2014 BMW M4 3.0L Petrol · BT14 AAN

The latest MOT test for this 2014 BMW M4 was conducted on 2025-07-11 and resulted in a pass, though it included two persistent advisories that require attention. The advisories—an oil leak from the engine compartment, which is categorised as not excessive but still indicative of a developing issue, and the absence of the near-side front jacking point rubber mount—suggest a maintenance trend that has not significantly worsened but also does not reflect a fully resolved problem. The vehicle’s MOT history shows a pattern of stability from 2022 onwards, with no failures until the advisories appeared in 2024 and 2025, indicating that while the car has been maintained within legal standards, the recurring oil leak and jacking point issue warrant closer scrutiny to prevent escalation into a failure during the next test. The absence of any major defects in the preceding clean MOTs suggests that the current advisories are likely related to specific wear or design considerations rather than widespread mechanical failure. The recorded mileage of 94,647 miles for a vehicle aged 12 years represents a moderate annual usage rate of approximately 7,887 miles per annum, which is consistent with the expected wear profile for a high-performance BMW M4 in its class. This level of mileage does not necessarily indicate excessive driving, but it does imply that consumables such as brake pads, suspension components, and drivetrain fluids have been subjected to regular use, potentially leading to accelerated wear. The consistency of the mileage suggests that the vehicle has not been subjected to extreme conditions like heavy towing or prolonged idling, which could otherwise accelerate corrosion or fluid degradation. However, the absence of significant mileage gaps does not guarantee that the car has been driven optimally, and a thorough inspection should account for potential hidden wear from prolonged standing or infrequent use, such as brake disc corrosion or binding calipers. Given the recurring oil leak advisory and missing jacking point mount, the prospective buyer should prioritise a detailed mechanical inspection to confirm the source and severity of the oil leak. The oil leak from the engine compartment could stem from a failing oil seal, gasket, or a worn piston ring, all of which can lead to increased oil consumption and potential long-term engine damage if left unaddressed. Symptoms to watch for during a test drive include excessive smoke from the exhaust, particularly on cold starts, a noticeable oil smell in the cabin, or a rising oil pressure gauge reading. The missing jacking point rubber mount is a structural advisory that could compromise the vehicle’s stability if the jacking point is used for support, increasing the risk of damage to the subframe or suspension components. Inspect the jacking point itself for signs of wear or damage, and ensure that any alternative support methods are secure and compliant with BMW’s recommended practices. For the broader physical condition of the vehicle, the buyer should conduct a comprehensive inspection focusing on the following areas. Given the car’s age and mileage, the tyres should be checked for sidewall perishing, which can occur even at moderate mileages due to prolonged exposure to UV light and temperature fluctuations. The near-side rear tyre shows a near-side wear advisory from the last MOT, indicating potential misalignment or suspension issues that may have caused uneven tread wear. Inspect the suspension for signs of excessive play, clunking noises during cornering or over bumps, or uneven coil spring sag, which could signal worn suspension bushes or damaged control arms. The brakes should be examined for signs of corrosion on the discs, particularly on the near-side where standing conditions may have accelerated rust formation, and for any binding or excessive heat discolouration that could indicate a failing caliper or warped discs. Additionally, the battery should be tested for voltage output and corrosion on terminals, as BMWs of this age are prone to battery failure if not maintained, especially with the high electrical demands of the M4’s performance systems. Fluid levels should be checked for calendar-based degradation, particularly the engine oil, transmission fluid, and brake fluid, which should be replaced according to BMW’s recommended intervals, even if mileage is moderate. Finally, a visual inspection of the exhaust system for leaks, corrosion, or excessive wear is essential, as the M4’s performance exhaust can develop leaks or emissions-related issues over time, particularly if the vehicle has been driven at high RPMs.
