Cause 原因: Unfavourable DME and EGS application. 不利的DME和EGS应用程序. Measure 措施: In the event of a customer complaint, flash program the vehicle using Progman V27.0 (expected to be available in September 2007) or a more recent version. A parts replacement does not provide a remedy. 如果有车主投诉,通过用Progman V27.0(可能会在2007年9月份可用)或者更新的版本对车辆编程. 更换零件是没有效果的.
