2017 Peugeot 308 1.2L Petrol · LS17 XFL

A chronic pattern of exhaust system deterioration defines the mechanical profile of this 2017 Peugeot 308. Across four consecutive MOT tests spanning 2022 through 2026, advisories relating to exhaust integrity have appeared repeatedly, beginning with rear mounting defects noted in both 2024 and 2025, and culminating in a minor exhaust gas leak from a cracked central section at the most recent test on 15 June 2026. While each individual advisory was considered insufficient to fail the vehicle, the recurrence over successive years indicates progressive wear of the exhaust system rather than isolated damage. Underlying this exhaust pattern, brake disc advisories on both rear wheels have also surfaced consistently, with pitting and scoring on the nearside and offside rear discs flagged in both 2023 and 2024, pointing to brake friction surface wear that has remained a chronic concern across multiple inspections. Mileage of 69,121 recorded miles over a nine-year life equates to an average of roughly 7,680 miles annually, placing this vehicle firmly within the typical usage band for its age and likely reflecting a mix of urban commuting and moderate distance driving. The MOT history demonstrates a consistent annual testing pattern with no multi-year gaps, indicating the vehicle has remained in regular service throughout its life rather than experiencing any extended periods off the road. This continuity of use is mechanically significant because it suggests steady rather than intermittent wear on consumables, and it rules out the particular risks associated with prolonged standing, such as seized brake calipers, corroded brake discs, or deteriorated suspension bushes from lack of loading cycles. The mileage progression appears proportionate and stable, with no evidence of clock irregularities or unusual jumps between test entries. For a prospective buyer, the exhaust system warrants immediate and close physical inspection prior to purchase. With four years of progressive advisories culminating in a recorded crack, the central exhaust section should be examined on a cold start for audible ticking or hissing from the underbody, and the mounting rubbers should be checked visually for cracking, tearing, or complete detachment. A service replacement of the affected section is likely required imminently. The rear brake discs, flagged for pitting and scoring in consecutive years, should be inspected for ridge formation at the outer edge of the friction surface, which would indicate the discs are approaching minimum thickness and may require machining or replacement alongside fresh rear pad sets. On a test drive, listen for any knocking from the rear under braking, and feel for vibration through the brake pedal or steering wheel, which could indicate warped or excessively worn discs now beyond safe service limits. The wheels also merit careful attention during any pre-purchase evaluation, given that two inner road wheels were flagged in the 2023 test as slightly distorted. A buyer should road test the vehicle at motorway speeds to detect any steering wheel vibration, imbalance, or tracking pull that may have developed since that advisory was recorded, and the wheels themselves should be visually inspected for lateral run-out or visible deformation of the rim flange. The front and rear brake pads, noted as wearing thin in the 2022 test, are unlikely to have been replaced solely on advisories and should have been monitored, so current pad material thickness should be verified with a direct inspection through the caliper window. Taken together, the advisory record points to a vehicle that has passed its tests consistently but carries a predictable maintenance backlog centred on the exhaust and rear braking system, making a pre-purchase mechanical inspection and likely exhaust replacement the most pressing priorities before committing to purchase.
