Our Verdict
Proceed with caution due to persistent braking system issues and recurring electronic warnings. While the car has passed its most recent MOT, the history suggests a pattern of deferred maintenance regarding wear-and-tear items.
When viewing this A-Class, your primary focus should be the braking system. The MOT history shows a consistent theme of pitted and worn discs; you should negotiate the price to account for a full brake overhaul, as current advisories suggest the discs are reaching the end of their service life. Check the service book specifically for evidence of fluid changes and any past work on the ABS/ESC modules to ensure the 2025 failures were properly resolved rather than just cleared.
Additionally, test drive the car thoroughly to ensure there are no lingering warning lights on the dashboard, as the Engine MIL and ABS faults were previously flagged. Listen for any uneven braking performance or pulling to one side, which could indicate that the 'fluctuating' brake issue noted in 2025 has returned.
As a 2.1-litre diesel, this A-Class offers strong torque and decent motorway fuel economy, though it will sit in a higher VED bracket than smaller petrol variants. Insurance costs will be moderate, but prospective buyers should factor in the premium nature of Mercedes-Benz parts when budgeting for maintenance.
Annual running costs, including fuel, insurance, tax, and an allowance for the inevitable brake and tyre replacements, will likely fall between £1,400 and £1,800. Keep a contingency fund specifically for electronic diagnostics, given the vehicle's history of sensor-related faults.
Inspect all four brake discs for visible pitting and scoring, as these have been flagged in three consecutive MOTs. Ensure the tyres have sufficient tread, as the front pair were noted as being close to the legal limit during the February 2026 test.
Check the dashboard for any flickering warning lights, specifically the ABS, ESC, and Engine Management icons. Given the 2025 failure history, it is vital to confirm that the electronic systems are communicating correctly. Finally, check for any signs of uneven tyre wear, which could suggest alignment issues resulting from the previous suspension or braking component stress.
This 2014 Mercedes-Benz A-Class with the 2.1L diesel engine has covered 98,821 miles, which is broadly average for its age. The vehicle has a mixed MOT history, featuring multiple failures in early 2025 related to ABS, stability control, and engine management systems. While these were rectified to achieve a pass, the ongoing advisories for pitted and worn brake discs across all four corners indicate that the car may require immediate expenditure on its braking hardware.
While specific aggregate data is unavailable, the A-Class of this generation is known to be sensitive to battery health, which can often trigger false electronic warning lights.
