Audi A42021

• **Diesel engines need close attention:** DPF regeneration problems and injector coking are common on this generation—budget €800–€1,500 for DPF cleaning/replacement if not recently serviced.
• **Strong market demand and rising prices:** Prices up 16% year-on-year; median €31,250 is fair for the spec and mileage, but shop carefully—38 active listings offer choice.
• **Check service history meticulously:** Request proof of regular short-trip avoidance and DPF regeneration cycles; urban-only driving accelerates carbon buildup. Neglected servicing = expensive repairs ahead.
• **EGR valve and fuel injector risks:** Stop-start city driving worsens carbon deposits on EGR and injectors—ask seller if any warning lights or rough starting occurred.
• **NI import €419 cheaper before VRT:** Factor full VRT (€2,500+), NOx levy, and registration costs; genuine saving only if you handle cross-border logistics.
