Advice for buyers
What should I look for in a used Audi A3 saloon?
Check the bodywork for scuffs caused by car parking in tight spaces and look at the alloy wheels for any kerb damage.
There have been a number of issues relating to the A3’s long-term use, most notably a problem relating to rattles from the 1.4 TFSI engine, traced to vibration of the wastegate actuator rod. Diesel particulate filter warning lights have been known to come on, although driving the car on an open road for a few minutes is usually enough to turn it off again. There have also been issues with clutch failure, so check its operation carefully.
Rear hub carrier
On certain A3s produced between 1 August 2017 and 31 August 2017, there was an issue with the rear hub carrier not being manufactured to the correct standard, so in extreme circumstances, the car could lose a rear wheel. A recall was issued to replace the carriers on affected cars.
Vehicles produced between 30 June 2014 and 15 November 2014 had to have their passenger-side airbag module replaced because of a faulty weld on the gas generator inside. In extreme circumstances, internal components could break off, enter the interior and cause injury.
Rear head restraint
Poor welds attaching the rear headrest to the rear backrest of some A3s manufactured between 20 May 2018 and 2 September 2018 posed a safety issue. Affected cars had to have the whole backrest replaced, so check with your dealer that this has been done.
All diesel models will come equipped with a diesel particulate filter (DPF) that’s designed to trap soot from the exhaust and then burn it off later. If the DPF light comes on, you must take the vehicle on a longer drive at a higher speed to clear the filter.
