2008 528i Vibration at idle
I'm new to this forum. I just purchased a certified 2008 528i. When the car is at idle there is a sound vibration in the car. If I press on the accelerator and raise the idle just a bit, the sound vibration goes away and it runs smooth. The sound it makes when it vibrates is similar to the sound when you set the radio with too much bass. It is an annoying boomy sound.
I took it to the dealer, and they said that the put it on the computer and that everything was fine, but it the sound is very irritating to me. I asked them if they could raise the idle and they said that it is all set with the computer and is fine. Has anyone had experience with this? Is it true that the idle cannot be raised?
Thanks in advance.
