Audi A62025

Known issues

• Battery capacity loss: reports of 5–10% degradation within first 3–5 years on Audi PHEV models, reducing electric-only range and hybrid efficiency
• Charging port and DC charging issues: slow charging, intermittent connection faults, and software glitches preventing charge initiation reported on early PHEV A6 units
• High-voltage system overheating: 48V–400V junction box failures causing loss of electric propulsion and limp-home mode, particularly in warm climates
• Timing chain rattle on cold start: some 2.0 TFSI petrol variants exhibit brief chain noise on initial ignition; not safety-critical but indicates wear
• DSG gearbox lag in hybrid mode: judder or hesitation when transitioning between electric and petrol power, exacerbated by software calibration issues
• 12V auxiliary battery drain: PHEV management systems can over-discharge 12V battery, leaving vehicle unable to wake high-voltage systems

Good for

• Smooth, refined commuting on electric power for daily runs under 60 km with full charge
• Tax efficiency: low official CO₂ emissions (80–95 g/km) eligible for reduced company car tax and VRT benefits in Ireland
• Luxury cabin comfort, intuitive MMI infotainment, and premium interior quality
• Decent motorway efficiency when petrol engine is warmed; 50+ mpg achievable on motorway runs if battery is pre-charged
