It is never pleasant 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 find a reversing gear noise that persists on your Bmw Serie 1 E82? Any gearbox issue can be critical, but before making sure, it is better to do a few investigations. Our team has created this article to help you fix it. First, we will see what the origins and the different gearbox noises can be on Bmw Serie 1 E82, and second, what are the solutions available to you.
Classical reverse Bmw Serie 1 E82 noises and some tips to maintain your gearbox
Why does the reversing of my Bmw Serie 1 E82 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult exercise. The noise induced by the reversing of your Bmw Serie 1 E82 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
- 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 choice. In fact, the pressure you will put in on the gears will be monumental 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 typical if you experience a reverse noise on your Bmw Serie 1 E82 if you shift gear under these conditions.
Different Bmw Serie 1 E82 reversing noises and their origins
Finally in this section, we will move on to what you are probably most excited about in this article, to learn about the source of reversing noise on Bmw Serie 1 E82. Here are the 3 typical sounds you may be victim of.
I acknowledge a grinding noise when starting in reverse gear
If you hear a grinding noise when you start in reverse with your Bmw Serie 1 E82, 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 produced 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 circumstance, do not hesitate to check out this paper for more details about strut mount noises on Bmw Serie 1 E82.
An increased reverse knocking noise on Bmw Serie 1 E82X
If you are subject to a knocking noise when you are in reverse with your Bmw Serie 1 E82 and this noise tends to amplify as you gain speed. It is plausible that you are dealing with a serious issue 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 before long. Take your vehicle to your auto mechanic quickly or read this content page about gearbox noise on Bmw Serie 1 E82 for more details.
I perceive a noise when I go in reverse
Listening 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 Bmw Serie 1 E82 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.
