Our '04 330 xi sliptronic, when in D with brake applied, e.g. stopped at a light, seems to have a buzz or vibration throughout the car. Does not seem right to me. Do any of you others have this, evident through the steering wheel, and also slightly audible? I am worried that perhaps something is slightly touching the fram or exhaust system, since of course we do get a new tranny every few weeks. Thanks.
