501-25-89 Body Repairs - General Information 501-25-89 DESCRIPTION AND OPERATION 2 1 Z0121164 There are ducts present on the doors for the electrical or mechanical adjusters for the exterior mirrors. If there are leaks, wind noises will be caused. Holes can also be present at the transition to other components. Remedial Action If there is inadequate sealing of the foam seals -2- they must be replaced or supplemented with suitable material. Transitions to other components can be sealed with butyl sealing compound -1-. Moldings, covers, door handles, windshield wiper arms Moldings and covers especially tend to cause wind noises because of their location. These components interrupt smooth bodywork surfaces and air turbulence therefore arises at the edges. If there are noise concerns in the area of the doors, check especially for gaps and projections. Moldings must not stand away from the bodywork or the door. There must not be any gaps or discontinuities at the location of joints. Incorrectly adjusted windshield wiper arms can cause wind noises. Especially if they are too far over the glass surface when in the rest position. Wind noises in the transition area between the air cowl cover and the wing or the windshield can be caused by an incorrectly installed air cowl cover. At high air speeds the air cowl cover may lift and noises will then occur. Because of their necessary mechanical features, door handles have a range of openings and edges which allow noise to be generated. The door handle can be masked off for testing purposes. If a reduction in wind noises is noticed, inadequate sealing may be the reason for the noises. Remedial Action Openings which are used to secure trim panels must be checked for leaks. Any leaks found can be rectified using butyl strips. TIZ0121052 Loose or damaged outer trim on the pillars -arrow- must be secured or replaced. mm 1 2 E46718 A butyl sealing strip -1- can be laid underneath the cover in the transition area between the air cowl cover and the wing or windshield. The sealing of the door handles must be renewed when required. In addition, noise absorbing material can be applied to the back of the door handles.
