2016 BMW 120 2.0L Diesel · CJ16 AAX

The latest MOT test on 2025-10-15 reveals a stable but concerning maintenance profile, with the vehicle passing all other tests since 2022. While the absence of failures in the preceding three years suggests consistent upkeep, the presence of multiple advisories—particularly the repeated wear and pitting on both front and rear brake discs—indicates ongoing mechanical attention is required. The rear tyre edge wear and oil damp in the rear differential cover further highlight areas of wear progression that demand proactive monitoring, as they may signal deeper issues such as misalignment, excessive load distribution, or potential drivetrain component fatigue. The recorded mileage of 78,513 miles over approximately ten years translates to roughly 7,851 miles annually, which is within the expected range for a vehicle of this age and class, assuming moderate to heavy usage. However, the lack of significant mileage spikes between MOT tests suggests either deliberate low-mileage operation or extended periods of inactivity, which can exacerbate certain wear patterns. Standing for prolonged durations may lead to brake system corrosion, particularly on the rear discs and calipers, as moisture and road salt can accelerate rust formation, while the rear tyre’s edge wear could be exacerbated by uneven load distribution or misaligned wheels. Conversely, if the vehicle has accumulated miles more rapidly in recent years, this would warrant closer inspection of suspension components, drivetrain seals, and fluid integrity, as higher mileage typically accelerates wear on consumables like brake pads, suspension bushes, and exhaust components. To proceed with a thorough inspection, the prospective buyer should commence with a visual and functional assessment of the braking system. The advisories on the brake discs—particularly the lipping and pitting—suggest that the pads have been worn down to the metal, which may have already caused excessive heat generation, warping, or uneven wear. During a test drive, listen for any grinding noises when applying the brakes, especially on the rear, as this could indicate metal-to-metal contact between the discs and pads. Additionally, check for any brake pedal pulsation or vibration, which may signal warped discs or binding calipers. Inspect the rear wheels for signs of uneven tyre wear, which could correlate with misaligned wheels or suspension issues, and verify that the rear tyre’s tread depth is not approaching the legal minimum, as the edge wear suggests potential underinflation or excessive load. Beyond the brakes, focus on the rear differential cover for signs of oil leakage or excessive dampness, which may indicate a failing seal or worn bearings. The oil dampness recorded in the MOT could also imply internal drivetrain component wear, such as the differential gears or side gears, which may require fluid replacement or inspection. For the suspension, examine the rear for any signs of sagging coil springs, damaged suspension bushes, or excessive play in the control arms, as these can contribute to the tyre edge wear and uneven loading. Finally, address the tyre sidewall condition, as the age of the vehicle—approaching its typical service life—may have led to cracks or perishing from exposure to UV radiation and temperature fluctuations. Check the 12V battery for signs of corrosion on terminals, a failing voltage regulator, or excessive internal resistance, as standing vehicles are prone to battery drain. Schedule a fluid service, particularly for the brake fluid, transmission fluid, and coolant, as these fluids degrade over time, even with minimal usage, and should be replaced at the manufacturer’s recommended intervals to maintain performance and prevent corrosion.
