BMW is also a familiar BMW that makes machine foot glue into vulnerable parts.

发动机做为动力来源，一旦启动，它就时刻在震动，为了减缓它的震动传导车身，所以就有了这个机脚胶。一旦机脚胶损坏，那么发动机与车架就可能产生共振，从而造成各种抖动，还有异响，开车与乘坐都会很不舒服。

As the power source, once the engine is started, it vibrates all the time. In order to slow down its vibration and transmit it to the body, there is this foot glue. Once the foot glue is damaged, the engine and frame may resonate, resulting in all kinds of shaking and abnormal noise. Driving and riding will be very uncomfortable.

机脚胶损坏故障现象就是漏油下榻，机脚胶有液压油减压功能,主要的目的都是一样的，缓存减震的作用。

The fault phenomenon of machine foot rubber damage is oil leakage. The machine foot rubber has the function of hydraulic oil pressure reduction. The main purpose is the same. It can buffer and shock absorption.

当机脚胶出现漏油损坏下榻到底,发动机直接机脚胶接触，与产生的振动会使整个车身处于振动中。

When the foot glue leaks and damages the bottom of the bed, the engine will be in direct contact with the foot glue, and the generated vibration will make the whole body vibrate.

故障现象：

Fault phenomenon:

当发动机机脚胶下榻后，车子的故障不会很快体现出现，所以大家不会太在意。但是当机脚胶下榻到底的时候就会很明显了。

When the engine foot glue stays, the car's fault will not appear soon, so we won't care too much. But when the foot glue stays in the end, it will be obvious.

主要出现故障就是方向抖动、座椅振动，车身共振，我们都知道车子很多原因会导致抖动。

The main faults are direction jitter, seat vibration and body resonance. We all know that the car jitters for many reasons.

不过大家都知道、宝马机脚胶算是经常出现故障的了，如果你的车子遇见了下面这些现象，建议先检查机脚胶。

However, as we all know, BMW foot glue often breaks down. If your car encounters the following phenomena, it is recommended to check the foot glue first.

一、当冷车启动，挂D/R档原地怠速时发动机抖动明显，热车后抖动变轻或者故障，那有可能是机脚胶橡胶受热胀冷缩变化。

1、 When the cold car is started and the D / R gear is engaged, the engine jitters obviously when idling in place. The jitter becomes lighter after the hot car or the fault is eliminated. It may be that the rubber of the machine foot expands and shrinks due to heat.

二、在怠速或低速下，能明显的感受到方向盘上、座椅会有共振。

2、 At idle or low speed, you can obviously feel the resonance of the steering wheel and seat.

三、行驶过减速带等不平的路面，机脚胶损伤下榻的情况下会听见明显的异响。

3、 When driving over the uneven road surface of the deceleration belt and the machine foot rubber is damaged, you will hear obvious abnormal noise when staying.

维修方案：

Maintenance scheme:

只有更换，因为内部的液压油，在生产的时候已经加注好。无法进行维修。

Only replace, because the internal hydraulic oil has been filled during production. Unable to repair.

我们建议整对进行更换，因为当一个出现故障了，那长久故障使用，也导致另一个机脚胶损坏。

We recommend replacing the whole pair, because when one fails, the long-term failure will also lead to the damage of the other machine foot glue.

而且如果只换一个还容易造成高度不一致的问题。导致发动机一直不平衡状态。也有可能导致其他水管损坏。

Moreover, if only one is changed, it is easy to cause the problem of high inconsistency. The engine is always unbalanced. Other water pipes may also be damaged.

更换这东西技术含量不高，但是大家在更换时，一定要买正品。很多假的机脚胶都没有液压油，直接是实心的橡胶塑成。那缓冲的效果就会差很多，而且使用的时间也不长。

The technical content of replacing this thing is not high, but we must buy genuine products when replacing it. Many fake machine feet are made of solid rubber without hydraulic oil. The buffering effect will be much worse, and the use time will not be long.
