近期发现很多smart变速箱出现问题，SMART群里面有个QP大侠就出现过一些轻微问题，这问题到了4S店又消失，时好时坏。垃圾4S电脑检测没有故障码，就放弃了其他检查，这是对车主的不负责态度，强烈谴责。非要等离合器报销了才能说出故障来？那时候4S又能大捞一笔了。不知道是4S无知呢？还是专门欺负广大用户无知呢？
现在让大家了解一些真相。与正规的维修方式方法。
希望能够避免将来动不动就换离合器，动不动就几万的维修费。别让4S黑了大家。4S真是坑人。
他们无知么？肯定不是的。少了这部分调整保养，将来的维修成本将会更高。因此，造福大家，与人分享。
水平不高，翻译不精，挑重点说，水平高者直接看原文。
On every service, smart adjust the bite and release point of the clutch to ensure
it works within its tolerances. Problems begin when you stop paying smart's extortionate
prices and go to a 3rd party specialist. Some specialists don't have the hardware needed
to adjust the clutch so it is often overlooked.
在调整服务中，智能的调整离合器结合点和释放点，以确保它在工作范围内的运作。
当问题出现时，一些专家常常忽视硬件方法调整离合器。
If you use them for a service, ask for your clutch to be adjusted.
Most will do it free as part of the service but some will charge you.
如果你要求他们对你的离合器进行调整的服务，正常情况下，调整它应该是免费的，但有些人会向您收取这些费用。
Clutch adjustment problems are easy to determine. Pulling away up hill can cause
the engine to sound like it's choking or bogging down. You may also notice that the
car over revs during gear changes especially when cold. If you leave it, you will
eventualy find that the revs rise but no power is being transfered to the wheels
as the torque eventually causes the clutch to slip over the friction plate.
Clutch adjustment can be done in 2 ways (preferably both).
如果你的离合器需要调整，问题很容易确定。当发动机提高负荷的时候，发动机声音会有所变化，听起来工作不正常。
可能还会注意到，发动机转速特别高的时候，发动机转速上升，此时没有动力或者微弱动力传递到车轮，特别是冷车的时候这种现象更加严重。最终导致离合器打滑
离合器调整可以通过两种方式（最好是两项同时进行）
机械调整 （这部分有动手能力的可以亲自动手做）
Look under the car, just off to the left near the intercooler scoop you will see the sight below. Using an
E10 Torx socket loosen the 3 bolts indicated below.
在你的车下面变速箱附近你会看到下面照片的东西。
使用E10梅花套筒扳手松开下面3个螺丝。
With all 3 bolts loosened, slide the unit towards the centre of the car (to the right).
The actuator will only move about 2mm or 3mm before you feel it hit an obstruction.
Stop pushing the actuator and it will move a fraction back to the left by itself.
Give it a 5 seconds to settle and tighten the 3 bolts back up
3颗螺丝完全松开后，伺服电机可以向右滑动，移动2-3毫米左右，当推入伺服电机杆后，你会觉得已经到头，内部有了障碍物，推不进去了，将这个位置记录，再往左略微调整一点，以确保里面离合器轴承的自由间隙。
调整完毕，最后，拧紧之前松开的三颗螺丝。
With that simple task completed, the actuator is in the perfect position to allow the car to fully open and close the actuator and allowing the clutch to move properly.
这个简单的调整工作完成以后，伺服电机换挡机构应该是在完美的位置上，让离合器完全打开或者结合。并让离合器正确的动做。
With that done, it is a good idea to 'teach' the car the new clutch position. This is called the bite and release point. With the actuator pushed in, the face of the clutch is moved slightly inwards as well. Ideally, the car should know where the clutch face is.
完成这些工作以后，让变速箱找到新的接合点的位置。这就是开手动挡车型的咬合点。理想情况下，离合器的咬合点是固定的。
电脑调整（就是4S店所谓的升级电脑程序，简直就是忽悠人。其实说简单了就是一个离合器位置设定）
This electronic adjustment needs to be done on specific equipment like a Mercedes Star machine or the portable version called Win-Star. Booking in with smart or (more sensibly) the any of the companies mentioned above will get the clutch electrically adjusted in under 10 minutes. Both systems plug directly into the OBD port.
电脑调整需要有专用电脑或者笔记本电脑，软件称为WIN-STAR，10分钟内可调整离合器位置。可以通过OBD接口进入车辆系统。
（这部分其实就是用电脑进行离合器初始化设定，4S升级电脑就是大同小异的这么进行一次设定）
This electronic adjustment needs to be done on specific equipment like a Mercedes Star machine or the portable version called Win-Star. Booking in with smart or (more sensibly) the any of the companies mentioned above will get the clutch electrically adjusted in under 10 minutes. Both systems plug directly into the OBD port.
Watching the Win-Star system in action isn't particularly interesting but listening to everything moving in the engine is fascinating. Teaching the bite and release points moves the actuator through a few movement with the engine off. You can hear the clutch moving and working out where the clutch is and where the actuator should be sitting.
The adjustment is over in a few seconds but makes the car so much better
than what it was. Try not to leave an un-adjusted clutch too long as it can
cause glazing which reduces friction which will cause it to slip further. Slipping
causes heat and heat will kill your clutch stone dead.
If you do kill it dead, you have a few options. If you have a standard car then just have the normal clutch fitted, slightly modified for power you should get a Roadster clutch. All out power smart owners should consider the Brabus Roadster clutch. Each one can handle slightly more power than the last.
If you consider your smart to be 'race spec' then consider contacting Smartarse Design regarding the Bonalume performance clutch. Many attributes have been tagged to this 3rd party clutch which I won't go into here. Needless to say, it's better than a standard, costs £650 fitted (almost the same as a clutch from smart). With that you get a lighter fly wheel installed.
A lighter flywheel will allow the engine to rev quicker, will slightly increase the BHP transfered to the wheels but will slightly reduce torque.
这段话是电脑调整的方式方法，我们都没有软件能进入，就不全部翻译了。挑重点说。
调整离合器不能调整过度，如果调整过度会让你开车感觉好很多，如果离合器伺服电机杆推进过长，他会和离合器接合力更低，这样会导致离合器进一步打滑（也就是因为打滑，减少了顿挫感，让你感觉驾驶起来更舒适。）长时间打滑产生的热量会导致离合器损坏，烧毁。（原文中用杀死来形容）。
如果你车的离合器损坏（非BARBU版本），会有几个选择，选择原车配套的标准离合器。如果你想改装，可以选择BARBUS高性能跑车离合器，它能够更高限度的承受功率。相比较轻的飞轮压盘，也会增加发动机功率，但会略微降低扭力。
帖子编辑完成。用了一上午时间。水平太次了。估计看的人不多。只要有一个能看懂的，就算是造福了。看不懂的就当看一个热闹吧。呵呵。
