　　Jinan Dual Clutch Transmission Maintenance Guide: Dry vs Wet Fault Analysis, Key Maintenance Points for Different Brands, Experience Sharing with Experienced Drivers

　　在济南，开双离合变速箱的车越来越多，虽然换挡快、省油，但也让不少车主在维修时犯了难。干式和湿式双离合有啥区别？不同品牌的变速箱维修有啥讲究？今天就结合济南本地的维修经验，给大家详细讲讲双离合变速箱的维修知识，希望能帮到大家。

　　In Jinan, more and more cars are driving dual clutch transmissions. Although they shift quickly and save fuel, they also make it difficult for many car owners to repair them. What is the difference between dry and wet dual clutch? What are the maintenance requirements for different brands of transmissions? Today, based on the local maintenance experience in Jinan, I will give you a detailed explanation of the maintenance knowledge of dual clutch transmissions, hoping to help you.

　　首先要分清干式和湿式双离合，这是维修的基础。两者的核心区别在于离合器是否被变速箱油浸泡：湿式双离合的离合器泡在油里，散热好、平顺性高、故障率低，适合大排量发动机，但价格贵、油耗略高、维修成本也不低；干式双离合没有油液浸泡，传动效率高、换挡更快、更省油，但散热差，堵车时容易抖动，甚至出现传动中断的情况。在济南的拥堵路况下，干式双离合的散热问题更突出，这也是维修中需要重点关注的。

　　Firstly, it is necessary to distinguish between dry and wet dual clutch transmission, which is the foundation of maintenance. The core difference between the two lies in whether the clutch is soaked in transmission oil: the wet dual clutch clutch is soaked in oil, with good heat dissipation, high smoothness, and low failure rate, suitable for large displacement engines, but expensive, slightly high fuel consumption, and high maintenance costs; Dry dual clutch transmission does not involve oil immersion, resulting in high transmission efficiency, faster gear shifting, and more fuel efficiency. However, it has poor heat dissipation and is prone to shaking and even transmission interruption when stuck in traffic. In the congested road conditions of Jinan, the heat dissipation problem of dry dual clutch transmission is more prominent, which is also a key concern in maintenance.

　　从故障率来看，这些年双离合变速箱的质量已经有了很大提升。早些年干式双离合的故障率高达 12%，现在已经降到 0.5% 以下，国产和合资品牌都表现不错。但不同品牌的变速箱，维修时还是有各自的特点。

　　From the perspective of failure rate, the quality of dual clutch transmissions has greatly improved in recent years. In earlier years, the failure rate of dry dual clutch transmission was as high as 12%, but now it has dropped to below 0.5%, and both domestic and joint venture brands have performed well. But different brands of transmissions still have their own characteristics when it comes to maintenance.

　　大众的 DSG 变速箱是双离合领域的 “老大哥”，虽然早期问题较多，但经过多年迭代，现在的稳定性在行业内首屈一指。维修大众 DSG 变速箱时，要注意核心零部件的供应商：双离合器来自美国博格华纳，电控系统来自德国大陆，轴承来自德国舍弗勒。如果需要更换这些部件，建议选择原厂配件，以保证维修质量。对于 16 年以前的老款 DSG 变速箱，维修时要格外仔细，16 年以后的则相对可靠。

　　Volkswagen's DSG gearbox is the "big brother" in the dual clutch field. Although there were many problems in the early days, after years of iteration, its stability is now second to none in the industry. When repairing Volkswagen DSG transmissions, pay attention to the suppliers of core components: dual clutch from BorgWarner in the United States, electronic control system from mainland Germany, and bearings from Schaeffler in Germany. If these components need to be replaced, it is recommended to choose original parts to ensure repair quality. For older DSG transmissions before 2016, extra care should be taken during maintenance, while those after 2016 are relatively reliable.

　　德国格特拉克的变速箱也应用广泛，装备在宝马、奥迪、奔驰、奇瑞、长城等众多品牌的车型上。格特拉克的变速箱无论是干式还是湿式，都以寿命长、可靠性好著称，维修起来相对省心，只要选择正规的维修厂和合格的配件，一般都能得到不错的维修效果。

　　The transmission of German Getrag is also widely used, equipped on many brands of car models such as BMW, Audi, Mercedes Benz, Chery, Great Wall Motors, etc. Getrag's transmissions, whether dry or wet, are known for their long lifespan and good reliability. They are relatively easy to maintain, and as long as you choose a reputable repair shop and qualified parts, you can generally achieve good repair results.

　　韩国坦迪斯的变速箱主要装备在现代、起亚的车型上，品质也比较稳定。维修时同样要注意年份，15、16 年以前的车型需要慎重，之后的则可以放心。

　　The transmission of South Korean Tandis is mainly equipped on Hyundai and Kia models, and the quality is also relatively stable. When repairing, attention should also be paid to the year. Models before 2015 and 2016 need to be carefully considered, while those after can be trusted.

　　国产双离合变速箱的进步也很明显。万里扬和青山是专门的变速箱生产企业，虽然初期装车时问题较多，但近几年质量已经稳定了很多，故障率大幅下降，2020 年以后的车型基本可以放心使用。长城的蜂巢易创、比亚迪、吉利、奇瑞等品牌的自研变速箱，也都有不错的表现，部分车型的换挡体验和质量甚至不输国际品牌。维修这些国产变速箱时，核心零部件依然依赖博格华纳、大陆等国际供应商，选择配件时要注意渠道。

　　The progress of domestic dual clutch transmissions is also evident. Wanliyang and Qingshan are specialized gearbox manufacturers. Although there were many problems during the initial installation, the quality has stabilized significantly in recent years, and the failure rate has greatly decreased. Models from 2020 onwards can be used with confidence. The self-developed transmissions of brands such as Great Wall's Beehive Yichuang, BYD, Geely, Chery, etc. have also performed well, and the shifting experience and quality of some models are even comparable to international brands. When repairing these domestic gearboxes, the core components still rely on international suppliers such as BorgWarner and Continental, and when selecting parts, attention should be paid to channels.

　　在济南维修双离合变速箱，建议选择有经验的正规维修厂。维修前要先进行全面的故障检测，确定故障原因，避免盲目维修。对于常见的离合器磨损、机电单元故障等问题，要及时更换相关部件。同时，日常保养也很重要，定期更换变速箱油，保持良好的驾驶习惯，能有效延长变速箱的使用寿命，减少维修成本。

　　When repairing a dual clutch transmission in Jinan, it is recommended to choose an experienced and reputable repair shop. Before maintenance, a comprehensive fault detection should be conducted to determine the cause of the fault and avoid blind maintenance. For common issues such as clutch wear and mechanical and electrical unit failures, relevant components should be replaced in a timely manner. At the same time, daily maintenance is also important. Regularly changing the transmission oil and maintaining good driving habits can effectively extend the service life of the transmission and reduce maintenance costs.

　　总之，济南的双离合变速箱车主，只要了解自己变速箱的类型和特点，选择正规的维修厂，就能有效解决变速箱故障，让爱车保持良好的运行状态。希望这些建议能帮到大家，祝大家用车愉快！

　　In short, owners of dual clutch transmissions in Jinan can effectively solve transmission problems and keep their cars in good operating condition as long as they understand the type and characteristics of their transmissions and choose a reputable repair shop. I hope these suggestions can be helpful to everyone, and I wish everyone a happy car!
