2004 SEAT Leon 1.8L Petrol · OV04 XTH

The most recent MOT, dated 19 February 2022, was passed but recorded a number of advisories covering the exhaust, a front oil seep, front brake disc wear, and tyre wear on the nearside rear. Earlier in the record the vehicle suffered a failure in 2016 for a broken rear coil spring and a CV‑joint gaiter breach, and again in 2017 for multiple lighting faults and a similar CV‑joint issue. Since the 2018 MOT the car has passed without any recorded failures, with only advisory items appearing in 2019, 2021 and 2022. This trajectory indicates a generally improving maintenance pattern, suggesting that the most serious faults have been addressed and the current state is largely stable, albeit with a few wear items that merit attention. At 123,718 miles on a 2004 model the average annual mileage works out at roughly 5,600 mi per year, which is considerably below the typical 10,000‑12,000 mi expected for a vehicle of this age. The low utilisation points to either light daily use or extended periods of storage. While reduced wear on engine, transmission and suspension components is a benefit, prolonged standing can accelerate rubber ageing, battery depletion and corrosion of brake discs and calipers. The modest mileage also means that consumables such as tyres may be nearing the end of their calendar life even if tread depth appears acceptable. Prospective buyers should give particular focus to the exhaust system, checking for any audible hissing or sulphur‑smelling fumes at the rear and confirming that the muffler and pipe joints are free of cracks or rust. The front oil leak noted in 2022 should be inspected for a steady drip around the valve cover or oil filter housing; excessive oil loss can lead to low oil pressure and engine wear. The front brake disc was flagged as worn, so a visual inspection of disc thickness and surface condition is essential, and the rear brake pads were reported thin in 2019 – the brake pedal should feel firm without pulsation, and any shudder when applying the brakes may indicate disc or pad wear. Tyre wear on the nearside rear edge and the previous near‑limit wear on both front tyres suggest possible alignment or suspension issues; a professional wheel‑alignment check and a thorough examination of the front ball‑joint dust covers, suspension arm bushings and CV‑joint boots for cracks, grease leakage or excessive play are advisable. Any clunking or knocking when steering or over bumps would confirm deterioration in those areas. Given the vehicle’s age and low mileage, time‑related maintenance is as important as mileage‑related wear. Verify that the 12‑volt battery has been tested recently and is not approaching the end of its service life, as batteries left idle for long periods can fail unexpectedly. Inspect the tyre sidewalls for cracking, dry rot or age‑related perishing – the DOT code should indicate whether the tyres are older than six years, in which case replacement is prudent regardless of tread depth. Examine the brake discs for surface rust and ensure the calipers move freely without binding, a common issue on cars that sit. Finally, confirm that the coolant, brake fluid and engine oil have been changed within the recommended intervals, as fluids degrade with time even on low‑use vehicles; any milky coolant, discoloured brake fluid or oil with a burnt smell should trigger a service before purchase.
