2014 Land Rover Range Rover Sport 3.0L Diesel · FN14 UAC

The defining mechanical story for this Range Rover Sport is a chronic pattern of front-end tyre wear and front suspension bush wear that has surfaced repeatedly across the MOT record, alongside persistent rear differential oil seepage. The most recent test on 2022-11-30 was a pass, but it carried advisories for both front tyres wearing close to the legal limit on their edges, the same wear pattern that was flagged on the offside rear in late 2020 and on both front tyres with sidewall cuts in mid-2019. Front suspension arm pin or bush wear has appeared twice as an advisory, on 2022-03-03 for both sides and on 2020-11-07 for the nearside radius arm specifically. A single failure on 2020-11-07 included a dangerous nearside rear tyre with tread below 1.6mm containing a nail, a nearside front tyre with sidewall damage exposing ply or cords, ineffective wipers, and an insufficient washer, while an earlier 2019-05-31 failure was limited to a washers deficiency under the old pass-and-reason criteria. Across six test events there is one outright failure with a dangerous defect and a further six advisories, which indicates that while the vehicle has never been refused a certificate for structural or brake integrity, the consumable and chassis-bush wear rate has been consistently elevated rather than improving. Mileage accumulation is roughly typical for the age at around 9,464 miles per year, but the timing of the recorded tests suggests some irregularity in usage or testing compliance. There are notable gaps between tests, including a stretch from May 2018 to May 2019 and another from November 2020 to March 2022, which could reflect periods of low use, SORN status, or simply missed test deadlines. With 113,574 miles accumulated over roughly eight years of recorded testing, the average annual figure masks the uneven pattern, and any buyer should ask for a full mileage timeline to identify whether any single year produced rapid accumulation that would accelerate wear on the timing chain, automatic transmission, air suspension compressor, and transfer box internals, all known wear points on this generation of Range Rover Sport. The repeated rear differential oil leak advisory in 2018 and again in 2020, although described as not excessive, points to a seal that has been seeping over a prolonged period and warrants a physical underbody inspection rather than reliance on MOT observation alone. A prospective buyer should focus the physical inspection on the front suspension geometry, because the advisories specifically name radius arm and general suspension arm pins or bushes. With the engine running and the vehicle on level ground, listen for clunks or knocks from the front end when braking or driving over speed humps, and pay particular attention to vague wandering at speed or uneven tyre wear across the front axle, as both are classic symptoms of worn radius arm or upper and lower wishbone bushes on this chassis. The nearside front has been flagged more often than the offside, suggesting asymmetric wear, so check for uneven inner or outer shoulder wear on the front tyres and any signs of recent alignment adjustments. On the test drive, feel for any delay or harshness from the air suspension, knocking from the front air struts or compressor cycling excessively when stationary, and listen for any droning from the differential that might indicate the oil leak has progressed to a failing pinion seal. Given the rear tyre dangerous failure in late 2020 and the recurring front and rear edge-wear advisories, inspect all four tyres very carefully for age cracking in the sidewalls, as the 295/40 profile fitted to this vehicle is expensive to replace in matching pairs and uneven wear suggests underlying geometry or pressure issues rather than simple consumable replacement. Check the rear differential area for fresh oil residue on the undertray and on the lower suspension arms beneath the diff housing, and smell for warm gearbox or differential oil after a short drive. Verify operation of the wipers and washer system, as both have failed inspection twice, which on a 2014 model can indicate a failed washer pump, a blocked scuttle drain causing reservoir contamination, or worn wiper linkage bushes. Finally, confirm that all warning systems, four-wheel-drive selection, and Terrain Response modes function correctly, because the MOT record does not interrogate the transfer box, air suspension valve block, or electronic differentials, and these are areas where high-mileage Range Rover Sport vehicles commonly develop faults outside the scope of standard testing.
