2004 BMW 545 4.4L Petrol · RG04 CYY

The latest MOT test for this BMW 545 occurred on 2024-10-18, resulting in a passing outcome with a single advisory—nearside non-obligatory mirror damage—which is a cosmetic issue and does not affect roadworthiness. Despite a previous failure in 2024-10-04, where major defects related to faulty rear position lamps and incorrect headlamp aim were recorded, the vehicle has since returned to a clean MOT history, suggesting either corrective action was taken or the issues were resolved before the subsequent tests. The recurring advisories from 2020—particularly the thin brake pads and oil leaks—were also addressed, with no further failures noted since then, indicating a general trend toward stability in maintenance. However, the presence of persistent wear advisories on brake pads and the oil leak history warrants continued vigilance, as these could escalate if left unchecked. The vehicle’s mileage of 115,781 miles at a recorded age of approximately 22 years represents a relatively low annual usage rate of around 5,263 miles per year, which is unusually low for a car of this age and model. Such low mileage often reflects prolonged periods of inactivity, potentially leading to issues such as standing corrosion on brake components, fluid degradation from stagnation, and wear from infrequent use of suspension and drivetrain systems. The absence of higher mileage accumulation suggests that while the vehicle may not have been subjected to heavy daily wear, it has likely experienced extended periods stationary, which can accelerate deterioration in consumables like brake pads, seals, and fluids. Buyers should be cautious about the implications of low usage, particularly regarding brake system corrosion and potential fluid degradation over time. Given the vehicle’s mileage and maintenance history, the prospective buyer should conduct a thorough physical inspection focusing on the brake system, suspension, and fluids. First, examine the brake pads and discs for signs of corrosion or binding, especially on the near and offside fronts where wear advisories were noted. Listen for any grinding noises when braking, which could indicate metal-to-metal contact from worn pads or warped discs. Additionally, check for uneven tyre wear patterns, as the offside rear tyre was recorded as worn close to the legal limit, suggesting potential alignment or suspension issues. Inspect the brake fluid level and condition, as standing fluid can degrade over time, leading to moisture contamination and reduced braking performance. The oil leak advisories should prompt a check for fluid under the vehicle, particularly around the valve cover, oil filter housing, and rear main seal area, while listening for any unusual engine noises or oil consumption patterns. For fluids and systems not directly related to the MOT advisories, the buyer should verify the condition of the coolant, transmission fluid, and differential oil, as these should be replaced according to BMW’s service schedule—typically every 60,000 to 100,000 miles or every 5 years, whichever comes first. Given the vehicle’s age, the 12V battery should be tested for voltage output and overall health, as prolonged inactivity can lead to sulphation or weak terminals. Finally, check the tyre sidewall for signs of cracking or perishing, which can compromise structural integrity and safety, especially if the vehicle has been stationary for extended periods. A test drive should include monitoring for suspension clunks or uneven ride quality, which may indicate worn suspension bushes or coil springs, and checking for any exhaust emissions issues, particularly if the vehicle has been stationary for long periods, as catalytic converter efficiency can degrade over time. If any of these checks reveal concerns, further diagnostic work may be necessary to address potential long-term mechanical risks.
