问：想知道此检查引擎代码190302的意思是什么

该代码涉及燃油箱通风/清除系统泄漏。三年前，宝马发布了技术服务公告-TSB该记录是代码的常见原因，即压力开关有缺陷。尽管其他故障可能会导致代码，但应在诊断早期评估TSB的焦点的开关。With the TSB in hand, you can first ask a BMW dealer if the repair is relevant in your case (the switch can be tested readily) and if relevant, are they willing to cover the repair as a goodwill gesture as some failures documented in TSB’s are repaired by car manufacturers as if the vehicle was still under warranty. If they are not willing to do that, a YourMechanic professional can evaluate the code, find the cause of the fault and if it is the part identified in the TSB make the repair. If the fault lies elsewhere in the fuel tank ventilation system, obviously a different repair would be required and the mechanic would handle that as well. If you desire a repair, simply request a检查引擎灯诊断机械师将在您的位置解决此问题。如果您有进一步的疑问或疑虑，请随时重新连接您的机电，因为我们希望您充分利用修复美元，并帮助您获得最佳的结果。万博体育入口
