Classical reverse Audi S4 noises and some tips to maintain your gearbox
Why does the reversing of my Audi S4 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult process. The noise caused by the reversing of your Audi S4 is logical. It can be explained in a fairly simple way. In fact, the gears used for conventional speeds (1st to 5th or 6th) are so-called “helical” gears (oblique gears) . The use of such a pinion makes the noise caused by the gears less important than with spur gears used for the reverse gear.
Tips to reduce wear on your clutch and gearbox

Reversing the direction of operation of the gearbox during operation is a very bad plan.
