2011 Peugeot Expert 1.6L Diesel · WN11 AAO

The most recent MOT on 3 June 2026 was a Pass, albeit with several advisories concerning tyre tread depth, slight play in the front anti‑roll‑bar linkage, deteriorated constant‑velocity (CV) boot on the near‑side front drive shaft and a faulty off‑side registration‑plate lamp. Over the preceding three years the record shows a mixture of Passes and Failures, with recurring CV‑boot degradation, anti‑roll‑bar ball‑joint wear and lamp failures, and a single oil‑leak advisory that has persisted. While the vehicle has managed to clear the latest test, the pattern indicates a maintenance trend that is not improving; rather, the same components continue to be flagged and some have progressed from advisory to major status, suggesting that remedial work has either been deferred or only partially addressed. At 150,497 mi the Expert averages just over 10 000 mi per annum, which is typical for a 2011 model. The mileage does not suggest any periods of prolonged inactivity that would raise concerns about tyre perishing or battery neglect, nor does it indicate unusually high annual use that would accelerate wear beyond normal expectations. Consequently, wear on consumables such as tyres, brakes and suspension components should be commensurate with the recorded distance, but the recurring advisories imply that certain items have been subjected to higher stress or have not received timely replacement. A prospective buyer should give particular attention to the front CV boots on both sides; the near‑side boot has been noted as severely deteriorated for several years and the off‑side boot was recorded as split in 2024. Inspect the boots for cracks, oil or grease leakage and feel for any play or clicking when the vehicle is driven at low speed and the steering is turned sharply – symptoms of a failing CV joint. The anti‑roll‑bar ball joints on both the near‑side front and off‑side front have been flagged for slight to excessive play; a clunk or knock when traversing bumps or during cornering would confirm wear and may necessitate replacement of the bushings or the ball joint itself. Tyre tread on the near‑side rear and off‑side front is already close to the legal limit, so a full tyre inspection for uneven wear patterns, sidewall cracking and depth measurement is essential, and budgeting for a set of new tyres is prudent. Verify that all external lamps – headlamps, registration‑plate lamps and the central stop lamp – operate correctly, as failures have previously caused a major MOT failure. Beyond the recurring items, a thorough age‑related check is advisable. Examine the brake discs and pads for surface rust, glazing or uneven wear, and test for any pulsation or shudder under braking. Inspect the battery terminals for corrosion and assess the battery’s state of charge, especially if the vehicle has spent time idle. Check the engine oil level and condition, and locate the source of the oil‑leak advisory – common culprits include the valve‑cover gasket or oil filter housing – to avoid future loss of oil pressure. Finally, confirm that the service history reflects regular oil and filter changes, coolant flushes and timing‑belt or chain service at the intervals recommended for the 2.0 L diesel, as these calendar‑based services are critical for reliability in a vehicle of this age.
