2014 Mercedes-Benz E 2.1L Diesel · NA61 SSS

The 2.143-litre diesel E-Class typically returns around 50-60 mpg on longer motorway runs, though real-world figures in town driving may fall to 40-45 mpg. As a 2014 vehicle, it will sit in a higher road tax bracket than newer Euro 6 models, so check the current VED band before purchasing and budget accordingly. Insurance for the E-Class tends to fall in groups 30-38 depending on the exact variant, so obtain a quote before committing to the purchase.

Diesel servicing on this model tends to be more expensive than on smaller engined equivalents, with annual maintenance typically ranging from £400 to £700 depending on whether the work is carried out by a main dealer or an independent Mercedes specialist. Common replacement items such as brake discs and pads, tyres, and diesel-specific components like the EGR valve or DPF can push costs higher. Given the low recorded mileage, major service items may not have been triggered as often as they would on a higher-mileage example, so verify when the last full service was completed.

Estimated annual running cost: £1,200-£1,600

Although the MOT record is clean with no failures or advisories, a physical inspection should focus on areas that an MOT test does not cover comprehensively. Inspect the underside of the vehicle for any signs of corrosion, particularly around the wheel arches, sills, and subframe mounting points, as the E-Class of this era can be susceptible to surface rust. Check that all electrical systems function correctly, including the infotainment unit, climate control, and any optional equipment such as the electric seats and panoramic roof, as repairs to Mercedes COMAND systems can be costly.

The model-level data highlights suspension arm issues and engine MIL (malfunction indicator light) problems as the most common MOT failure causes for this generation of E-Class. Even though this specific vehicle has not recorded any such defects, pay close attention to the condition of the front suspension arms and bushes for any signs of wear or knocking, and ensure the engine warning light illuminates and extinguishes correctly on ignition. Also inspect the exhaust system for any signs of corrosion or blowing, and check the condition of the diesel particulate filter using a diagnostic tool, as DPF issues are common on low-mileage diesels that have been used for short trips.

Finally, verify the operation of the AdBlue system if fitted, as failure to top up AdBlue can prevent the engine from starting, and replacement of the AdBlue injector or pump can be expensive. Check all fluid levels and their condition, look for any signs of oil leaks from the engine or transmission, and ensure the vehicle drives smoothly through all gears with no warning lights illuminated on the dashboard.
