Elevated Risk Zone
At this point, wear items are more pronounced. Proactive inspection of engine components (e.g., carbon buildup, oil leaks), transmission, and all advanced electronic systems is vital to prevent major failures.
High Risk Zone
An RS5 reaching this mileage indicates good prior maintenance. However, all major components are approaching or exceeding their expected lifespan. Be prepared for significant component replacements (turbos, transmission, engine reseals)…
