2015 Mercedes-Benz SLK 2.1L Diesel · AT07 AMT

The most recent MOT test conducted on 18 August 2026 resulted in a pass, although this followed an initial failure due to an inoperative windscreen washer. While the vehicle maintained a clean MOT record from 2023 through 2025, the current inspection shows a shift in the maintenance trend. The emergence of several advisories and minor defects suggests that the vehicle is transitioning from a period of negligible wear into a stage where age-related degradation and component fatigue are becoming manifest. With 47,110 miles recorded over an eleven-year period, the vehicle has averaged approximately 4,283 miles per year. This is considered very low mileage for a vehicle of this age, suggesting it has been used primarily for short trips or kept in storage for extended periods. While this low usage preserves the internal mechanical components of the engine and gearbox, it introduces specific risks associated with infrequent operation, such as the degradation of rubber seals, fluid breakdown, and the potential for components to seize or corrode from lack of regular movement. You should pay particular attention to the braking system and front suspension during your inspection. The advisory regarding pitted or scored rear brake discs may result in brake shudder or a pulsating sensation through the pedal during deceleration. Furthermore, the deteriorating dust covers on the front lower anti-roll bar linkage ball joints are a concern; if these allow contaminants to enter the joints, you may hear audible knocking or clunking sounds when driving over uneven surfaces. The cut in the nearside rear tyre, while not currently exposing the internal cords, represents a localized weakness in the sidewall that should be monitored for any signs of further separation or bulging. Given the low annual mileage, it is essential to confirm that the vehicle has adhered to a time-based service schedule rather than relying solely on mileage intervals. Check the service book for evidence of regular oil, coolant, and brake fluid changes to mitigate the effects of chemical degradation. Inspect the tyres thoroughly for sidewall perishing or cracking, which is common in vehicles that stand for long periods. You should also test the 12V battery health and verify that the windscreen washer system is fully functional. Finally, check the underside for signs of surface corrosion or binding calipers, which can occur when a vehicle is not driven frequently enough to clear oxidation from the brake discs.
