2001 Jaguar XJ 3.2L Petrol · Y338 CDU

The Jaguar XJ presents a broadly stable but corrosion-prone roadworthiness profile. The most recent test on 31 August 2021 at 138,171 miles returned a pass with only split front suspension ball joint rubber gators advised, and no fresh failures logged since the 2019 rejection. Structural and suspension faults flagged earlier were either repaired or contained, though the underlying body corrosion noted in 2020 remains a standing concern rather than a cleared defect. Recorded mileage shows light use for a 25-year-old vehicle, totalling just 138,171 miles or roughly 5,527 per year. The gap between the 2017 test at 132,921 miles and the 2021 test at 138,171 miles covers only 5,250 miles across four years, implying long standing periods that accelerate rust yet spare drivetrain wear. Prior to that, annual increments from 2017 to 2019 stayed near 1,200 to 2,400 miles, confirming a consistently low-activity ownership pattern rather than sporadic high-load driving. A buyer should physically inspect the front suspension arm ball joint dust covers and mounting areas, as the 2019 failure cited excessive corrosion at the offside front lower mounting reducing structural strength, later downgraded to general body corrosion in 2020. The 2019 emission failure on CO after second fast idle and an inoperative engine MIL suggest past fueling or sensor faults that may recur if the cat or lambda sensors degrade. Rear wheel bearing play noted in 2018 and inner wing corrosion from 2017 warrant a ramp check for bearing noise and wing rot. Given the 2021 pass is nearly five years old relative to today's date of 17 July 2026, the vehicle requires a fresh MOT before any purchase. The recurring ball joint and structural corrosion advisories across 2019 to 2021 show the previous owner addressed hard failures but left consumable gaiters and body rust untreated, a pattern of minimal-intervention upkeep.
