Audi A52018

• Strong styling and refined cabin; excellent motorway refinement, but watch for DPF blockages — common on 2018 diesel A5s, especially if driven short trips. Budget €800–€1,200 if fault codes appear.
• Pricing up 7% year-on-year and solid demand; median mileage at 186k km sits above typical Irish 8-year usage, so negotiate on wear and service history quality rather than age alone.
• Diesel injector deposits and EGR carbon buildup are recurring headaches on this generation. Ask for full service records; rough idle or limp-mode codes are red flags costing €400–€800 per injector or €500–€800 for EGR work.
• Before purchase, request live OBD diagnostic scan focusing on DPF and EGR fault codes — do not rely on dealer verbal assurance. Check recent servicing at Audi or trusted independent specialist.
• NI import saves ~€1,569 before VRT applies on top — factor full tax and registration costs into final budget; no meaningful saving if DPF or injector work looms.
