2013 Mercedes-Benz A-Class 1.8L Diesel · L22 RAD

The most recent MOT on 13 July 2026 was passed, but it carried three advisories of note: both front brake pipes were reported as corroded and covered in grease, and all four tyres were flagged as slightly damaged or perishing. Over the past six years the record shows a consistent pattern of front brake disc wear and scoring, progressive thinning of front brake pads, and a growing number of tyre condition warnings. The appearance of corrosion on the brake pipe assemblies in the latest test marks a step up in severity, indicating that the overall maintenance trend is moving from a stable but wear‑related state to one that now includes potential safety‑critical defects. At 47,354 mi the car averages roughly 3,600 mi per annum, which is well below the typical UK usage for a 13‑year‑old vehicle. Such low annual mileage often points to periods of infrequent use or prolonged storage, a factor that can accelerate age‑related deterioration such as rubber perishing, battery sulphation, and corrosion on hidden components. There is no evidence of any sudden mileage spikes that would suggest aggressive short‑term use, but the low utilisation combined with the age of the vehicle means that many wear items are likely to be driven more by calendar life than by distance. A prospective buyer should give the brake system the highest priority. Inspect both front brake pipes for rust penetration, pitting or any signs of fluid leakage; a corroded pipe can compromise hydraulic pressure and produce a spongy pedal feel. Examine the front discs for depth and surface condition – pitting and scoring, even if not yet weakened, can lead to reduced braking efficiency and vibration at higher speeds. Verify that the front pads have sufficient remaining material beyond the wear indicator and that the calipers move freely without binding. On a test drive listen for any squeal, groan or pulsation when applying the brakes, and feel for any increase in pedal travel that could signal fluid loss or pipe leakage. Equally important is a thorough tyre and ancillary check. All four tyres have been flagged for perishing; look for sidewall cracks, dry rot, or bulges, and measure tread depth to ensure it exceeds the legal 1.6 mm minimum and is even across the tyre. Because the car has likely spent long periods stationary, inspect the battery for reduced cranking power and check the electrolyte level if it is a conventional lead‑acid type. Examine the suspension bushes, ball joints and shock absorbers for signs of dry rotting or excessive play, and verify that the under‑trays and engine covers that were fitted are not trapping moisture against the chassis, which could promote rust. Finally, confirm that the brake fluid, coolant and engine oil have been changed in line with the manufacturer’s time‑based intervals, as fluids degrade with age even when mileage is low. Addressing these items before purchase will give a clear picture of the car’s remaining service life and any imminent out‑of‑pocket costs.
