2022 Peugeot 5008 Allure Premium B-HDI SS A 1.5L Diesel · MD71 AAV

The mechanical story for this 2022 Peugeot 5008 is one of recent, localised powertrain wear rather than a systemic pattern of decline. The most recent test on 15 January 2026 returned a clean pass with no advisories or defects recorded, following a failure on the immediately preceding day caused by a torn constant velocity boot on the offside front driveshaft. The previous test in January 2025 also passed without any recorded issues, and there are no advisories anywhere in the documented history. A split CV boot is a relatively common wear item on front-wheel-drive and four-wheel-drive vehicles operating in the UK climate, where salt, standing water, and undertray grime accelerate rubber degradation. Because the boot was replaced and the subsequent test produced no advisories, the immediate concern has been resolved at the point of test, but the underlying joint grease contamination and potential water ingress from the period prior to repair warrant close physical inspection before purchase. Mileage accumulation on this 5008 is broadly consistent with what one would expect for a four-year-old family SUV in the UK. At 41,772 miles recorded over four years, the vehicle is averaging roughly 10,400 miles annually, which is a typical figure for a car of this type used for mixed commuting, school runs, and longer family journeys. There are no unexplained gaps in the testing record and no evidence of prolonged off-road periods or sporadic, irregular use that might point to standing-start corrosion or dried-out drivetrain seals. This steady annual usage is mechanically favourable, as it indicates regular warm-up cycles, consistent brake and suspension loading, and a lower likelihood of the chronic oil leaks, seized calipers, and perished rubber components that typically afflict vehicles left standing for extended periods. The mileage itself is not yet at a point where major drivetrain servicing such as timing belt replacement would be imminent on most HDi variants, though the exact service schedule for this specific B-HDi unit should be verified against the manufacturer documentation. For a prospective buyer, the priority on inspection is the offside front driveshaft assembly and its surrounding components, given the documented CV boot failure. On a test drive, listen carefully for any clicking or knocking from the offside front wheel area when turning at low speed, particularly when entering a parking space or performing a full-lock turn in either direction, as this would indicate that the replacement boot was fitted after the joint grease had already been compromised. Vibrations through the steering wheel or a humming noise that changes with road speed can also point to a worn CV joint. The vehicle should be raised on a ramp or examined on a lift to confirm that the replacement boot is correctly seated, its retaining clips are intact, and there is no fresh grease leakage around the joint. Beyond the driveshaft, attention should be paid to the front suspension components, as the constant velocity joint failure is often associated with aged suspension bushes allowing excess wheel travel and impact loading on the driveshaft. Additional checks on the test drive should focus on the symptoms commonly associated with the recorded mileage and the diesel powertrain. The 5008's HDi engine is known for EGR valve and turbo actuator wear at this sort of mileage, so the buyer should look for any loss of power under acceleration, excessive black smoke under load, or an illuminated engine management light. The automatic transmission, if specified, should be checked for smooth, timely gearchanges with no flare between ratios or harsh downshifts on light throttle. Brake feel should be firm and progressive, with no pulling to either side under moderate braking, and the steering should remain precise with no vagueness around the straight-ahead position. Finally, a thorough underbody examination for any corrosion on the subframe, brake lines, and suspension arms is advisable, as diesel variants in this age bracket frequently operate in conditions conducive to surface oxidation, even where no advisories have yet been recorded.
