Two problems related to fuel injection have been reported for the 2006 BMW 325. The most recently reported issues are listed below.
The contact owns a 2006 BMW 325i. The contact stated that when sitting idle for a few hours, the vehicle would hesitate to start. The contact would have to pump the accelerator pedal to assist the vehicle in starting. The vehicle would also exhibit a pumping noise while attempting to start. The dealer diagnosed that there was a fuel injection pump defect. The manufacturer was also contacted but denied any assistance with repairs to the vehicle. The vehicle was repaired. The failure mileage was 100,019 and the current mileage was 103,775.
BMW 325i has an acceleration delay problem. When the driver demands a sudden increase in acceleration, the car hesitates anywhere from 1. 5 to 3 seconds. I too have experienced this problem on my recently purchased 325i. Initially thought it was the transmission, however the transmission seems to work fine in manual and sport mode. I only experience this defect during automatic mode. As stated this is a dangerous condition when someone is making a left turn in traffic, or getting onto a highway, or passing on a 2 lane country road, etc. Problem is recurrent.
