2013 BMW 7 Series 3.0L Diesel · LL13 AEZ

A thirteen year old BMW 7 Series with double fractured front coil springs recorded as major defects at the most recent test in November 2025 is the dominant mechanical story here, and it is one that warrants serious attention from any prospective buyer. A vehicle passing its MOT just seven days after a failure on both front coil springs is not unusual, as the springs would have been replaced in the intervening period, but it does flag that the suspension has been under considerable stress. The 2023 test also recorded a cut nearside front tyre deep enough to reach the ply or cords, classified as a major failure, alongside an advisory for both rear tyres being worn close to the legal limit and worn on the edge. Combined with the 2020 advisories for both front lower suspension arm pins or bushes showing wear, the recorded picture points towards a chassis and undercarriage that has absorbed significant mileage, with components now reaching the point of replacement rather than being merely monitored. Mileage of 102,816 against a 2013 registration represents an average annual accumulation of approximately 7,900 miles, which is broadly consistent with a vehicle of this age and class. There are no extended gaps in the MOT record that would suggest a prolonged period off the road, and testing has occurred consistently on an annual basis since at least 2020, giving a reliable chronological picture of the cars roadworthiness over the last six years. The relatively even distribution of tests suggests continuous use, which on a 7 Series of this vintage typically exposes the air suspension system, electronic dampers, and complex multi-link front and rear axles to sustained wear. The fact that the front coil springs fractured simultaneously is consistent with a vehicle that has covered meaningful mileage rather than one that has been stored or lightly used. From a buyer perspective, the immediate priority is confirming the quality and provenance of the replacement front coil springs, as both sides failed together, and inspecting the rest of the suspension for any signs of sagging, clonking, or uneven ride height. On a test drive, listen carefully for any knocking or creaking from the front end over speed humps and uneven road surfaces, as the lower arm bushes which were flagged as worn in 2020 may have deteriorated further in the intervening five years. Pay particular attention to the steering for any vagueness, vibration, or pulling to one side, which could indicate worn front suspension geometry or a perished coil spring on the opposite side that has not yet fractured completely. The rear tyres being flagged as edge worn in 2023 also suggests potential tracking or geometry issues that should be investigated, even though no tracking defect was explicitly recorded. Given the size, weight, and complexity of a BMW 7 Series, the brake system and any underbody corrosion should also be carefully examined, as the 2020 test recorded rear brake pads as wearing thin and the vehicle has covered further mileage since. On a test drive, feel for any judder through the brake pedal, pulling to one side under heavy braking, or any binding from the calipers after release, all of which would be consistent with worn discs or seized calipers. Inspect the underside of the vehicle on a ramp for any surface corrosion on subframes, brake pipes, and suspension components, as thirteen year old BMW chassis of this era are known to suffer from rust around the rear suspension mounting points and underbody bracing. Finally, verify that the tyres currently fitted are in good condition and correctly sized, as the 2023 advisory for edge wear and a major failure for a cut tyre both indicate that previous replacements may not have been optimal, and any uneven wear on the current set should be discussed with the seller before purchase.
