The metal rattle came from the front of the car.

　　加速时，该噪声主要发生在2000 rpm3000 rpm的范围内。

　　When accelerating, the noise mainly occurs in the range of 2000 rpm to 3000 rpm.

　　特约维修站诊断结论：

　　Diagnostic conclusions of special maintenance stations:

　　可以在用户的??投诉中重现错误。

　　Errors can be reproduced in user complaints.

　　该噪声在负载下从涡轮增压器区域传播。

　　The noise propagates from the turbocharger area under load.

　　技术背景

　　Technical background

　　内轴和旁通阀的连杆区域中的衬套之间的公差。

　　Tolerance between bushing in connecting rod area of inner shaft and bypass valve.

　　由于该公差，旁通阀连杆将在特定速度范围内振动。

　　Because of this tolerance, the by-pass valve connecting rod will vibrate in a specific speed range.

　　这种振动会导致旁通阀连杆发出叮当声。

　　This vibration causes the by-pass valve connecting rod to jingle.

　　请分析用户投诉（基于用户声明/技术背景），以便清楚地对此TPI进行分类。

　　Please analyze user complaints (based on user statements/technical background) to clearly classify this TPI.

　　只有完全满足所有必需的标准（型号/型号，车辆识别号，发动机/变速箱型号代码，PR编号，零件号，软件版本，代码...），才能进行以下维修。

　　The following maintenance can only be carried out if all necessary standards (model/model, vehicle identification number, engine/gearbox model code, PR number, part number, software version, code etc.) are fully met.

　　否则，采取此措施将无法故障，并可能导致维修。 在这种情况下，我们保留拒绝解决索赔的权利，而拆下的零件的费用必须由我们自己承担。

　　Otherwise, taking this measure will not eliminate the failure and may lead to maintenance. In this case, we reserve the right to refuse to settle the claim, and the cost of the dismantled parts must be borne by ourselves.

　　如果发生上述问题，请按照以下说明将原始备件目录中给出的卡簧安装在旁通阀连杆上。

　　If the above problem occurs, please install the card spring given in the original spare parts catalogue on the by-pass valve connecting rod according to the following instructions.

　　1）如图所示安装夹子。

　　1) Install clamp as shown.

　　2）将锁扣（箭头1）推向涡轮机壳体。 为了便于安装，应将旁通阀的杠杆和夹子对准。 然后将锁扣推到旁通阀杆上的停止位置（箭头2）。

　　2) Push the lock (arrow 1) into the turbine housing. In order to facilitate installation, the lever and clamp of the bypass valve should be aligned. Then push the lock button to the stop position on the bypass stem (arrow 2).

　　3）安装后，请注意夹子的正确位置。 如有必要，请用镜子检查。

　　3) After installation, please pay attention to the correct position of the clamp. If necessary, please check with a mirror.

　　安装弹性挡圈时无需拆卸零件！

　　There is no need to disassemble parts when installing elastic retaining rings!

　　安装弹性挡圈时，请注意：在安装过程中，请勿过度伸展弹性挡圈或使其弯曲。 如果在安装过程中弹性挡圈过度拉伸，则故障可能无法，并且可能会再次出现噪音。

　　When installing elastic retaining rings, please note that during the installation process, do not overextend or bend the elastic retaining rings. If the elastic retainer is stretched excessively during installation, the failure may not be eliminated and noise may occur again.
