Classical reverse Audi A4 noises and some tips to preserve your gearbox

Why does the reversing of my Audi A4 make a different noise from my other speeds?

De facto, adding all gears, bearings and pinions into a gearbox is a difficult action. The sound induced by the reversing of your Audi A4 is logical. It can be explained in a fairly simple way. Indeed, 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 chosen for the reverse gear.

Tips to limit wear on your clutch and gearbox

  • Don’t give a big boost:
    Indeed, if you kick the throttle hard when you are in reverse or when you put the vehicle in the revs, you risk to burn your clutch or gnawing at the gearbox pinions.

  • Never reverse while the vehicle is in motion or vice versa:
    Reversing the direction of operation of the gearbox during operation is a very bad idea. Indeed, the pressure you will apply on the gears will be enormous and you will create a premature wear and tear of the gears. You can even break the gears of your gearbox at speed by doing so. It will therefore be completely typical if you find out a reverse noise on your Audi A4 if you shift gear under these conditions.
