Audi A62020

• Diesel A6 holds value well in Ireland — 17.7% year-on-year uplift reflects strong demand for premium saloons and proven reliability at this age.
• AdBlue heater failures and DPF clogging are real concerns; avoid cars with suspiciously low annual mileage (under 10k km/year), which trap soot and trigger forced regeneration costs.
• Electrical faults (infotainment, climate, locks) common — verify all functions work, request recent software update history from seller, and budget for dealer diagnostics if glitches emerge.
• Before purchase, pull full service history and check for any DPF regeneration warnings or AdBlue system fault codes; a mechanic's pre-buy OBD scan is essential.
• Median mileage near top of range suggests average use; confirm NCT status and next tax renewal date, as motor tax on CO2 remains modest for this efficient diesel.
