2008 Mazda MX-5 2.0L Petrol · ST56 ABB

The September 2025 test at 109,567 miles returned a pass, yet the maintenance trend has worsened sharply over the last two cycles. A clean pass in September 2023 at 95,331 miles gave way to a dangerous failure in September 2024 at 101,154 miles, where the nearside front upper drag link end ball joint posed a detachment risk. That test also recorded three tyres at the legal limit, a noisy exhaust, intermittent lighting faults and persistent offside front brake binding. The most recent certificate clears the dangerous items but carries forward the binding brake and a worn, pitted offside front disc, while adding severely deteriorated dust covers on both rear upper suspension arm ball joints. Mileage accumulation averaged roughly 6,000 miles per year until 2023, consistent with the 18-year age profile. The interval between the 2024 and 2025 tests saw that rate climb to over 8,400 miles, suggesting a change in usage intensity. No significant gaps appear in the annual test cycle; the record runs unbroken from 2015 through 2025. A 2019 emissions failure involving the malfunction indicator lamp and excessive CO and hydrocarbon readings was rectified for the retest two days later, and no further engine management faults appear thereafter. Recurring faults concentrate on the offside front braking corner and the steering and suspension joints. The offside front brake has shown binding at every test since 2020, accompanied by a disc that remains worn and pitted despite passing the minimum thickness check. Dust cover deterioration has migrated from the front anti-roll bar links in 2020 to the track rod ends in 2024 and now the rear upper suspension arm ball joints in 2025. The exhaust note has been flagged as excessive since 2024, and the 2024 tyre advisories indicate the previous owner ran the rear axle and offside front down to 2 mm before replacement. A pre-purchase inspection must verify the offside front caliper slides and disc condition, confirm the rear upper ball joints exhibit no play beyond the dust cover damage, and check the exhaust system for holed silencers or cracked flexi-pipes. Steering rack gaiters and track rod ends warrant close scrutiny given the history of dust cover failure and the 2024 drag link wear. The binding brake and pitted disc suggest a seized caliper piston or slide pins; budget for a caliper overhaul or replacement alongside a disc and pad set on that corner.
