问:汽车运行粗糙,令人窒息的声音- 2008年宝马528 i xDrive

我不确定你所说的“令人窒息的声音。”If by that you mean "wheezing", this could be an air leak in the intake - loose or leaking vacuum hose - a common problem with high mileage engines. The Service Engine light may be trying to tell you something more than ’Time to change your oil." Have the engine checked for problem codes that may instruct where to pursue the bad behavior. A professional mechanic, like one from YourMechanic, can诊断噪音第一手适当地,让这个问题得到解决。
