Top Mercedes-Benz A-Class fixes every owner should know

TL;DR

The Mercedes-Benz A-Class is stylish and practical but has common faults like electrical issues, suspension wear, brake problems, turbocharger failures, and air conditioning issues. Costs for repairs vary, with DIY options available for some fixes, while others are best left to professionals.

Electrical Issues

Electrical faults are a common problem in older A-Class models, particularly those from 2013 to 2018. Symptoms can include dashboard warning lights and malfunctioning infotainment systems. A simple reset of the battery might solve minor issues, while more complex problems, like faulty wiring, may require professional diagnostics. DIY battery reset is free, while garage diagnostics can cost around £60 to £120.

Suspension Problems

Models from 2012 to 2018 often experience suspension wear, particularly in the front struts and bushings. This can lead to a bumpy ride and uneven tyre wear. Replacing worn struts and bushings is necessary for optimal performance and is a garage job due to the tools required. Parts can range from £100 to £200, with garage labour around £80 to £120.

Brake Component Wear

Brake issues, particularly with the pads and discs, are common in A-Class models from 2015 onwards. Signs include squeaking noises and reduced braking efficiency. Replacing brake pads is typically a straightforward DIY job, but discs may need professional help due to the complexity. Brake pads cost around £50 to £100, while discs can be £100 to £150. Garage labour for a full brake job is usually £60 to £100.

Turbocharger Problems

A-Class models with the 1.6 and 2.1-litre diesel engines (2013-2018) may suffer from turbocharger issues, often due to oil starvation or boost leaks. Turbo replacement is necessary if the unit is damaged, and this is best handled by a garage. Turbocharger parts can cost between £300 and £600, with labour charges adding another £100 to £200.

Air Conditioning Failures

Air conditioning issues are reported in A-Class models from 2014 to 2019, often due to leaks or compressor failures. Recharging the system can be a temporary fix, but locating and sealing leaks is essential for a permanent solution. A recharge typically costs £50 to £100, while a full repair can reach £200 or more, depending on the problem. Garage labour can vary between £60 and £120.
