2017 Dacia Logan 1.5L Diesel · P28 YAH

A pattern of recurring major failures on the 2017 Dacia Logan defines its MOT history, with repeated issues to headlamp aim, wiper performance and a constant‑velocity joint boot surfacing in the last two years. The most recent test on 11 September 2026 recorded a pass with no defects, indicating that the faults flagged on 10 September 2026 – headlamp aim too high, inoperative levelling device, ineffective nearside and off‑side wipers and a split CV‑joint boot – were remedied before the final assessment. Earlier in 2025 the car also failed for headlamp aim too low and a dangerous off‑side rear tyre lump, while advisories highlighted tyre cracking, oil seepage and sub‑frame corrosion, suggesting a history of intermittent but significant component wear. At 392,360 miles the vehicle has accumulated roughly 43,600 miles per annum, well above the typical UK average for a nine‑year‑old car. Such mileage accelerates wear on consumables and load‑bearing parts – suspension bushes, bushings, brake discs and pads, and drivetrain joints – and can exacerbate corrosion on structural elements. The MOT record shows no long gaps between tests, implying the car has been regularly presented for inspection despite the high mileage, but the sheer distance travelled raises the probability of hidden fatigue in the suspension and steering linkages and increased likelihood of oil‑related leaks. When inspecting the car, verify that both headlamps illuminate symmetrically and within legal limits; any persistent mis‑aim can indicate alignment issues or deteriorated mounting hardware. Test the wipers at low and high speeds to ensure full sweep coverage and adequate blade contact, as ineffective clearing was recorded as a major fault. Examine the rear tyres for any bulges, cracks or uneven wear, particularly on the off‑side rear where a structural lump was previously deemed dangerous; listen for thumping or vibration over road imperfections that may betray a compromised tyre or a failing CV‑joint boot. A visual check of the CV‑joint boot on the off‑side front drive shaft should reveal any splits or ingress points that could allow dirt and moisture to damage the joint. Finally, inspect the front and rear sub‑frames for surface rust, especially in wheel arches and under‑body areas, as both were flagged as corroded but not yet structurally weakened. Look for fresh oil stains beneath the engine and gearbox to confirm whether the previously noted oil leaks have been resolved; persistent seepage can affect seals and bearings over time. Given the high mileage and the recurrence of these specific defects, a thorough mechanical appraisal – including suspension bush wear, brake disc thickness and drivetrain joint integrity – is essential before committing to purchase.
