Category: Estate car
Superb quality, comfort and refinement make the practical Audi A4 Avant one of the best used estates you can buy.

What should I look for in a used Audi A4 estate?
When viewing a used car, always follow our used car buying checklist.
Check that the seats lower and raise as they should, and take a look at the alloy wheels for any kerb damage. Also check the front and rear of this long car for any scuffs and bodywork dings.
Infotainment system
Problems with the Audi A4 Avant's infotainment system are a cause for concern, with phones not connecting properly and flickering screens being the main complaints. The latest software from Audi can cure some of these ills. Despite the A4’s reputation for having a great interior, there have been some issues with rattling parcel shelves and buzzing from interior trims.
DPF issues
There are no specific diesel problems to be aware of, other than diesel particulate filter (DPF) issues that can affect modern diesel engines if they don’t get hot enough for the DPF to regenerate. If the majority of your driving will be short urban trips, then a petrol-engined model is a better bet.

Used Audi A4 Avant reliability: the owners' view
In our latest Reliability Survey, Audi A4 owners across both petrol and diesel models from 2015 to 2024, said their cars delivered a mixed reliability record. Several owners reported persistent issues with electrical components, particularly malfunctioning infotainment systems and faulty warning lights. Others noted problems with the automatic gearbox, including jerky changes and the need for costly repairs outside of warranty.
Diesel models were more likely to suffer from DPF (diesel particulate filter) issues, with some readers facing expensive bills after repeated regeneration failures. A few owners also mentioned engine management light warnings, often recurring even after dealer intervention.
Dealer service experiences varied. Some praised efficient, courteous service, but others expressed frustration with slow diagnostics and repairs, especially when dealing with recurring faults. A number of readers said they felt dealers were reluctant to acknowledge known issues without prompting, denting confidence in aftersales support.
