2015 Mercedes-Benz GL 3.0L Diesel · LT65 YEB

The vehicle is currently roadworthy, but the maintenance history reveals a reactive approach to repairs rather than preventative care. The most recent test in December 2025 at 113,733 miles showed a pass only after a failure the previous day. This failure identified a worn offside front suspension arm ball joint, a missing nearside rear wheel fixing, and a deteriorated offside front CV boot. While the vehicle passed, the recurring nature of these faults suggests the owner only addresses mechanical issues once they threaten an MOT certificate. The mileage pattern is consistent with typical usage for its age, averaging approximately 10,300 miles per year. Records show a steady progression from 86,812 miles in December 2023 to 100,277 miles in December 2024, and reaching 113,733 miles by December 2025. This regular accumulation indicates the vehicle is used consistently rather than sitting stationary for long periods, which is generally better for rubber components and brake seals, despite the wear seen on a heavy SUV like this GL. A buyer must scrutinise the drivetrain specifically, as CV boots have appeared as a point of failure in three consecutive years across 2023, 2024, and 2025. The persistent deterioration of these boots can lead to grease loss and grit ingress, which eventually results in expensive drive shaft replacements. Furthermore, the 2024 failure regarding the supplementary restraint system warning lamp indicates a past airbag or sensor fault that should be verified as resolved to ensure safety systems are fully functional. The suspension and brakes also require close attention. Given the worn ball joint noted in late 2025 and the thin brake discs flagged back in 2023, a physical inspection should check for play in the steering geometry and uneven wear on the rotors. The missing wheel fixing noted in the 2025 test also highlights a lapse in basic safety checks, necessitating that the buyer verifies all wheel bolts are properly torqued to specification before purchase.
