2024 Audi RS6 4.0L Twin-Turbo — Engine Diagnosis 🔧
The RS6 can handle a lot. But not everything.
This engine came in after severe overheating, and the damage is extensive.
During diagnosis we found:
• Melted and heat-damaged plastic components
• Broken timing chain on one bank
• Bent valves
• Damaged camshaft adjuster
• Camshaft seized on one bank
• No compression across the cylinders
This is what severe overheating and extreme engine stress can lead to.
This is just the diagnosis. Stay tuned as we bring this RS6 back to life.
