2011 BMW 520 2.0L Diesel · YP11 WYC

The most recent MOT inspection on 29 July 2025 resulted in a pass, but the vehicle's maintenance trend shows a concerning pattern of recurring advisories. While the car has successfully passed its tests since 2021, there is a persistent and worsening trend regarding oil leaks and tyre degradation. The presence of an oil leak advisory in three consecutive tests since March 2023 indicates a chronic issue that has not been rectified. Although currently described as not excessive, this suggests a slow seepage from a gasket or seal that will eventually require more intensive mechanical intervention to prevent significant fluid loss or damage to other engine components. With approximately 131,695 miles covered over 15 years, the vehicle has averaged roughly 8,780 miles per year. This represents typical, moderate usage for a premium executive saloon of this age. The mileage is consistent enough to suggest the vehicle has not been subject to extreme long-term standing, which helps mitigate some risks of seized components or excessive brake disc corrosion. However, the mileage is high enough that wear on consumable items such as suspension bushes, drive belts, and cooling system hoses should be considered part of the standard maintenance profile for a vehicle of this era and distance travelled. A prospective buyer must pay close attention to the recurring oil leak advisory. During a test drive, you should monitor for any burning smells, particularly after the engine has reached operating temperature, which could indicate oil dripping onto the exhaust manifold. Under the bonnet, look for oily residue around the valve cover gasket, oil filter housing, or sump. Furthermore, the history of tyre advisories, including recent notes regarding a nail in the offside rear tyre and previous issues with uneven wear and perishing, suggests that the vehicle's wheel alignment or suspension geometry may be compromised. You should inspect the tyres for uneven tread wear on the inner or outer edges, which can indicate worn control arm bushes or incorrect toe settings, and check the sidewalls for any signs of cracking or perishing. Given the age and the specific history of this BMW, a thorough inspection of the suspension system is essential. The 2021 failure due to fractured front coil springs demonstrates that the suspension components are reaching the end of their service life. Listen for any metallic clunks or knocks when driving over speed bumps or uneven road surfaces, as this could indicate failing dampers or worn suspension bushings. Additionally, because the vehicle has seen consistent but moderate use, you should verify the service history to ensure that fluid changes, such as engine oil, coolant, and brake fluid, have been performed on a calendar basis rather than solely based on mileage, as chemical degradation occurs regardless of distance travelled.
