The 2014 Audi A3 S Line TDI falls slightly short of the UK average, with a first-time pass rate of 76.5% against the national 80%—a modest reliability gap that suggests these diesels are a touch more prone to faults than average, though nothing alarming. The good news is there are no dangerous defects recorded across the 821 vehicles analysed, so safety-critical failures aren't a concern with this model.

At nearly 95,000 miles on average, these cars have covered typical mileage for their age, and the 0.46 failures per vehicle indicates that when problems do arise, they tend to be minor rather than systemic. Before committing to a purchase, have a pre-buy inspection focus on diesel particulate filter condition and turbo health, as TDI engines in this era are prone to expensive issues in those areas if maintenance records are weak.

The 2014 Audi A3 S Line TDI passes its MOT first time more often than most UK vehicles (90.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
