2005 Volkswagen Polo 1.2L Petrol · MJ55 BNN

A clear mechanical theme runs through the MOT record of this 2005 Volkswagen Polo: chronic front suspension wear, persistent exhaust issues, and a gradual decline in shock absorber condition. The most recent test on 19 October 2021 returned a pass with a single advisory noting light oil misting on the offside front shock absorber, but this same component was flagged with light misting as far back as December 2020, suggesting the seal has been weeping progressively rather than being rectified. Beneath the surface, the suspension subframe area tells a more concerning story. In December 2018 the vehicle failed its MOT on both front suspension arm rear bushes, recorded as excessively worn, and a minor advisory also noted a deteriorated offside front anti-roll bar linkage dust cover. The earlier December 2017 test flagged slight play in both front suspension arm rear bushes, indicating this was a developing problem that ultimately crossed the failure threshold a year later. While the post-2018 records do not re-flag the suspension arm bushes, replacement is plausible but cannot be confirmed from MOT data alone, and bushes of this design on a Polo of this age are a known wear item that warrants close physical inspection. Mileage accumulation is notably modest for a 21-year-old vehicle, with the last recorded odometer reading of 103,250 miles in October 2021 implying an average of roughly 4,900 miles per year over its lifetime. However, the MOT testing pattern itself tells a useful story about actual use. The car was tested in 2017, 2018, and twice in 2019, but then did not appear again until late 2020 and once more in October 2021, leaving a multi-year gap between 2012 and 2017 where no test data exists at all. Low annual mileage of this kind can mean reduced wear on high-mileage components such as the clutch, gearbox, and engine internals, but it also means the vehicle may have spent considerable periods standing, which is consistent with the corrosion advisories noted on the exhaust system and the suspension component wear that has still emerged despite limited road use. The 2019 failure for excessive carbon monoxide at idle further suggests the engine and exhaust were not being exercised regularly enough to keep catalytic converter efficiency within tolerance. For a prospective buyer, the front suspension is the single most important area to examine physically and on a test drive. With the offside front shock absorber having now been flagged for oil misting on two consecutive tests, it is reasonable to expect the damping is deteriorating, and a road test should include firm presses over speed bumps and undulating roads to listen for clonking from the front strut area and to feel whether the body takes more than one oscillation to settle. The front suspension arm rear bushes previously failed for excessive wear, so with the car on a ramp or with the wheels lifted, the arms should be physically checked for any free play or splitting, and the front anti-roll bar drop links should be inspected for play at the ball joints. On the test drive, listen for knocking or rattling over rough surfaces, particularly from the front end, and pay attention to vague or wandering steering, which can suggest worn bushes or link deterioration. The offside rear shock absorber was also flagged for light misting in 2018, so any bouncing or poor body control at the rear under braking or over bumps is worth noting. The exhaust system warrants equal scrutiny, given that advisories for a minor leak at the front flexi appeared in 2017, weak exhaust structure in 2018, and corrosion of the rear box in 2020. With the car cold-started, listen for any ticking or hissing from the front section that would indicate a failed flexi joint, and feel for any pulsing exhaust gases from underneath. With the engine running at idle, the tailpipe emissions smell should be neutral rather than overly rich or sulphurous, and a handheld lambda or emissions check can confirm whether the 2019 carbon monoxide issue has been resolved. The tyres noted as worn close to the legal limit in 2017 are a routine consumable, but given the low annual mileage it is worth confirming whether the tyres fitted at the point of sale are fresh or ageing, as old rubber deteriorates regardless of tread depth. Finally, the 2017 failure for a non-functioning offside front direction indicator suggests an electrical gremlin worth checking by cycling all indicators, hazard lights, and headlamps during the inspection to ensure no repeat of that simple but testable defect.
