2006 Vauxhall Signum 1.9L Diesel · KY06 NRE

The most recent MOT test for the Vauxhall Signum was conducted on 2016-11-01 and resulted in a passing grade, though it included several advisories that warrant careful consideration. Over the past decade, the vehicle’s MOT history demonstrates a pattern of recurring issues rather than a consistent improvement or stability. While earlier failures in 2014 and 2015 were primarily minor lighting faults and windscreen damage, the 2013 MOT revealed critical defects—specifically, rear tyre structural failures and a broken front coil spring—which indicate significant wear and potential underlying mechanical degradation. The fact that these issues were not addressed before the 2016 test suggests either inadequate maintenance or deferred repairs, raising concerns about the vehicle’s long-term structural integrity and suspension condition. The recorded mileage of 184,728 miles for a 2006 Signum represents a moderate annual usage rate of approximately 9,236 miles per year, which is within the expected range for a vehicle of this age and class. However, the absence of service records or a clear pattern of regular maintenance could imply either infrequent use or a history of neglect. Higher mileage typically accelerates wear on consumables like brakes, tyres, and suspension components, while prolonged idling or infrequent driving can lead to issues such as brake pad corrosion, standing corrosion in brake systems, and fluid degradation in hydraulic and cooling circuits. The advisories from 2016—particularly the tyre wear close to legal limits and brake pipe corrosion—highlight the need for vigilant monitoring, as these conditions may escalate with continued use. Given the MOT history, the prospective buyer should prioritise a thorough inspection of the suspension system, focusing on the front coil spring failure from 2013, which may have been partially repaired or overlooked. During a test drive, listen for unusual clunks or rattles from the suspension, especially when driving over bumps, as this could indicate worn or failing suspension bushes, lower arms, or struts. The brake system should be scrutinised for signs of uneven wear, binding calipers, or corrosion on brake discs and pads, with particular attention to the advisories of brake pipe corrosion. The tyres must be checked for sidewall perishing, which can occur even at moderate mileage due to age, and ensure they are not worn to the legal minimum. Additionally, verify the parking brake’s efficiency by observing its engagement and disengagement, as the 2015 advisory suggests potential issues with mechanical linkage or cable wear. For fluid systems, the coolant, brake fluid, and differential fluid should be checked for contamination or degradation, as these can degrade over time regardless of mileage. The vehicle’s battery health should be assessed, especially if it has been left standing for extended periods, as standing corrosion on terminals or a failing alternator can lead to electrical system failures. Finally, the windscreen should be inspected for any signs of repair quality or further damage, as the 2015 failure highlighted the importance of maintaining clear visibility. Given the vehicle’s age and the recurring advisories, it is advisable to obtain a pre-purchase inspection by a qualified mechanic to confirm the condition of the suspension, drivetrain, and structural components, ensuring no hidden defects have developed since the last MOT.
