It is never pleasing to hear a sound on your vehicle that you don’t know where it comes from. You may be questioning what to do when you identify a reversing gear noise that continues on your Volkswagen Polo? Any gearbox trouble can be critical, but before making sure, it is better to do a few investigations. Our team has made this article to help you resolve it. First, we will see what the sources and the different gearbox noises can be on Volkswagen Polo, and second, what are the solutions available to you.
Classical reverse Volkswagen Polo noises and some tips to maintain your gearbox
Why does the reversing of my Volkswagen Polo make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult action. The noise made by the reversing of your Volkswagen Polo 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 much less important than with spur gears implemented 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 plan. In fact, the pressure you will apply on the gears will be significant and you will make 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 normal if you perceive a reverse noise on your Volkswagen Polo if you shift gear under these conditions.
Several Volkswagen Polo reversing noises and their origins
Finally in this section, we will move on to what you are probably most curious about in this content, to learn about the origin of reversing noise on Volkswagen Polo. Here are the 3 typical sounds you may be victim of.
I notice a grinding noise when starting in reverse gear
If you hear a grinding noise when you start in reverse with your Volkswagen Polo, it may be the engine mounts that are tired. Indeed, when the engine is in reverse gear, due to the pinions we saw above the vibrations made by the gearbox are higher and it is therefore plausible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this situation, do not hesitate to check this content for more information about strut mount noises on Volkswagen Polo.
An increased reverse knocking noise on Volkswagen PoloX
If you are subject to a knocking noise when you are in reverse with your Volkswagen Polo and this noise tends to amplify as you gain speed. It is plausible that you are experiencing a serious trouble that needs to be resolved as soon as possible before wrecking your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will propagate to the rest of the box and damage other gears very fast. Take your vehicle to your auto technician quickly or check out this article about gearbox noise on Volkswagen Polo for more details.
I listen to a noise when I go in reverse
Finding out a noise when you shift into reverse is normal and related to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Volkswagen Polo reverse gear makes more noise than before, it is plausible that filings have been produced and are moving around in it. It is therefore time to empty the box.
