Mercedes-Benz A-Class 2008 to 2014: common problems and what to know

TL;DR

The 2008 to 2014 Mercedes-Benz A-Class has common issues, particularly with its electrics and gearbox. Thoroughly check these areas before purchasing to avoid potential problems.

Key facts callout

• Common problems include electrical faults and gearbox issues.
• Diesel models may experience DPF blockages, especially with short trips.
• General wear and tear can affect suspension and bodywork.
• Owners often report a good driving experience but note potential repair costs.

Engine and gearbox

The 2008 to 2014 A-Class features various engines, including petrol and diesel options. While petrol engines are generally reliable, diesel variants can suffer from diesel particulate filter (DPF) blockages, especially during short trips when the DPF cannot regenerate properly. Gearbox problems are also common, particularly with the automatic transmission, which may not engage smoothly or exhibit erratic behaviour. Test the automatic gearbox thoroughly during a test drive.

Electrics and electronics

Electrical faults are frequently reported by A-Class owners, ranging from minor issues like malfunctioning interior lights to serious problems such as keyless entry failures. Dashboard warning lights may illuminate without cause, so it is advisable to have any electrical issues diagnosed by a professional. The infotainment system, while advanced for its time, can also experience glitches, so ensure all electronic features function correctly before purchasing.

Body and suspension

The A-Class bodywork generally holds up well, but it is crucial to inspect for rust, particularly around the wheel arches and lower doors. While paint quality is typically good, stone chips and scratches can accumulate over time, especially on used models. Suspension issues, though less common, can occur, particularly with the front suspension, leading to a less comfortable ride and uneven tyre wear. Listen for unusual noises when driving over bumps, as this may indicate worn suspension components.
