Classical reverse Audi A3 noises and some tips to maintain your gearbox

Why does the reversing of my Audi A3 make a different noise from my other speeds?

De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The sound generated by the reversing of your Audi A3 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 car in the revs, you risk to burn your clutch or gnawing at the gearbox pinions.

  • Never reverse while the car 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 exert on the gears will be significant and you will create a premature wear and tear of the gears. You can even destroy the gears of your gearbox at speed by doing so. It will therefore be completely typical if you notice a reverse noise on your Audi A3 if you shift gear under these conditions.

If you experience a grinding noise when you start in reverse with your Audi A3, it may be the engine mounts that are tired. Certainly, when the engine is in reverse gear, due to the pinions we saw above the vibrations generated by the gearbox are higher and it is therefore conceivable that due to their wear the silentblocks no longer absorb the engine vibrations well.

If you are subject to a knocking noise when you are in reverse with your Audi A3 and this noise tends to increase as you gain speed.

It is therefore time to empty the box.
