| Hi. I have a 2004 BMW 330Ci /auto(i know.. =(..) with sports package/premium package/18 in wheel package. I had it just over 2 month now. I'm getting weird whistling sound from the back of my car when I'm driving at about 85-90 mph. I can consistantly reproduce it by accelerating to about 90 mph then letting the accelerator go a little and slow down to 85mph ish. It's a faint whistling sound from back of the car. I'm taking the car in on wednesday. However, when i called the dealer they said the problem is they won't be able to reproduce it because they can't drive it over 65mph. Any suggestion on what the problem is?
A quick questions. I have over 2000 miles on it now. When should i get an oil change. Dealer said 15,000 miles but I feel kinda uneasy waiting that long for it. Thanx. |
