Audi A72023

Known issues

• DPF regeneration issues and DPF blockage, particularly on vehicles with low-mileage or urban driving; can result in limp mode and expensive cleaning/replacement (€800–€1,500)
• Diesel particulate filter (DPF) and selective catalytic reduction (SCR) system complexity; AdBlue fluid consumption anomalies and NOx sensor faults reported
• Turbocharger carbon build-up and occasional turbo lag or boost pressure loss on high-mileage examples; turbo replacement €1,200–€2,000
• Electrical gremlins: MMI infotainment system unresponsiveness, software glitches, and occasional navigation freezing; firmware updates sometimes resolve but can be costly to diagnose
• EGR valve carbon deposits on diesel engines (less common than petrol but can occur); manifold cleaning required if carbon build-up causes rough idle or smoke
• Timing chain stretch or noise on higher-mileage units; early warning signs are rattling on cold start (chain replacement €1,500–€2,500)
