Engine and gearbox

One of the most frequently mentioned issues with the 2014 to 2019 Audi A4 is related to its engines, particularly the 2.0-litre TFSI petrol units. Many owners report high oil consumption, leading to frequent top-ups and potential underlying engine wear. Transmission problems are also a concern, especially with automatic versions, where symptoms like delayed gear changes and rough shifting may arise from solenoid failures or torque converter issues. Checking service records for transmission maintenance is advisable when considering a used A4.

The diesel variants, while generally reliable, can experience issues with the diesel particulate filter (DPF), especially if the vehicle has been predominantly used for short journeys. Regular long drives can help mitigate this problem.

Electrics and electronics

Electrical issues are not uncommon in the Audi A4. Owners have reported problems with the infotainment system, including screen freezes and Bluetooth connectivity issues. Additionally, some have experienced malfunctions with the start-stop system, which may not engage as intended. Another area of concern is the vehicle’s lighting system, where some A4s have had issues with LED headlights flickering or failing altogether. Testing all electrical components during a pre-purchase inspection is advisable to avoid unexpected repair costs.

Body and suspension

The bodywork of the 2014 to 2019 Audi A4 is generally well-built, but some owners have reported issues with paint quality, particularly on darker colours, where chips and scratches may be more noticeable. Regular maintenance and touch-ups can help keep the car looking good. Suspension problems, particularly with the front struts, have been noted by some owners, with symptoms including knocking noises over bumps or uneven tyre wear. If you notice any unusual sounds during a test drive, having a mechanic inspect the suspension components could be worthwhile.
