2010 Citroen C5 2.0L Diesel · BN60 AAZ

A persistent pattern of front suspension wear dominates the mechanical history of this 2010 Citroën C5, with the front suspension arm pins or bushes flagged at three consecutive tests between 2023 and 2025 and escalating to major failure category defects in February 2025, when both nearside and offside components were recorded as excessively worn and contributed to a fail. The advisories issued at the December 2025 test confirm the components were renewed or repaired in the intervening ten months, but that the replacement items are already showing early signs of wear again, which raises a genuine concern about the underlying state of the front subframe, mounting points, or the quality of the rectification work. This is not a record of isolated advisories but a recurring, bilateral, worsening defect pattern that warrants close physical inspection before commitment. The most recent pass on 16 December 2025 also noted pitted and scored front brake discs, indicating the braking components are approaching the point at which machining will no longer be viable and replacement becomes necessary. With 126,568 miles accumulated over roughly sixteen years, the vehicle is running at approximately 7,910 miles per year, which is broadly consistent with average usage for a car of this age. There are no multi-year gaps in the MOT record that would suggest extended periods off the road, and the test history shows annual or near-annual presentation from 2023 onwards, which means the recorded wear pattern reflects a car in active service rather than one subject to long lay-ups. The mileage places this C5 firmly into high-wear territory for its component group, particularly for suspension bushes, dampers, brake discs, and engine ancillaries, and the advisory trail supports this: front brake disc pitting has been flagged at both 2023 and 2025 tests, and an oil leak, albeit not excessive, was noted in September 2023. Sustained use at roughly eight thousand miles annually is generally sufficient to keep lubricants circulating and prevent the deterioration associated with standing vehicles, but it also means consumables wear at a predictable pace. For a prospective buyer, the priority on any inspection must be the front suspension assembly. On a test drive, listen for clonking or knocking from the front end over speed bumps, uneven road surfaces, and during full-lock manoeuvres at low speed, as these are the classic symptoms of worn lower arm bushes and anti-roll bar drop links on the C5 platform. With the car parked and the front jacked, attempt to rock each front wheel vertically and fore-and-aft at the three o'clock and nine o'clock positions to detect any free play in the wishbone bushes; even minor movement at this mileage should be regarded as the likely source of further advisories. Brake pedal feel should be firm and progressive, and any judder under braking points directly to the pitted discs already recorded, while heavy or erratic pedal travel could indicate the caliper guide pins have seized, a common C5 failure that is rarely flagged in MOT data but frequently found during physical inspection. The oil leak noted in 2023 deserves a physical check as well. With the engine warm, inspect the underside for any fresh oil film around the cam cover gasket, sump, and front crankshaft seal, and note any residue on the lower bellhousing area which can indicate a rear main seal issue on higher-mileage units. The headlamp aim defect that caused the February 2025 failure should be confirmed as a proper repair, as incorrect beam pattern on the C5 often stems from worn or cracked headlamp mounting brackets rather than a simple adjustment. Finally, examine all four tyres for uneven shoulder wear, which on this vehicle typically points to worn suspension geometry components or alignment issues, and verify the 225/55/17 specification against the offside rear advisory so a direct comparison of remaining tread depth can be made. Given the recurring front suspension defect, the brake disc wear pattern, and the oil leak history, a pre-purchase inspection by a specialist familiar with hydropneumatic or conventional C5 suspension is strongly advisable before proceeding.
