这个码是什么意思？
监测到的增压未达到该工况的标定要求。这描述的是控制结果，不能直接证明涡轮增压器损坏。应按该车流程评估气路受阻、控制系统状态与环境条件。所引通用通报记录了与结冰有关、可能伴随动力降低的情况。
故障码描述检测到的异常，不直接指定必须更换的零件。
更换零件之前
记录是否仅在低温出现，并对比目标与实际增压。核对具体发动机的气路与增压控制检测。低温通报不能证明所有 P0299 都需要更换增压器或更新软件。

还能继续驾驶吗？
仅靠故障码无法判断是否适合继续行驶。故障灯闪烁、严重抖动、过热、机油压力报警或制动转向异常都需及时处理。影响车辆控制或发动机安全时，应在安全地点停车并寻求帮助。以车辆手册为准。
