1992 Proton 1.5 GL 1.5L Petrol · K556 KYJ

The most recent MOT recorded on 6 October 2021 resulted in a failure, with four major exhaust emission defects, a non‑functioning nearside rear direction indicator and ineffective front windscreen wipers. With only a single MOT entry available, there is no clear long‑term trend, but the failure indicates that the vehicle has not been kept to the standards required for roadworthiness at that point in time and that remedial work is likely overdue. At 34 years old the Proton has logged just 50,956 miles, averaging roughly 1,500 miles per annum. Such a low annual usage suggests the car has spent considerable periods idle or on very light duty. While low mileage can be a positive sign for engine wear, prolonged standing accelerates the ageing of rubber components, seals and electrical connections, and can promote corrosion on the chassis, suspension joints and brake hardware. Any future buyer should be aware that the low mileage figure does not guarantee the condition of time‑sensitive parts. The exhaust emission failures point to a possible fault in the fuel‑air mixture control, a deteriorating catalytic converter, or a malfunctioning lambda (oxygen) sensor. On a test drive the driver may notice rough idling, a loss of power under acceleration, or an unusual exhaust smell. A thorough inspection should include a diagnostic scan for sensor codes, a visual check of exhaust pipes and muffler for cracks or rust, and a functional test of the lambda sensor and fuel injection system. The rear direction indicator will require verification of the bulb, socket and wiring continuity, while the wiper inefficacy suggests worn blades, a weak motor or a compromised linkage; these should be tested by operating the wipers at various speeds and inspecting the blade condition and arm movement. Given the vehicle’s age and low utilisation, the buyer must also examine age‑related wear items. Tyre sidewalls should be inspected for cracking, dry rot or uneven wear that can arise from prolonged storage; tread depth must still meet legal limits. Suspension bushes, ball joints and rubber mounts are prone to hardening and should be checked for play or clunking when the car is pushed over bumps. Brake discs may exhibit surface rust or glazing, and calipers should be examined for sticking pistons. The 12 V battery is likely to have reduced capacity after decades of intermittent use and should be load‑tested. Finally, all fluid reservoirs – engine oil, coolant, brake fluid and gearbox oil – should be sampled for colour, smell and level, and replaced if they show signs of degradation, as calendar‑based fluid ageing can compromise component longevity even in low‑mileage cars.
