2017 Ford Focus 2.3L Petrol · AT17 RST

The defining mechanical story across this Focus's MOT record centres on tyre integrity and front suspension hardware, with two outright failures and a recurring advisory trail flagging the nearside front tyre specifically across four consecutive test cycles. On 2023-09-20 the nearside front tyre was recorded with ply or cords exposed, a dangerous defect, on the same test that also produced a failure for an inoperative windscreen washer; the test was then re-presented the same day and passed with no advisories. The nearside front tyre has subsequently been flagged at both 2024 and 2025 tests for slight damage, and on the 2025-09-09 pass an exhaust noise advisory was also raised. Separately, in 2024 a minor defect was recorded for severe deterioration of the nearside front anti-roll bar linkage ball joint dust cover, and in 2021 an emissions test could not be completed due to a procedural fault. Against that, the intervening years of 2020, 2021, 2022, and 2023 each produced clean passes with no defects at all, so the pattern is not one of chronic deterioration but rather of intermittent, component-specific issues clustered around tyres, the anti-roll bar linkage, and exhaust integrity. With approximately 52,719 miles over a nine-year span, annual mileage averages around 5,858 miles, which is well below typical figures for a Focus of this vintage and points to either genuinely low use or extended periods of the vehicle standing off the road. The MOT cycle itself shows consistent annual testing from 2020 through 2025 without multi-year gaps, confirming the car has remained registered and presented for test each year, although a same-day re-test in 2023 produces a duplicate entry rather than additional mileage accrued. Lower annual mileage of this nature generally reduces wear on high-cycle components such as brake discs, clutches, and engine internals, but it can accelerate ageing of items that degrade through standing still, particularly brake calipers seizing, corrosion setting into brake pipes and underbody seams, and drying or cracking of rubber components like the anti-roll bar dust cover already noted on this car. For the anti-roll bar linkage that was flagged with a deteriorated dust cover in 2024, the buyer should focus on the physical joint itself rather than assume a new boot has rectified the issue, as the original defect suggests the ball joint may have been operating with compromised sealing and could now exhibit play. With the engine running on a level surface, listen for clonks or knocks from the front suspension when traversing speed bumps or potholes, particularly over the nearside, and feel for any vagueness or rattle through the steering wheel on uneven surfaces. During a test drive, perform several moderate braking stops from around 30 mph to assess for pedal judder, pulling to one side, or any binding sensation that could indicate seized caliper slides, a known concern on low-mileage vehicles. Inspect the nearside front tyre sidewall closely for any bulges, cracking, or scuff damage, and verify it is a recent production, as the same corner has produced advisories in three of the last four tests. Given the exhaust noise advisory recorded at the most recent test, the buyer should listen at idle and during light acceleration for any change in exhaust note compared to a known good example, paying particular attention to the front pipe, flexi joint, and rear silencer box for blowing sounds or rattles, and check the underbody for any visible soot staining or hangers that have detached. A thorough inspection underneath on a ramp is advisable to confirm the absence of corrosion on brake pipes, the subframe, and suspension mounting points, as low-mileage cars that see mainly short urban trips can still develop underfloor corrosion from damp storage conditions. Tyre condition across all four corners warrants measurement of remaining tread depth with a gauge rather than relying on visual judgement, as the 2023 test recorded both rear tyres worn to 3mm on the edges, suggesting an alignment or suspension geometry issue that may still be present. Finally, confirm the windscreen washer system is fully operational on both front and rear, and verify that the emissions testing apparatus can complete a full reading, given the 2021 inability to test.
