Assessm ent | Type of wind noises | Place of origin |
Normal | "Normal" wind noises | Roof, side windows |
Normal | Noises caused partly by changes in the direction of air flow and by air flow around separate components | A-pillars, outside mirrors, antennas |
Serious | Noises caused by vibrating seals | Door gaps too large, door/ window seals not making firm contact |
Serious | Air escape and air passage noises | Leaks in the bodywork/ sealing system |
Serious | Cavity noises | Unsealed bodywork cavities |
Those noises listed under "Serious" indicate a possible source of the fault.

Furthermore, the following points should be noted:
