宝马7系故障
- F02 730 鼓风机故障 异常响动维修今天下午,突然之间,鼓风机有异响了,尤其是内循环的时候风扇开的很大,有点类似于摩托车的声音,噗噗噗的,声音蛮大的,回来休息了一会儿,决定还是去维修了吧,毕竟夏天,没有空调可不行。鼓风机异响已经拆下来了鼓风机上盖鼓风机已经拆下来了,里面还是蛮脏的,不过还去年我清理过一次,但是也很脏的,一抹一手灰。鼓风机上盖之前记得有朋友问我鼓风机拆吗?我感觉也就是20分钟吧,就拆下来了。已经挂掉的鼓风机上盖,特别脏也破了,网上有卖滤网了,我觉得没必要了,直接190买一个原厂的,师傅在分离鼓风机点机和外壳,还是很快的,全新的鼓风机,对比一下颜色,天呐这个应该是进气翻版,也挺脏的对比一下滤网,差距还是蛮大的,真的挺脏的,顺便我还清晰了一下,蒸发箱,300元全新的上盖老朋友报价中对比中,最后因为距离原因,选择了,这一家,毕竟也没什么技术含量,买一个马瑞利的,质量是,但是,太远了,耽误时间送货过来,最后的拿货价。另外工时收了我,300元清洗蒸发箱,200元拆装费,本次消费930元。希望对你能有所帮忙 查看详情>>

- 宝马七系变速箱异常故障维修案例[{"content":"1. 宝马七系变速箱异常故障现象:\n09年至12年宝马七系变速箱出现异常时,仪表盘显示变速箱有异常谨慎驾驶,发动机转速高、变速箱不换档、提速无力、熄火重启后故障消失,但后续驾驶中故障现象再次出现。\n2. 宝马七系变速箱有异常原因分析:\n该故障属于偶发性故障,前期多天出现一次故障,频率会慢慢增多严重时一天出现好几次,这充分说明变速箱内部机械部分没有问题,因为变速箱内部机械部分出现问题后便箱故障会持续出现,而变速箱有异常故障报警属于偶发性故障熄火后故障消失,这就是犹豫宝马七系的变速箱电脑出现了电子电器间歇性故障引起的。\n3. 宝马七系变速箱异常维修过程:\n(1)宝马七系变速箱异常可能有多种原因引起的,本文通过故障频率较高的故障类型进行介绍希望能够帮到你。\n(2)电脑检测变速箱系统故障码显示400625涡轮转速传感器过小,401012具有相同优先权的两个备用措施现状优先等级二。\n(3)根据故障码显示我们可以得知,该变速箱故障问题是由于涡轮速度传感器信号出现间歇性中断引起的变速箱异常报警。\n(4)速度传感器和电脑连为一体,窝轮速传感器到电脑版的联接线出现问题后就会出现该故障,可以对该问题进行单独维修,无需更换变速箱总成或更换变速箱电脑,可以为您节省几万元维修费用,维修后质量稳定不返修。\n(5)举起车辆放出变速箱油,拆下变速箱油底壳儿,看到的就是变速箱电脑和阀体。\n(6)接着拆下变速箱电脑和阀体总成。\n(7)单独对宝马七系变速箱电脑进行检测维修。\n(8)变速箱电脑维修后安装到变速箱内,安装变相油底壳加注原厂变相油电脑清除故障匹配后试车,宝马七系变速箱异常故障顺利解决。\n4. 宝马七系变速箱异常维修总结:\n09年到12年宝马七系搭载六速手自一体变速箱,该变速箱80%的故障问题都和变速箱电脑和阀体有关,当你遇到宝马七系变速箱异常故障问题时要到专业的自动变速箱维修中心进行检查维修,这种对电脑或阀体具体故障部位进行针对性的维修,即可解决宝马变速箱故障,给你节省大部分的维修费用。","height":0,"order":1,"type":1,"width":0}] 查看详情>>
