Advice for buyers
What should I look for in a used Audi A3 sports?
As with any used convertible, check the footwells for any sign of water damage and the roof for leaks. Check that the electric mechanism for the hood works as it should, otherwise it'll be an expensive job to put right. Also check the large alloy wheels for any signs of kerb damage.
There have been a number of issues relating to rattles from the 1.4 TFSI engine, so listen carefully for any noises from the turbocharger. In diesels, the diesel particulate filter warning light has been known to illuminate, although driving the car on the open road for a few minutes is usually enough to turn it off.
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.
Is a used Audi A3 sports reliable?
The Audi A3's reliability (we have no standalone results for the Cabriolet, so here we are using the Sportback's stats) depends on which engine it has. In last year's What Car? Reliability Survey, petrol models finished lower down the rankings in 17th place, but diesel models managed to climb up to the lofty heights of 2nd, just behind the Hyundai i30. In the latest survey, the A3 finished in 18th place out of 24 cars in the family car class.
