2018 Dacia Logan 0.9L Petrol · LL18 EDF

A chronic front brake disc wear issue defines the mechanical history of this 2018 Dacia Logan, with advisories for worn, pitted, or scored front discs recorded at four of the seven MOT tests spanning 2021 through 2026. The most recent examination on 26 June 2026 reflects this ongoing concern, passing with the same advisory still in place after a failed attempt on the same date caused by dangerous headlamp defects on both sides and a non-functional nearside dipped beam. This pattern of persistent front brake disc deterioration, flagged consistently across multiple annual tests, points to a component that has reached an advanced stage of wear and will likely require replacement imminently. While the front brake discs have been wearing steadily for several years without yet crossing into a fail category, the recurrence of the same advisory demonstrates that the issue has not been resolved through maintenance or component renewal. The vehicle has covered 92,574 miles over eight years, equating to approximately 11,572 miles per year, which sits broadly in line with typical annual usage for a car of this age. There are no significant gaps in the testing history, with seven consecutive annual tests recorded from 2021 to 2026, suggesting consistent use rather than extended periods off the road. Mileage accumulation between tests appears steady, generally in the range of ten to fifteen thousand miles per year, which is the kind of usage pattern that produces steady wear on consumables such as brake components, tyres, and suspension bushes. This regular driving profile aligns with the recurring brake disc advisories, as sustained urban and mixed driving accelerates wear on the front braking system, particularly if the vehicle is frequently used in stop-start traffic. A prospective buyer should treat the front brake discs as the primary mechanical concern and budget for replacement, including both discs and likely pads, given the four-year history of advisories pointing to the same components. During a physical inspection, the front discs should be examined for visible grooving, lipping on the outer edge, and uneven surface wear, while a test drive should focus on any judder or vibration through the brake pedal under firm application. The 2026 failure related to headlamp aim and a non-functional dipped beam on the nearside should also be verified as rectified, with checks carried out in dark conditions to confirm both headlamps are operating correctly and aligned within legal tolerances, alongside confirmation that the registration plate lamp issue from 2024 has been resolved. Given the recurring nature of the brake disc wear and the headlamp electrical faults recorded, a pre-purchase inspection by a competent mechanic is advisable, with particular attention to the front brake calipers for any signs of binding or sticking pistons, which can accelerate disc wear unevenly. The tyres should also be inspected closely, as a 2022 advisory noted cracking and perishing in the tread pattern on both rear tyres, and any similar deterioration now would indicate ageing rubber compound that warrants replacement regardless of remaining tread depth. Suspension components, including front wishbones, anti-roll bar links, and steering rack gaiters, should be examined for wear given the vehicle's mileage, and the test drive should include assessments over uneven road surfaces to detect any knocking, clonking, or loose handling characteristics that would suggest worn bushes or dropped linkages.
