2007 BMW 520 2.0L Diesel · YA07 AAF

A recurring theme of front suspension wear dominates the roadworthiness history of this 2007 BMW 520, with the track rod end ball joints appearing as advisories on the 2024 test and escalating into major defects causing failures on both the April 2025 and March 2026 examinations. The 2025 failure was particularly severe, recording excessive play at both nearside and offside front track rod ends, while the 2026 failure showed the offside joint had again deteriorated to the point of non-compliance despite a passing test issued the same day. This progression from slight play through to bilateral and then repeated failure suggests the front steering linkage has been a persistent weak point rather than an isolated incident. The current MOT status is a pass, dated 27 March 2026, but it should be noted that it was achieved on the same day as a failure, meaning rectification work was carried out and verified at the test station rather than independently inspected. Against an age of nineteen years, the recorded 189,563 miles equates to an average of approximately 9,977 miles annually, which sits broadly in line with typical usage for a vehicle of this vintage. The testing pattern shows annual examinations in 2024, 2025, and 2026, indicating the car has remained in regular use throughout the recorded period with no significant gaps that would suggest extended standing. Consistent annual mileage on a nearly two-decade-old executive saloon places ongoing demand on consumable components, and the advisory history bears this out with brake pad wear, shock absorber oil misting, and persistent oil leaks all surfacing within the available record. For a prospective buyer, the front suspension and steering assembly should be treated as the primary mechanical concern. The track rod end ball joints have now been flagged at three consecutive tests, with the severity progressing from slight play to complete failure, and any replacement carried out on the day of the 2026 test should be verified by physical inspection for new components and proper torque. On a test drive, listen for clonking or knocking noises from the front end over speed humps and uneven surfaces, pay close attention to any vagueness or delay in steering response, and check for uneven tyre wear across the front axle which would confirm the tracking geometry has been disturbed. The brake hoses flagged as slightly deteriorated on the offside front in 2026 are also worth pressing on physically to assess for cracking or perishing of the outer rubber, and the rear brake pads noted as wearing thin in 2025 will likely require attention imminently given the mileage covered since. The oil leak and front shock absorber misting advisories from 2024 and 2026 represent secondary but ongoing concerns. An oil leak classified as not excessive is consistent with age-related gasket and seal degradation on the E60 generation, but the buyer should inspect the engine bay and undertray for fresh oil accumulation, check the level on the dipstick, and be alert to any blue smoke from the exhaust on startup which would suggest the oil is tracking into the combustion chambers. Light oil misting on the nearside front shock absorber indicates the seal is beginning to fail rather than the unit being completely spent, but given the vehicle's age and mileage, budgeting for replacement of both front dampers in the near term would be prudent. A firm press on each front corner with the vehicle stationary should reveal any loss of damping force through uncontrolled bouncing, and any knocking from the top mounts under braking or cornering would indicate the strut assemblies are reaching the end of their service life.
