Listed from most frequently reported, each with its source.
In some A3 8V diesel models, the water pump (plastic components) has been reported to have low durability, and in some cases, issues with the timing chain tensioner have been reported. Pump failure or malfunction can lead to overheating and more serious damage.
Cooling
In the 1.6 TDI EA288 engine in the A3 8V, incomplete regeneration or DPF clogging is frequently reported, especially with city driving and short trips. This can lead to increased fuel consumption, engine warning light, and the need for intervention or cleaning.
Exhaust Emissions
The EGR valve and recirculation circuit can become clogged with carbon deposits; this can cause idle fluctuation, power loss, and the check engine light to come on. In severe cases, cleaning or replacement may be necessary.
Exhaust Emissions
Although the second-generation 1.6 TDI (EA288) has improved reliability over previous versions, some users still report faults or issues with the common rail injection system (injectors, sensors).
