2015 Peugeot Expert 2.0L Diesel · WN65 KUG

The 2015 Peugeot Expert most recently passed its MOT on 8 April 2026 with only two minor advisories recorded against the offside front drive shaft, both concerning severely deteriorated constant velocity gaiters on the inner and outer joints. While these were classified as Minor defects at the time of test, meaning the vehicle met the minimum legal standard, they represent a recurring pattern that has appeared at every test since March 2025 and warrants close attention. The earlier 2025 test also recorded an advisory oil leak, again described as not excessive, and a minor defect on the nearside rear registration plate lamp. The overall trend shows a stable rather than worsening maintenance picture, but the persistence of gaiter deterioration across consecutive tests suggests the issue has not been rectified and could progress to a future failure if grease loss occurs and contamination follows. The 2021 and 2023 failures, which involved lighting faults, wiper and washer functionality, and most seriously a dangerously detached lower suspension arm ball joint alongside severely worn brake pads, are now several years in the past and appear to have been addressed, though they do underline a need to verify the quality of subsequent repair work. Recorded mileage stands at 104,650 miles across an estimated eleven years of age, giving an annual average of roughly 9,514 miles, which is broadly typical for a commercial or multi-purpose vehicle of this type. There is no evidence in the MOT record of extended standing periods or unusually rapid accumulation between tests, with the mileage progression appearing consistent throughout the documented history. For a diesel Peugeot Expert of this vintage and workload, this kind of mileage is not excessive and the drivetrain, clutch and turbo components should have reasonable remaining service life provided they have been correctly maintained. Buyers should however confirm that the engine oil and filter, fuel filter, and timing belt or chain service intervals have been observed strictly to manufacturer schedule, as missed intervals on high-load diesel engines frequently lead to premature wear of injectors, turbo bearings and dual mass flywheels. Given the recurring constant velocity gaiter defects, particular attention should be paid to the offside front drive shafts during any physical inspection. Split or perished boots allow grease to escape and allow water and road debris to enter the joint, accelerating wear of the CV internals. Listen on a test drive for a clicking or knocking noise from the front when turning at full lock, particularly in reverse, and feel for any vibration through the steering or under acceleration, both of which are classic symptoms of an advanced CV joint failure. Replacement boots at this stage are relatively inexpensive, but a complete joint replacement if neglected can become costly. The noted oil leak should be located and assessed; common sources on this model are the sump pan gasket, timing cover, turbo oil feed, and injector seals, and a drip tray examination at the previous parking location can help confirm severity. Any staining on the engine block, dampness around turbo plumbing, or blue smoke on start-up or under load would suggest the leak is progressing. Beyond the recorded advisories, a prospective buyer should carry out a range of age and mileage-appropriate physical checks. Examine the tyres closely for uneven shoulder wear which can indicate worn suspension bushes or alignment drift, but also check the sidewalls for perishing and cracking consistent with a vehicle over five years old, as rubber degrades with age regardless of tread depth. Inspect the brake discs for lipping and surface corrosion, paying particular attention to whether the offside front caliper is binding following the heavy pad wear previously recorded, which can manifest as pulling under braking or a hot wheel after driving. Verify the condition of the lower suspension arms, anti-roll bar links and drop links, as the 2021 dangerous failure indicates this vehicle has been subjected to rough road surfaces or heavy loading in its past. Confirm 12V battery health, as commercial vehicles with frequent short trips and stop-start cycles strain battery life, and ensure that brake fluid, coolant and transmission oil have been refreshed within their calendar intervals. Finally, review the service book stamps or digital records thoroughly to ensure the timing belt, water pump, clutch and dual mass flywheel have all been attended to at the correct intervals for a diesel van of this mileage.
