Advice for buyers
What should I look for in a used Audi A6 estate?
This is a very large car so check the front and back for scuffs and dents, and the alloy wheels for any kerb damage. Check that all the electrical equipment works as it should, including sat-navs, seat motors and climate control. Check the electric rear tailgate too.
It’s too early in the life of this particular A6 to identify specific problems, but the number of faults on the older model was relatively low. Among them, problems with the car’s infotainment system were a cause for concern, with phones not connecting and flickering screens being the main complaints. The latest software from Audi can cure some of these ills. Despite the old A6’s reputation for having a great interior, there were some issues with rattling parcel shelves and buzzing from interior trims.
Panoramic sunroof glass
There's a possibility that the glass fitted to the panoramic sunroof of some cars built between 16 July and 10 October 2018 could become unstuck from the frame. Check with an Audi dealer whether or not your A6 is affected by this, because the glass will need to removed and stuck back into place if it is.
Is a used Audi A6 estate reliable?
The latest A6 wasn't included in the latest What Car? Reliability Survey. However, Audi as a brand didn't do as well as BMW (ninth place), coming in 22nd overall place out of 31 car manufacturers in the same survey. It did finish ahead of Mercedes in 26th, though.
