This post is about finding new things about 1 particular personal observation. At iddle i can hear the diesel engine, at cruising I can hear the diesel engine and that doesn't bother me. I know it is a diesel and it will sound that way always .Yes I did test drive the car and noticed the engine rattle/clatter at the beginning of the acceleration. Even knowing that particular noise i went ahead and acquired the car. The fuel efficiency of this car is awesome despite my heavy foot (better gas mileage than my 335i) and power is great! Fill up is every 2 weeks and would not changes it for a 35i

Again I'm not disappointing about the x5 35d nor I don't like it. I love the dam SAV..
BUT, There is always someone that knows something you don't know

Facts I know :
1- When cold the engine will be louder
2- X5 35d% has an extra fuel pump (high pressure) as oppose to their siblings that may contribute to this extra noise
3- 335d has a lower stance thus reducing the noise travel

Anyway thanks for all your comments.
