2015 Vauxhall Mokka 1.4L Petrol · SW15 SJO

The latest MOT test in June 2026 resulted in a pass after an initial failure due to a misaligned nearside headlamp, which was promptly rectified. However, the test revealed a cluster of advisories that signal emerging concerns, particularly with the exhaust system, brake pipes, and the offside rear wheel bearing. The trend over the past year shows a deterioration in condition, with no advisories in 2024 and 2023 but a growing list in 2025 and 2026, suggesting that some components are now reaching the end of their serviceable life. The stability of earlier years has given way to a worsening pattern, and these issues will require close attention. At 11 years old with just over 56,000 miles, this Mokka has covered an average of around 5,100 miles annually, which is relatively low for its age. Such usage implies the vehicle may have spent extended periods stationary, which can lead to its own set of problems, including seized or binding components, degraded seals, and corrosion. The low mileage does reduce wear on moving parts like the engine and transmission, but it increases the risk of age-related deterioration in rubber, plastic, and metal components that degrade over time regardless of use. The advisories from the 2026 test demand immediate scrutiny. The minor exhaust leak at the rear silencer may manifest as a faint hissing or ticking noise from the rear of the vehicle, particularly when cold, and could worsen if left unaddressed, potentially leading to increased emissions or further damage. The corroded brake pipes, especially where swollen under the plastic coating, are a serious safety concern, as they may fail under pressure, leading to brake fluid loss and reduced braking efficiency. Inspect the pipes thoroughly for rust, pitting, or bulging, and check for any signs of fluid leakage around the joints. The offside rear wheel bearing, noted as slightly noisy and with slight play, will likely produce a low-frequency rumbling or growling noise that increases with speed. If left unattended, this can lead to complete failure, causing the wheel to seize or detach. During a test drive, listen for these symptoms and check for excessive movement when the wheel is rocked sideways at the top and bottom. Given the vehicle’s age and low mileage, also prioritise checks for standing-related issues. Inspect the tyres for sidewall cracking or perishing, as rubber degrades over time even with minimal use. Test the 12V battery health, as prolonged inactivity can lead to sulphation and reduced capacity. Examine the brake discs for surface corrosion or uneven wear, which can cause juddering under braking, and ensure the calipers are not binding. Verify the condition of all fluid reservoirs and hoses, as seals and gaskets can harden and leak with age. Finally, review the service history to confirm that time-based maintenance, such as coolant and brake fluid changes, has been carried out, as these are critical regardless of mileage.
