What should I look for in a used Audi A4 estate?
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.
The number of reported faults on the A4 Avant is relatively low, although problems with the car’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.
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.
Audi as a brand finished in 20th place out of 31 manufacturers in our most recent reliability survey. The A4 in saloon form finished near the bottom of the executive car class, rather surprisingly, in its diesel variant.
