2009 Volkswagen Tiguan 2.0L Diesel · FN59 LVM

The most recent MOT, dated 26 June 2024, was passed but carried three advisories – a corroded central exhaust mounting clamp, corrosion on the rear lower suspension arm and slight play in the rear bush of the off‑side front lower suspension arm. Earlier in the same week the vehicle failed due to a fractured off‑side rear coil spring and a non‑functioning engine MIL indicator, while previous years show a mixture of minor and major failures, notably coil‑spring fractures in 2020 and tyre damage in 2021. The pattern indicates that the vehicle has required intermittent corrective work, particularly to the suspension and exhaust mounting, but the most recent pass suggests those immediate faults have been remedied; however, the persistence of advisories points to a maintenance trend that is stabilising rather than improving. At 96,938 mi for a 2009 model the annual average mileage works out at roughly 5,700 mi per year, which is well below the typical UK usage of 8‑12 000 mi per annum. Such low mileage often reflects periods of limited use or prolonged storage, which can be as detrimental as high mileage in terms of rubber perishing, battery sulphation and corrosion of metal components. The modest mileage means that wear items such as clutch, gearbox and engine internals are likely to be in relatively good condition, but the vehicle’s age means that time‑related degradation must be considered, especially for seals, hoses and the suspension bushings that have already shown corrosion. When you inspect the vehicle, give particular attention to the exhaust system – the central clamp was flagged on three occasions and is now corroded; any rattling or sulphur‑smelling exhaust on acceleration could indicate a loose or cracked clamp. The rear lower suspension arm, noted as corroded but not yet weakened, should be examined for rust penetration and any play when the wheel is rocked; a clunk or uneven ride may signal that the arm is approaching structural failure. The off‑side front lower arm ball joint has slight rear‑bush play, so listen for knocking over bumps and check for uneven tyre wear which would betray a compromised joint. Both the off‑side rear and front coil springs have previously fractured, so a visual inspection of all coil springs for cracks, corrosion or loss of tension is essential, and a bounce test of each wheel should be performed to detect any soft or collapsed springs. Verify that the engine MIL indicator illuminates correctly on the dash; a persistent fault could mask underlying sensor or emission issues that may affect future MOTs. Given the vehicle’s age and low mileage, also examine the tyre sidewalls for cracking, perishing or exposed cords, as several advisories have highlighted tyre damage in the past. Check the condition of the battery – a 17‑year‑old unit may suffer from reduced cranking power and may need a load test. Inspect brake discs for surface rust, scoring or uneven thickness, and ensure the calipers move freely without binding, as long periods of standing can cause corrosion of the pistons. Finally, confirm that all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – have been changed within the recommended calendar intervals, and that the service book contains stamps for these time‑based services; any missed fluid changes could lead to seal deterioration or corrosion in the drivetrain.
