2010 Jaguar XF 3.0L Petrol · SM10 AAU

The most recent MOT on 4 March 2026 was passed, but it was accompanied by a suite of advisories covering corrosion of all four brake pipes, side‑wall cracking on the off‑side rear tyre and a repeat of the same tyre‑perishing warnings seen in earlier tests. Over the last two years the pattern has been one of accumulating corrosion‑related notes – brake hose ferrules, brake pipe metal and the rear sub‑frame mounting – together with progressive wear on the front inner brake disc and recurring tyre side‑wall damage. While the vehicle continues to meet the statutory pass criteria, the defect trend is clearly moving towards a worsening state of corrosion and tyre degradation rather than stabilising. At 22 552 miles the Jaguar XF averages roughly 1 410 miles per annum, which is exceptionally low for a sixteen‑year‑old saloon. Such limited mileage often reflects long periods of inactivity or very gentle use, both of which can exacerbate age‑related deterioration such as rubber perishing, metal corrosion and fluid breakdown. The low annual run‑rate does not offset the calendar wear on components that are exposed to the elements, and it suggests that any consumables – tyres, brake linings, hoses and the battery – may be nearer the end of their service lives than the mileage alone would indicate. A prospective buyer should give particular attention to the brake system. Inspect each brake pipe for rust, pitting or thinning and verify that the protective grease coating is intact; any visible corrosion should be remedied by replacement of the pipe and a thorough bleed of the system. The brake hoses, especially the ferrules noted as slightly corroded, should be examined for cracking or hardness and replaced if any signs of deterioration appear, followed by a complete fluid change to remove moisture and prevent further corrosion. The front inner disc, flagged as worn, pitted and scored, should be measured for thickness; if it is approaching the minimum legal limit or shows uneven scoring, replacement of the disc (and possibly the pads) will be required to avoid brake shudder or reduced stopping performance. Tyre side‑wall cracking on the off‑side rear and earlier notes on the front tyres indicate perishing; the tyre tread may still be acceptable but the compromised sidewalls can lead to sudden failure, so all four tyres should be examined for dry rot, cracks and bulges and replaced if any defect is found. Beyond the brakes, the rear sub‑frame mounting area showing corrosion warrants a visual inspection for rust flaking or structural weakening; any excessive corrosion should be treated or the mounting panel repaired. Given the vehicle’s age and low mileage, check the 12‑volt battery for sulphation and verify its cranking voltage, as a long‑standing idle can leave the battery weak. Examine the suspension bushings, ball joints and shock absorbers for any creaking or uneven wear, especially after a short test‑drive that includes bumps and cornering – any clunk or vibration may point to deteriorated bushings. Finally, confirm that the coolant, engine oil and transmission fluid have been changed according to the service schedule rather than mileage, and look for any signs of leaks around the engine bay, exhaust and underbody, as time‑based fluid degradation can cause seal failure even on low‑kilometre cars.
