2005 Mercedes C 1.8L Petrol · SC05 PFU

This vehicle presents a worsening maintenance trend, culminating in a failed test just under three years ago on 17 July 2023 at 141,817 miles. While the car ultimately passed that day, the tester first rejected it for an inoperative engine management light, indicating a deliberate or negligent attempt to pass the car with an active engine fault. Alongside this major failure, the record shows a persistent neglect of underlying chassis and braking issues that have been flagged repeatedly since 2021. The overall trajectory demonstrates a clear decline in standard upkeep. Mileage accumulation aligns with typical usage for a twenty-one-year-old Mercedes, averaging roughly 6,750 miles annually across its life. The recorded distances show a steady and consistent pattern, with no sudden spikes or unexplained gaps that might suggest clocking or prolonged periods standing idle. Between July 2022 and July 2023, the car covered approximately 6,283 miles, reflecting normal driving conditions rather than abnormal wear from excessive short trips or heavy load use. A buyer must prioritize a thorough underbody inspection focusing on the rear suspension and braking system. Both rear coil springs have carried a corrosion advisory continuously since July 2021 at 124,995 miles, meaning they have deteriorated over 16,000 miles and three subsequent tests without replacement. This persistent surface rust risks structural fracture. The nearside rear brake pipe was flagged as corroded and obscured by grease in the July 2023 test, demanding immediate physical verification to ensure hydraulic integrity has not been compromised. The front suspension and engine management systems require equal scrutiny. The July 2022 test at 135,533 miles failed the car for severely deteriorated anti-roll bar linkage dust covers on both sides, alongside front tyres worn well past legal limits on the outer edges, which suggests a history of skipped basic upkeep and poor steering geometry. By July 2023, the tester noted slight play in the offside front anti-roll bar ball joint, confirming ongoing component degradation in that area. The engine management light malfunction that caused the initial July 2023 failure must be interrogated diagnostically to ensure the fault was genuinely rectified rather than merely cleared to secure a pass certificate.
