对于老款车型（B8和B9），车主经常反映存在一些问题，例如由于直喷系统导致的进气阀积碳、水泵和节温器壳体泄漏以及PCV阀偶尔故障。不过，最新的2026款“PPC”平台车型旨在通过升级发动机架构和热管理系统来解决这些问题。

For older generations (B8 and B9), owners frequently report issues such as carbon buildup on the intake valves due to the direct-injection system, water pump and thermostat housing leaks, and occasional PCV valve failures, though the latest 2026 &#34;PPC&#34; platform models aim to address these through updated engine architecture and thermal management.
