2010 Mercedes-Benz A-Class 1.5L Petrol · 123 ADL

The most recent DVSA test on 4 November 2025 recorded a failure for a major fault – the off‑side side‑repeat indicator was inoperative – and a series of advisories concerning brake‑hose deterioration, corroded brake pipes, a near‑side rear nail in the tyre and excessive hand‑brake travel. Although the vehicle also received a “passed” result on the same date, the presence of a major defect means the MOT was ultimately rejected. Over the preceding five‑year period the pattern has been one of accumulating advisories, with occasional failures for unrelated items such as washer‑fluid supply, indicating that the overall maintenance trajectory is deteriorating rather than stabilising. At 73,046 mi the A‑Class has covered an average of roughly 4,600 mi per annum, which is considerably below the typical UK usage of 10‑12 000 mi per year for a vehicle of this age. The low mileage suggests periods of limited use or prolonged storage, which can be as detrimental as high mileage if the car has been stationary for extended intervals. Inactivity tends to accelerate rubber and polymer ageing, promote internal corrosion, and allow brake components to seize, while also masking wear that would otherwise be evident under regular operation. Prospective buyers should give particular attention to the brake system. The repeated advisories about cracked and perished brake hoses on both front and rear circuits imply that the hoses are approaching the end of their service life and should be replaced as a matter of safety. Corroded brake pipes, especially those covered in grease or other material, are a sign of rust penetration that can lead to fluid leakage, reduced braking efficiency and uneven pedal feel; a visual inspection of the pipe interiors and a pressure test are advisable. The hand‑brake’s excessive travel points to possible cable stretch or caliper binding – the hand‑brake should be tested for firm, consistent engagement and, if necessary, the cable adjusted or replaced. The off‑side side‑repeat light failure is an electronic fault that, while not affecting roadworthiness, should be rectified to avoid future MOT rejections; a diagnostic scan can confirm whether the bulb, wiring or control module is at fault. Finally, the near‑side rear tyre nail must be removed and the tyre inspected for internal damage; given the history of tyre wear warnings on the off‑side front, a full tyre tread depth and sidewall inspection is essential, looking for age‑related cracking or perishing of the rubber compound. Beyond the brake and tyre concerns, the car’s age warrants a thorough check of components that degrade with time. Verify the condition of the 12 V battery, including charge hold and electrolyte level, as a 16‑year‑old unit is likely nearing the end of its service life. Inspect all fluid reservoirs – engine oil, coolant, transmission and power‑steering – for signs of discoloration, sediment or loss of volume, and consider a complete fluid change if the last service date is unclear. Examine the suspension bushings, coil springs and shock absorbers for any creaking, clunking or uneven ride quality, which can develop from prolonged standing. Look for corrosion on chassis mounting points, exhaust brackets and under‑body panels, especially around the brake‑pipe areas that have already shown rust. A comprehensive test drive listening for brake shudder, steering pull or abnormal vibrations will help confirm that any latent wear has not progressed to a critical failure before committing to purchase.
