2004 BMW 3 Series 2.5L Petrol · R77 RCV

The most recent MOT test on 22 May 2025 confirms the vehicle passed without defects at 144,187 miles, though the preceding test on 20 May 2024—just one day earlier—was a failure at the same mileage. This suggests a last-minute rectification of issues, as the 2023 tests also show a failed and passed result within days of each other at 117,285 and 117,315 miles respectively. While the vehicle has cleared its most recent inspection, the pattern of repeated near-term retests implies either rushed repairs or a history of minor but recurring faults that were just barely addressed before the test window closed. The absence of defects in the latest pass does not negate the need for thorough scrutiny of components that may have been previously problematic, particularly those related to braking, suspension, or emissions systems. The mileage progression reveals an average of approximately 6,550 miles per year, which is typical for a vehicle of this age. The gap between tests is consistent at around 11 months, with no extended periods of inactivity or rapid mileage accumulation. The 2023 and 2024 tests occurred within a single month, suggesting either a deliberate scheduling strategy or a response to repeated failures. There is no evidence of prolonged neglect, but the repeated retests at similar mileages warrant closer examination of wear items that might have been overlooked or inadequately serviced. Given the history, a buyer should prioritise an inspection of the braking system, particularly the rear brakes, which were likely the cause of the 2024 failure. Binding calipers, unevenly worn brake discs, or degraded rear brake linings are common issues in this model at this mileage. The suspension should also be assessed for worn or leaking bushes, corroded coil springs, or excessive play in the strut mounts, as these components often fail intermittently and may have been temporarily fixed before the MOT. Corrosion in wheel arches, subframes, or exhaust components should be checked, especially if the vehicle has seen wet or salted roads. Finally, the emissions system—particularly the catalytic converter—should be tested for efficiency, as repeated failures in this area are not uncommon in older BMWs. A pre-purchase diagnostic scan for stored fault codes would provide further clarity on any unresolved mechanical concerns.
