the notorious TU-engine oil leak. Includes skimming the cylinder head, new head bolts, gasket kit, and coolant flush.
Essential preventative maintenance. Should always be done together with a fresh coolant fill to prevent premature failure of the new pump.
