2015 Mercedes-Benz GLA 2.1L Diesel · KT15 OJB

Corrosion on the rear coil springs and recurring steering and suspension component failures define the mechanical profile of this vehicle, which most recently passed its MOT on 12 December 2025. The inspection history shows a trend of progressive wear in the suspension and steering systems, moving from a failed anti-roll bar linkage in 2022 to a significant brake disc wear failure in early 2024, and most recently a major failure regarding excessive play in the nearside front track rod end ball joint in late 2025. While the vehicle passed the subsequent test, the persistent advisories regarding corrosion on both the nearside and offside rear coil springs indicate an ongoing issue with component degradation that has been noted across multiple consecutive tests since January 2025. The vehicle has covered 135,773 miles over its eleven-year lifespan, representing an average annual accumulation of approximately 12,343 miles. This usage pattern is relatively high for a vehicle of this age, suggesting consistent road use rather than long periods of stationary storage. From a mechanical standpoint, this higher mileage profile increases the likelihood of accelerated wear on consumable components and structural elements, which is reflected in the recorded failures of braking surfaces and steering linkages. The steady mileage accumulation means that components subject to mechanical fatigue, such as suspension bushes, dampers, and drivetrain mounts, are likely approaching the end of their typical service life. A prospective buyer should pay close attention to the condition of the rear suspension during a test drive. Given the repeated advisories for corroded coil springs, listen for any metallic clunking or springing noises when traversing uneven surfaces or speed bumps, as significant corrosion can lead to sudden component failure. Furthermore, because the vehicle has recently undergone repairs to the track rod end and previously experienced worn brake discs, the steering and braking feel must be scrutinised. Any pulling to one side during straight-line driving or a vibration felt through the brake pedal during deceleration could indicate that the recent steering or braking repairs have not fully addressed underlying issues or that other components in the steering geometry are now failing. The history of failures involving ball joints and anti-roll bar linkages necessitates a thorough check of the entire front-end suspension assembly. During the test drive, pay close attention to the steering response; any looseness, wandering, or a notched sensation through the steering wheel may point to further degradation in the steering rack or remaining ball joints. Additionally, because the vehicle has a history of significant brake disc wear, the buyer should verify that the braking system provides consistent, firm pressure without any judder or pulling, ensuring that the calipers and discs are performing uniformly across all four wheels.
