2018 SEAT Arona 1.0L Petrol · BD18 ACO

The most recent MOT on 7 April 2026 recorded a Pass, but it was accompanied by a series of advisories and a separate failure for the outer track‑rod‑end ball‑joint dust covers, one of which was classified as a major defect. Over the past five years the record shows a steady accumulation of minor items – frayed rear‑seat‑belt webbing, deteriorating rear‑plate lettering, rear‑disc scoring and thin front‑pad wear – and the appearance of new concerns such as a nail in the nearside rear tyre and progressive side‑wall cracking. The emergence of the ball‑joint dust‑cover damage in the latest test marks a step down in condition, indicating that the overall maintenance trend is beginning to worsen rather than improve. With only 32,168 mi on the clock after eight years, the vehicle averages just over 4,000 mi per annum, well below the typical UK usage of 8‑10 000 mi per year. This low‑mileage profile suggests the car has spent considerable periods stationary, which can be as detrimental as high mileage because components age and seals dry out even when not driven. The modest mileage does not, however, eliminate wear on consumables such as brake discs, pads and tyres, all of which show age‑related degradation in the MOT notes. A prospective buyer should give particular attention to the rear‑seat‑belt assembly; any fraying or damage to the webbing can compromise restraint performance and should be replaced promptly. The rear brake discs are already scored on both faces and, while not yet weakened, are likely approaching the end of their service life – a resurfacing or replacement is advisable within the next few thousand miles, especially if you hear a faint pulsation or shudder when applying the brakes. Front brake pads are reported as thin, so expect a replacement soon; monitor for any grinding noises or a rise in pedal travel. The nearside rear tyre carries a nail and shows side‑wall cracking, both signs that the tyre is perishing and should be swapped for a fresh set to avoid sudden loss of pressure. Finally, the damaged dust covers on the outer track‑rod ends indicate that dirt can infiltrate the ball joints; check for any play or clunking when steering at low speed and consider fitting new dust covers and, if any play is detected, replacing the ball joints themselves. Given the vehicle’s age, a thorough age‑related inspection is essential. Verify the condition of the battery, looking for sulphation or reduced cranking power, and have its charge capacity tested. All fluids – brake, coolant, power‑steering and gearbox – should be examined for colour, level and signs of contamination, with a full brake‑fluid change recommended at least every two years. Inspect the suspension bushes, coil springs and anti‑roll bars for cracks, corrosion or excessive movement, and look under the chassis for any rust on the sub‑frame or mounting points that could affect structural integrity. Confirm that the timing chain (the ARONA uses a chain rather than a belt) has been serviced according to the manufacturer’s interval and that the service book contains stamps for regular oil changes. Finally, ensure the registration plate is legible, the TPMS indicator functions correctly, and all exterior lighting is operational before committing to purchase.
