Noises in the gearbox (Audi A4 B5)

Over time, noises developing in the gearbox may attract attention. In this case, you should first check the oil level in the gearbox.

• If a whining sound appears in any gear and its tone changes when the gas is increased or decreased, then the teeth of the gear pair in that gear may be worn out.
• If the rustling occurs in all gears, then the cause lies in the main gear or gearbox shaft bearings.
• Rough grinding noises that are only heard when the gearbox is hot indicate beating synchronizing rings. When the oil liquefies, it is squeezed out by the synchronizing ring always in the same place.
• The noises that occur when the torsion differential is operating, which occur when starting to move in quattro with the steering wheel turned sharply, are normal and are due to the design.
