二手07年的mini cooper s手动挡， 买来一个多月， 昨天开始， 在加速的时候感觉是发动机驾驶这侧有什么东西在摩擦的声音，大概转速上2K以上就有这个响动了，oil service 大概是1年3个月前做的， 想知道下是大概是什么原因呢， 车场买的，发动机这些核心部件还在保修期，
我自己刚开始开手动档， 可能踩离合习惯不好， 有时上坡怕溜就离合油门一起踩 发出很大声，不过也就2-3次， 会不会离合片烧的不行了？还有次换挡 挂3档没挂上 挂到1档 会不会齿轮打掉了？多谢

今天早上冷车也是响 但跑了大概2mile后就不响了

发动机响的原因太多了，什么部位响，什么响声，结果都不同
如果发动机灯没亮，你又想确认，就只有去车厂检查了

怠速的时候是正常的 就是从冷车启动到跑热的过程转速高一点就响 在驾驶员这测感觉什么东西在摩擦的感觉

今天去mini 4s店去做检查 说是timing chain 有问题 本来我的车刚买不到3个月在保修期下 我今天联系卖我的车场， 这么回我的邮件
Reference our telephone conversation just to confirm neither the front tyres or the replacement timing chain is covered under the 3 month driver guarantee on your vehicle.
As discussed if you want to carry out the replacement of your timing chain to remove the noise as a gesture of good will we would happy to make a contribution. We also advise you to get a quote from an independent garage for the timing chain replacement and the front tyres as you could make a large saving on the prices quoted by the Mini main dealer.
附件是mini 4s店的检查报告 4S店在换timing chain 要825磅 现在如果不能保修的话 去garage换一般要多少钱 谢谢大家

我跟卖我的车场又沟通了下 他们说timing chain在保修范围 但是必须是要车不能开了 才给换 这个理由充分吗 我需要跟他们再理论吗

If tread depth is more than 1.6mm, there is no need to replace the tyre. Your car does need to go through a wheel alignment adjust or at least front wheel tracking adjustment. Wheel alignment costs about 100 pounds, tracking around 20 quids. You need to top up your engine oil.
Timing chain should last lifespan of your engine, but when it does rattle, it is a big one to do. It is like changing timing belt on other engines, which cost from £180 to £1000 depends on cars. Audi is the worst. Do negotiate with Mini, they are quite good when it comes to a big repair and normally will offer your a hefty discount, which happened to me a few times back in the old days. 
Get quote from different local Mini dealers including independent dealers, and you will have a better idea how much it actually costs and go back to Mini and try to beat them down on price with the best quote you have.

mini的timing chain的问题，07年以后的mini上挺常见的。等你更新结果，我的是mini one，目前还好，冷车的时候也很响。。

我的07年mini cooper换过timing chain guide， 当时main dealer要1800，后来去了个小车场说200 但他又说没工具搞不了，最后在一个稍大点的车厂花了500，其实楼主如果可以联系卖你车的车场帮忙换 可以ebay买timing chain 套件 包括guide 大概100 main dealer太坑

还有 如果你只换timing chain，新的链条和旧的齿轮在一起会不好兼容，容易跳齿，最好连齿轮换
