Where your motoring questions are answered When I drive my BMW 528i over 45km/h, there is a 'whooshing' sound on the off-side front door. My mechanic says there is nothing wrong with the car. Paul Uy, Mid-Levels BMW Concessionaires Hong Kong service manager Steven Adolpho says: Look to see whether the noise is from the wind or from the chassis body or drive train. Under this type of situation it is always advisable to road test the vehicle with the customer in order to confirm the problem. As most people interpret noises differently. In the case of wind noise, confirm whether or not the noise is in the actual door area or associated components. For example, an incorrectly adjusted bonnet lid or headlamp unit may result in a wind noise that appears to be coming from the door. If the wind noise is coming from the door area then several basic checks can be made prior to the testing of the vehicle: check the door and window-surround seals for damage; the door and window for correct adjustment; the door mirror for damage and correct adjustment; and associated body damage. If the above checks do not indicate a problem, we would use masking tape to cover the entire door and window edges prior to conducting a road test, then test the car to confirm whether the noise has been eliminated. Sections of the tape would then be systematically removed until the noise reappeared. Once the noise is localised, corrective measures can be taken. The majority of wind and body noises can be simply rectified. Are you rattled by something in your car?
