2015 Peugeot Expert 2.0L Diesel · ST15 EVH

The most recent DVSA examination took place on 3 December 2025, resulting in a pass with three advisories noted: both rear direction indicators are slightly discoloured, and an oil leak is present though not currently excessive. Looking back over the recorded history, the maintenance trend is mixed but carries concerning indications. The vehicle has suffered four major failures in recent years, with three of those occurring within a two-week window in December 2023 and a further failure in December 2024. The 2023 failures centred on split or insecure constant velocity boots on both front drive shafts, insecure exhaust system mounting, and a registration plate lamp defect, while the 2024 failure involved the supplementary restraint system warning lamp indicating a fault and an inoperative central stop lamp. Although the vehicle has subsequently passed its tests, the recurrence of drive shaft boot failures and the appearance of an airbag system warning suggest underlying mechanical or electrical issues that may not have been fully resolved at the time of testing. The pattern of advisories relating to oil leaks in both 2023 and 2025 indicates this is a chronic condition rather than a newly developed defect. The recorded mileage of 148,022 against an approximate age of eleven years yields an annual accumulation of roughly 13,457 miles, which is notably high for a vehicle of this type and age. This level of usage implies substantial wear on all major mechanical systems, including the clutch, turbocharger, drivetrain, suspension, and braking components. The MOT records show consecutive annual tests from 2022 onwards with no significant gaps in mileage accumulation, indicating the vehicle has been in regular service rather than standing idle for extended periods. Continuous high-mileage use typically accelerates wear on timing chains, dual mass flywheels, turbo bearings, and suspension bushes, and it is reasonable to expect that several major service items may now be due or approaching due, particularly given the age of the vehicle. For a prospective buyer, the recurring drive shaft constant velocity boot failures warrant immediate and thorough inspection. The boots protect the CV joints from contamination by dirt and water, and once split, joint deterioration progresses rapidly, leading to clicking noises on full lock turns, vibration through the transmission, and ultimately joint replacement rather than simple boot refurbishment. On a test drive, listen for clicking or knocking from the front wheels when manoeuvring at low speed with steering at full lock, and inspect the boots visually for fresh grease deposits, cracking, or perished rubber. The 2024 supplementary restraint system warning lamp fault is a serious concern that requires diagnostic interrogation to determine whether it relates to a sensor issue, a wiring fault, or an actual airbag or pretensioner failure. Any indication that the warning lamp has reappeared since the test should be treated as a significant safety issue demanding professional investigation before purchase. The chronic oil leak noted across multiple tests should be inspected at ground level beneath the engine and gearbox for fresh staining, and on a test drive the driver should monitor for any warning lights, unusual smells, or visible smoke from the engine bay when warm. Given the high mileage and vehicle age, particular attention should also be paid to the condition of the timing chain and associated tensioners, the turbocharger for excessive play or whistling, and the dual mass flywheel for signs of clutch shudder or rattling on idle. The front brake pads were noted as wearing thin in early 2023, and at this mileage it would be prudent to verify current brake pad material thickness, disc condition including lipping and hot spots, and the operation of the calipers for binding or sticking. The exhaust system has been flagged as insecure in previous tests, so the mounting rubbers, hangers, and any flex sections should be physically checked for security. Finally, confirm the service history documentation, paying particular attention to evidence of recent cambelt or timing chain replacement, coolant renewal, automatic or manual transmission fluid changes, and brake fluid replacement, as these calendar-based services are often neglected on high-mileage commercial vehicles.
