Classical reverse Audi A7 noises and some tips to look after your gearbox
Why does the reversing of my Audi A7 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The noise generated by the reversing of your Audi A7 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 more quiet than with spur gears employed for the reverse gear.
Tips to limit wear on your clutch and gearbox
