2009 Volkswagen Polo 1.4L Petrol · AP09 JCV

The Polo passed its most recent MOT on 14 November 2025, although a single advisory was issued for a minor exhaust gas leak from the exhaust system, which is the same defect noted at the preceding failed test. The broader MOT history over the past four years shows a clear pattern of recurring issues concentrated around the exhaust emissions, the rear braking system, and tyre condition. The 2024 test saw major failures for insufficient brake lever reserve travel, an excessively binding offside rear service brake, and elevated exhaust carbon monoxide at idle, while the 2025 failure added lambda reading and post-fast-idle CO exceedances to the list. The trend cannot reasonably be described as stable; the emissions and braking concerns have either persisted or reappeared in successive tests, and although the most recent outcome was a pass, the underlying mechanical causes were addressed only days before that pass, meaning the vehicle has effectively been failing on these areas regularly. The recorded mileage of 101,247 against an approximate vehicle age of seventeen years equates to an annual usage of just under 6,000 miles, which is considerably below average for a car of this type and age. This pattern typically reflects either genuinely light motoring or extended periods of standing, possibly combined with intermittent use. Either scenario carries distinct mechanical implications: low-mileage cars frequently suffer from time-related degradation rather than distance wear, particularly in areas such as brake calipers seizing, brake disc corrosion, suspension bushes perishing, and 12-volt battery deterioration. The evidence in the MOT record supports this, with multiple advisories over the years for brake binding on both front and rear calipers and pitted front brake discs, all classic symptoms of a vehicle that has spent considerable time stationary between journeys. Given the recurring advisories and failures, a prospective buyer should pay particular attention to the braking system on any test drive. The offside rear caliper has been flagged for binding or excessive binding in four consecutive tests, so the car should be driven slowly from cold with the windows down to listen for any dragging or rubbing sounds from the rear wheels, and the wheel should be spun by hand after a short drive to confirm it rotates freely without excessive resistance. Any pulling to one side under braking, or a brake pedal that feels spongy or requires excessive travel, would indicate that the binding has caused uneven pad wear or, in the worst case, hydraulic issues from a seized caliper. The front discs have been noted as pitted and scored since 2021, so sharp vibration through the steering wheel under firm braking would suggest the discs have worn beyond their service limit and need replacement. The exhaust system should be inspected on a cold start for any audible ticking or hissing from joints, particularly around the manifold and front pipe, and a hand placed near the tailpipe during idle will reveal any stray gas leakage contributing to the recurring emissions failures. Tyre condition warrants close inspection as the offside rear tyre has been flagged for perishing and cracking in three of the last four tests, which is highly characteristic of age-related rubber degradation rather than wear. The tread may appear adequate but the sidewalls and tread grooves should be examined for fine cracks, especially on the inside shoulder which is hardest to see; aged tyres of this nature can fail suddenly under load even when tread depth remains legal. Beyond the MOT-recorded items, the low annual mileage and seventeen-year age demand attention to time-served components that do not appear on the test: the 12-volt battery is very likely due for replacement and should be load-tested, all fluid services should be verified by service history (coolant, brake fluid, and gearbox oil all degrade by calendar age), the timing belt and water pump replacement interval must be confirmed as these are critical on the older Polo petrol engines, and the underbody should be examined for corrosion around the suspension turrets, subframe, and brake lines. Finally, the exhaust lambda and CO exceedances suggest the engine management system or catalytic converter may be drifting out of specification, so a diagnostic code read before purchase would be prudent to rule out any underlying sensor or catalyst deterioration.
