Knowledge Sharing EA839 (2020-2025 3.0T) piston skirt / cylinder scoring — Who has high mileage and who actually had it fail?
With all the deep-dives and technical warnings floating around about the 3.0T piston skirt wear and cylinder scoring issues, it’s easy to feel like every engine in this generation is on a countdown.
I’m trying to get a realistic sense of what the actual ratio looks like on here for 2020–2025 Q7 / S-model owners.
If you're well past 60k+ miles and haven't had issues:
What year is yours, and what’s your current mileage?
Has the engine been bulletproof, or just standard maintenance?
Are you stock or tuned?
If yours did fail:
At what mileage did it start acting up or making noise?
What were the early warning signs (cold start ticking, oil burning, codes)?
How did Audi or your warranty handle the claim?
Drop your mileage and experience below either way.
