2016 Mercedes-Benz CLS 3.0L Diesel · TO07 TTO

The most recent MOT test for this 2016 Mercedes-Benz CLS, conducted on 2026-07-15, resulted in a pass with a single advisory concerning the rear brake discs, which are noted to be worn but not to an excessive degree on both the nearside and offside. The MOT history over the past six years reflects a stable maintenance profile, with no failures or critical defects recorded outside of this minor advisory. The consistent passing of MOTs suggests that the vehicle has generally maintained its roadworthiness, though the advisory indicates a developing condition that requires attention to prevent potential issues with brake performance or disc replacement costs in the near future. The recorded mileage of 58,325 miles for a vehicle of this age—approximately 5,832 miles per year—is notably low relative to typical usage patterns for a ten-year-old car. Such a low annual mileage often suggests periods of prolonged inactivity, which can lead to specific wear and tear concerns. For instance, standing vehicles may experience accelerated corrosion on brake components, particularly discs and calipers, due to oxidation and potential binding. Additionally, fluid degradation can occur more rapidly when fluids are not circulated, affecting hydraulic systems, coolant, and transmission fluids. The lack of higher mileage accumulation implies that wear on consumables such as tyres, suspension components, and drivetrain elements may not be as pronounced as one might expect for a vehicle of this age, but this also raises questions about how the vehicle was maintained during periods of low usage. Given the clean MOT history apart from the rear brake disc advisory, the buyer should prioritise a thorough inspection of the braking system, focusing on the rear brake discs and calipers for signs of corrosion, binding, or uneven wear. During a test drive, listen for any unusual grinding noises when applying the brakes, as this could indicate worn brake pads or metal-to-metal contact on the discs. Also, check for a firm and even pedal feel, as a spongy or soft pedal may signal air in the hydraulic system or a failing master cylinder. The advisory on the rear brake discs suggests that the discs are nearing the end of their serviceable life, and it is prudent to have them inspected or replaced soon to avoid potential brake failure. If the discs are confirmed to be worn beyond the advisory threshold, the buyer should budget for a full brake system overhaul, including pads, shoes, and potentially the rear brake hoses. For the remaining systems, the buyer should conduct a comprehensive physical inspection, particularly given the vehicle’s age and low mileage. Start with the tyres, checking for sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stored in a damp or cold environment. Ensure the tyres have sufficient tread depth, as excessive wear can lead to hydroplaning hazards. Inspect the suspension for signs of wear, such as cracked or swollen coil springs, worn suspension bushes, or excessive play in the struts. A test drive should reveal any clunking noises from the suspension, particularly when driving over bumps, which may indicate failing components. The battery should be checked for corrosion on terminals and a healthy voltage output, as a low-mileage vehicle left unused for extended periods may suffer from battery drain. Finally, verify that all fluids—coolant, brake fluid, transmission fluid, and power steering fluid—are topped up and free from contamination, as stagnant fluids can lead to system failures or reduced performance. If the vehicle has been stored for long periods, consider a thorough fluid flush and a check of the engine’s internal components for signs of wear or damage from lack of use.
