2006 Volkswagen Touran 2.0L Diesel · BN56 AAU

The most recent MOT, dated 18 September 2024, resulted in a failure. The reasons were a dangerous reduction in parking‑brake efficiency, major split CV‑boots on both front drive‑shafts, an advisory oil‑leak and a corroded near‑side front coil spring. Over the last five years the pattern has moved from a single suspension‑arm failure in 2021 to an increasing number of wear‑related advisories and now to outright failures, indicating a clear deterioration rather than a stabilising maintenance trend. At 135,849 miles the Touran averages roughly 6,800 miles per year, which is typical for a vehicle of its age. The mileage does not suggest any period of extreme abuse, but it also does not reflect very low‑usage, long‑term storage. Consequently the wear on consumables such as brakes, tyres, suspension bushings and CV joints is consistent with a vehicle that has been driven regularly rather than intermittently, and the accumulated kilometres will have contributed to the progressive thinning of pads, boot degradation and bearing play noted in the MOT records. A prospective buyer should give particular attention to the front CV‑boots: inspect the boots for cracks, splits or grease leakage and feel for any abnormal whine or vibration when accelerating and turning, which would indicate joint contamination. The parking‑brake cable and adjuster must be examined for corrosion, frayed housing and proper tension; a functional test should confirm the brake holds the vehicle on a steep incline without slipping. The near‑side front coil spring, noted as corroded, should be checked for loss of stiffness or broken coils that could affect ride height and handling. Front suspension ball‑joints and lower‑arm bushes, previously recorded as excessively worn, should be probed for play and any clunking over bumps, as failure here can lead to steering imprecision. Rear wheel bearings, flagged with slight play, ought to be spun for smoothness and listened to for grinding, while the rear shock absorbers should be examined for oil seepage and tested for bounce to ensure they are still damping effectively. Brake pads on all corners have been reported as thin; the buyer should expect a pad replacement soon and verify that the discs are free from scoring or excessive rust. Tyre tread depths must be measured across the entire width; the history of edge‑wear suggests possible mis‑alignment or uneven loading that should be corrected before new tyres are fitted. Given the vehicle’s two‑decade age, additional calendar‑based checks are prudent. Inspect the under‑carriage and wheel arches for rust, especially around the suspension mounting points and exhaust system. Verify the condition of the 12‑volt battery, checking terminal corrosion and performing a load test, as prolonged standing can reduce capacity. Examine all fluid levels and consider a full change of engine oil, coolant, brake fluid and power‑steering fluid, since fluid degradation occurs with time regardless of mileage. Finally, confirm that the service book contains regular oil‑change stamps and that any major component replacements, such as CV‑boot refurbishments or suspension work, are documented, providing confidence that the vehicle has been maintained in line with manufacturer recommendations.
