2009 Volkswagen Polo 1.2L Petrol · B5 OLL

A clear pattern of corrosion-related advisories across the suspension and exhaust, combined with a serious brake imbalance failure and a worn suspension arm, defines the mechanical story of this 2009 Volkswagen Polo. The most recent test on 2026-03-17 returned a pass, but only alongside advisories for a heavily corroded rear exhaust silencer with peeling outer skin and a deteriorating rear registration plate. Looking at the broader trajectory, the 2024 test already flagged corrosion on both front lower suspension arms and a corroded rear silencer, while the early 2025 test escalated concerns dramatically with a dangerous front brake imbalance of more than 50 percent across axle one, below-requirement parking brake efficiency, and advisories for corroded front inner suspension arms and rear coil spring mountings. A subsequent failed attempt on 2025-04-03 identified an excessively worn rear bush on the offside front suspension arm, before the car finally passed on 2025-04-04 with no recorded defects. This sequence indicates that significant mechanical work was carried out between February and April 2025, and the roadworthiness picture is one of a car that has needed active intervention to remain compliant, rather than one passing through tests with minimal concern. Recorded mileage of 48,595 miles over roughly seventeen years equates to an annual accumulation of around 2,850 miles, which is notably low for the vehicle's age and typical Polo usage patterns. This restrained mileage profile will have limited wear on major drivetrain and braking components in absolute terms, but it also raises the usual caveats associated with low-mileage vehicles, particularly extended periods of standing or only short journeys, which can accelerate corrosion on underbody components and allow brake discs to corrode on the surface. The advisories on the rear coil spring mounting and inner suspension arms are consistent with age-related underbody oxidation rather than high-mileage mechanical wear, and the brake imbalance failure may well reflect seized or binding mechanisms from infrequent use rather than worn friction material. For a prospective buyer, the priority inspection points are the front suspension components, given the recorded excessive wear on the offside front arm rear bush and the corrosion advisories on both front lower arms and inner arms. On a test drive, listen for clonking or knocking noises from the front end over speed bumps and rough roads, and feel for vagueness or delay in steering response that could indicate worn bushings or play in the suspension joints. The brake system warrants particular attention: check for pulling to one side under moderate braking, any grinding or scraping noises, and a spongy or excessively long pedal travel. Inspect the parking brake hold on an incline to confirm adequate efficiency, as this was below requirement in February 2025. Also examine the rear silencer visually for perforation or rattling on start-up, and check both rear tyres closely for uneven wear or sidewall deterioration consistent with ageing rubber. Finally, given the underbody corrosion pattern, a physical inspection on a ramp is strongly advisable before purchase. Pay particular attention to the front subframe mounting points, rear coil spring seats, and brake pipes for any surface rust or corrosion scaling, as these are typical corrosion hotspots on a Polo of this generation. Verify that the recent suspension and brake rectification work has been completed to a satisfactory standard by requesting invoices, and confirm that the tyres are of recent manufacture rather than aged stock. With the corrosion advisories already documented across consecutive tests, ongoing annual inspection of these areas will be essential to keep the vehicle in roadworthy condition.
