AI Market Summary

Diesel A3 strong on motorway efficiency and running costs; 8-year-old examples hold value well in Irish market with steady 6% annual appreciation.
At median €17,495, fairly priced against rivals—not a bargain, but reliable alternative to petrol equivalents if DPF and EGR issues avoided.
DPF clogging common on urban or short-run examples (€800–€1,500 fix); EGR carbon buildup causes rough idle (€500–€900); dual-mass flywheel wear likely above 160k km.
Before buying, request full service history and run engine cold—rough idle or limp-mode warnings flag imminent EGR or DPF work; check clutch feel under load.
