Advice for buyers
What should I look for in a used Audi A6 saloon?
Check the bodywork closely for scuffs picked up in car parks; the A6 is a long car and, despite having parking sensors front and rear, accidents do occur. Also check the alloy wheels for kerb damage.
Make sure that any A6 fitted with an automatic gearbox has had its fluid changed at regular intervals, otherwise, you could be looking at an expensive gearbox replacement in the future. Ideally, both the S Tronic and Multitronic (CVT) automatic gearboxes should have the oil changed at the recommended 38,000 mile limit.
Panoramic glass sunroof
A small number of cars that were constructed between 16 July 2018 and 10 October 2018 and were fitted with a panoramic glass roof could have an issue with the bonding agent used to keep the glass panels in place. Find out from your local Audi dealer if your A6 is affected; it will need to have the panels stuck down again to solve the problem.
There have been two recalls issued for the A6 that concern fuel leaks. The first is for cars made from 1 April 2011 to 30 April 2012, the second is for A6s made between 18 February 2014 and 2 September 2016. Find out from your local dealer if your car is affected.
Particles in the engine coolant could end up blocking the pump and lead to it overheating. This applies to vehicles made between 1 May 2011 and 31 October 2016. Contact your Audi dealer because affected cars will need to have the coolant system checked, and any damaged parts replaced. A software update will also need to be performed.
Reduction in braking performance
On A6s made from 1 January 2012 to 27 August 2014, an issue with the diaphragm in the brake servo rupturing could result in a reduction in braking performance. Any Audi dealer will be able to let you know if your example is affected and will rectify the fault for you.
