刚才在网上搜到的不知道深圳这边有这消息吗 [重要通知] 新3系早晨冷车刹车踩不动，无法着车的请进 3系有一批车确实有这样的问题，BMW也已经证实，去年还没有解决方案，现在已经有了。是需要换助力泵上的一根真空管，主要是由于真空管内的单向阀在停车时间较长漏气造成的。更换后就可以解决了，是BMW免费更换的。 Measure no. 6621808-02 Subject Hard brake pedal pressure / engine start not possible Release date (mm/dd/yy) 5/14/07 Status Approved Organization CN, CAR Vehicles affected E series E81 E87 E90 E91 E92 E93 Engine Body Production period (from/to) (mm/dd/yy) / 8/31/07 Comment on production period Feedback (all cases relating to measure up to) (mm/dd/yy) Complaint Hard brake pedal pressure after vehicle parked up for long period.
