2017 BMW 320 2.0L Diesel · AF17 TYT

The most recent MOT test on the 2017 BMW 320 occurred on 2025-11-04 and resulted in a passing grade, though it included two advisories: an oil leak from the transmission area that was deemed not excessive, and a minor rear oil leak also not considered severe. The overall maintenance trend over the past five years is relatively stable, with no repeated failures and only a few advisories that have either resolved or remained consistent without escalation. The vehicle has not failed an MOT since 2022, suggesting that while some wear-related issues are present, they are either managed or within acceptable operational limits. The absence of dangerous failures and the lack of repeated critical defects indicate that the car remains roadworthy with only minor, manageable concerns that do not compromise safety. The vehicle’s recorded mileage of 93,567 miles at the time of this assessment represents a typical annual usage rate of approximately 10,396 miles per year, which aligns with the expected wear pattern for a nine-year-old BMW 320 in its class. This level of mileage is neither unusually high nor low for the age, though it does imply consistent use over the years, which can accelerate wear on consumables like brake pads, tyres, and fluid systems. The absence of significant mileage gaps suggests the car has been in regular service, potentially contributing to the observed maintenance stability. However, the presence of multiple advisories—particularly around tyre wear and brake pad condition—indicates that the vehicle has undergone some degree of operational stress, warranting closer attention to these components to prevent premature failure or safety risks. For the prospective buyer, the most critical areas to inspect are the front and rear tyres, given the repeated MOT advisories regarding tread depth and edge wear. The nearside and offside front tyres have been flagged as worn close to the legal limit, with the near-side outer tyre failing the MOT test in 2022 with a tread depth below 1.6mm. On a test drive, listen for uneven tyre wear patterns, which may indicate misalignment, poor suspension, or steering issues. Check for lateral cupping or directional wear, as these can signal alignment or camber problems. Additionally, visually inspect the tyres for signs of dry rot or sidewall cracking, which can compromise structural integrity, especially given the vehicle’s age. The brake pads, particularly the rear set, have been noted as wearing thin in multiple MOTs, suggesting they may require replacement soon. Listen for a grinding noise when applying the brakes, which could indicate metal-to-metal contact if the pads are critically worn. Inspect the brake discs for scoring, warping, or corrosion, and check for binding calipers that may restrict disc movement. Beyond tyres and brakes, the oil leaks from the transmission area and rear of the vehicle warrant further investigation. The oil leaks—both front and rear—are not excessive but could indicate failing seals, gaskets, or wear in the transmission or drivetrain components. On a test drive, pay attention to unusual fluid smells, particularly near the transmission or rear axle, and check for visible oil stains under the vehicle. If the leaks are persistent, they may lead to increased oil consumption or contamination of the drivetrain fluids, which can degrade performance and longevity. Given the calendar age of the vehicle, it is also prudent to verify the condition of the 12V battery, as BMWs of this era can suffer from corrosion in the battery terminals or internal degradation over time. Check the battery terminals for signs of oxidation or corrosion, and ensure the battery holds a charge when tested. Additionally, the vehicle’s fluids—particularly the engine oil, transmission fluid, and coolant—should be checked for degradation. Engine oil should be replaced every 60,000–100,000 miles or every two years, whichever comes first, to prevent sludge buildup and internal wear. The transmission fluid should be serviced annually or every 15,000–20,000 miles to maintain smooth operation and prevent premature failure. Lastly, inspect the exhaust system for corrosion or structural integrity, as BMWs can be prone to rust in the tailpipe and catalytic converter areas, especially if the vehicle has been exposed to wet conditions.
